Accounting Policies [Abstract] | |
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: BUSINESS: Aehr Test Systems (the “Company”) was incorporated in California in May 1977 and primarily designs, engineers and manufactures test and burn-in equipment used in the semiconductor industry. The Company’s principal products are the Advanced Burn-In and Test System, or ABTS, the FOX full wafer contact parallel test and burn-in systems, the MAX burn-in system, WaferPak full wafer contactor, the DiePak carrier and test fixtures. LIQUIDITY: Since inception, the Company has incurred substantial cumulative losses and negative cash flows from operations. In response, the Company took steps to minimize expense levels, entered into credit arrangements, and raised capital through public and private equity offerings, to increase the likelihood that it will have sufficient cash to support operations. At May 31, 2019, the Company had $5.4 million in cash and cash equivalents. The Company anticipates that the existing cash balance together with income from operations, collections of existing accounts receivable, revenue from our existing backlog of products, the sale of inventory on hand, and deposits and down payments against significant orders will be adequate to meet its working capital and capital equipment requirements. We believe our existing cash and cash equivalents will be sufficient to meet our anticipated cash needs over the next 12 months. Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, the timing and cost of establishing additional sales and marketing capabilities, the timing and cost to introduce new and enhanced products and the timing and cost to implement new manufacturing technologies. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. Any additional debt financing obtained by us in the future could also involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. Additionally, if we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to grow or support our business and to respond to business challenges could be significantly limited. CONSOLIDATION: The consolidated financial statements include the accounts of the Company and both its wholly-owned and majority-owned foreign subsidiaries. Intercompany accounts and transactions have been eliminated. FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS: Assets and liabilities of the Company’s foreign subsidiaries and a branch office are translated into U.S. Dollars from their functional currencies of Japanese Yen, Euros and New Taiwan Dollars using the exchange rate in effect at the balance sheet date. Additionally, their net sales and expenses are translated using exchange rates approximating average rates prevailing during the fiscal year. Translation adjustments that arise from translating their financial statements from their local currencies to U.S. Dollars are accumulated and reflected as a separate component of shareholders’ equity (deficit). Transaction gains and losses that arise from exchange rate changes denominated in currencies other than the local currency are included in the Consolidated Statements of Operations as incurred. See Note 12 for the detail of foreign exchange transaction gains and losses for all periods presented. USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates in the Company’s consolidated financial statements include allowance for doubtful accounts, valuation of inventory at the lower of cost or market, and warranty reserves. CASH EQUIVALENTS: Cash equivalents consist of money market instruments purchased with an original maturity of three months or less. These investments are reported at fair value. ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS: Accounts receivable are derived from the sale of products throughout the world to semiconductor manufacturers, semiconductor contract assemblers, electronics manufacturers and burn-in and test service companies. Accounts receivable are recorded at the invoiced amount and are not interest bearing. The Company maintains an allowance for doubtful accounts to reserve for potentially uncollectible trade receivables. The Company also reviews its trade receivables by aging category to identify specific customers with known disputes or collection issues. The Company exercises judgment when determining the adequacy of these reserves as the Company evaluates historical bad debt trends, general economic conditions in the United States and internationally, and changes in customer financial conditions. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received. No significant adjustments to the allowance for doubtful accounts were recorded during the fiscal years ended May 31, 2019, 2018 or 2017. CONCENTRATION OF CREDIT RISK: The Company sells its products primarily to semiconductor manufacturers in North America, Asia, and Europe. As of May 31, 2019, approximately 49%, 25% and 26% of gross accounts receivable were from customers located in North America, Asia and Europe, respectively. As of May 31, 2018, approximately 55%, 45% and 0% of gross accounts receivable were from customers located in North America, Asia, and Europe, respectively. Three customers accounted for 44%, 25% and 21% of gross accounts receivable as of May 31, 2019. Three customers accounted for 38%, 32% and 11% of gross accounts receivable as of May 31, 2018. Four customers accounted for 36%, 14%, 12% and 10% of net sales in fiscal 2019. Three customers accounted for 34%, 26% and 13% of net sales in fiscal 2018. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company uses letter of credit terms for some of its international customers. The Company’s cash and cash equivalents are generally deposited with major financial institutions in the United States, Japan, Germany and Taiwan. The Company invests its excess cash in money market funds and U.S. Treasury securities. The money market funds bear the risk associated with each fund. The money market funds have variable interest rates. The Company has not experienced any material losses on its money market funds or short-term cash deposits. CONCENTRATION OF SUPPLY RISK: The Company relies on subcontractors to manufacture many of the components and subassemblies used in its products. Quality or performance failures of the Company’s products or changes in its manufacturers’ financial or business condition could disrupt the Company’s ability to supply quality products to its customers and thereby have a material and adverse effect on its business and operating results. Some of the components and technologies used in the Company’s products are purchased and licensed from a single source or a limited number of sources. The loss of any of these suppliers may cause the Company to incur additional transition costs, result in delays in the manufacturing and delivery of its products, or cause it to carry excess or obsolete inventory and could cause it to redesign its products. INVENTORIES: Inventories include material, labor and overhead, and are stated at the lower of cost (first-in, first-out method) or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less costs of completion, disposal and transportation. Provisions for excess, obsolete and unusable inventories are made after management’s evaluation of future demand and market conditions. The Company adjusts inventory balances to approximate the lower of its manufacturing costs or net realizable value. If actual future demand or market conditions become less favorable than those projected by management, additional inventory write-downs may be required, and would be reflected in cost of sales in the period the revision is made. PROPERTY AND EQUIPMENT: Property and equipment are stated at cost less accumulated depreciation and amortization. Major improvements are capitalized, while repairs and maintenance are expensed as incurred. Leasehold improvements are amortized over the lesser of their estimated useful lives or the term of the related lease. Furniture and fixtures, machinery and equipment, and test equipment are depreciated on a straight-line basis over their estimated useful lives. The ranges of estimated useful lives are generally as follows: Furniture and fixtures 2 to 6 years Machinery and equipment 3 to 6 years Test equipment 4 to 6 years REVENUE RECOGNITION: In May 2014, the FASB issued FASB ASC Topic 606, Revenue from Contracts with Customers Revenue Recognition The adoption of ASC 606 did not have a material impact on our consolidated financial statements as of June 1, 2018. No adjustment was recorded to accumulated deficit as of the adoption date and reported revenue would not have been different under legacy GAAP. Additionally, we do not expect the adoption of the revenue standard to have a material impact to our net income on an ongoing basis. We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors. We consider revenue to be earned when all of the following criteria are met: ● We have a contract with a customer that creates enforceable rights and obligations, ● Promised performance obligations are identified, ● The transaction price, or the amount we expect to receive, is determinable and ● We have satisfied the performance obligations to the customer. Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services. PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE: Costs incurred in the research and development of new products or systems are charged to operations as incurred. Costs incurred in the development of software programs for the Company’s products are charged to operations as incurred until technological feasibility of the software has been established. Generally, technological feasibility is established when the software module performs its primary functions described in its original specifications, contains features required for it to be usable in a production environment, is completely documented and the related hardware portion of the product is complete. After technological feasibility is established, any additional costs are capitalized. Capitalization of software costs ceases when the software is substantially complete and is ready for its intended use. Capitalized costs are amortized over the estimated life of the related software product using the greater of the units of sales or straight-line methods over ten years. No system software development costs were capitalized or amortized in fiscal 2019, 2018 and 2017. IMPAIRMENT OF LONG-LIVED ASSETS: In the event that facts and circumstances indicate that the carrying value of assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset would be compared to the asset’s carrying value to determine if a write-down is required. ADVERTISING COSTS: The Company expenses all advertising costs as incurred and the amounts were not material for all periods presented. SHIPPING AND HANDLING OF PRODUCTS: Amounts billed to customers for shipping and handling of products are included in net sales. Costs incurred related to shipping and handling of products are included in cost of sales. INCOME TAXES: Income taxes have been provided using the liability method whereby deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and net operating loss and tax credit carryforwards measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse or the carryforwards are utilized. Valuation allowances are established when it is determined that it is more likely than not that such assets will not be realized. A full valuation allowance was established against all deferred tax assets, as management determined that it is more likely than not that deferred tax assets will not be realized, as of May 31, 2019 and 2018. The Company accounts for uncertain tax positions consistent with authoritative guidance. The guidance prescribes a “more likely than not” recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not expect any material change in its unrecognized tax benefits over the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes. Although the Company files U.S. federal, various state, and foreign tax returns, the Company’s only major tax jurisdictions are the United States, California, Germany and Japan. Tax years 1996 – 2018 remain subject to examination by the appropriate governmental agencies due to tax loss carryovers, research and development tax credits, or other tax attributes from those years. COMPREHENSIVE (LOSS) INCOME: Comprehensive (loss) income generally represents all changes in shareholders’ equity except those resulting from investments or contributions by shareholders. Unrealized gains and losses on foreign currency translation adjustments are included in the Company’s components of comprehensive (loss) income, which are excluded from net (loss) income. Comprehensive (loss) income is included in the statements of comprehensive (loss) income. RECENT ACCOUNTING PRONOUNCEMENTS: Accounting Standards Adopted Revenue Recognition In May 2014, the FASB issued Accounting Standards Codification (“ASC”) Update No. 2014-09, Revenue from Contracts with Customers The Company adopted ASC 606 on June 1, 2018, the first day of fiscal 2019, using the modified retrospective method. The Company applied ASC 606 to all contracts not completed as of the date of adoption in order to determine any adjustment to the opening balance of retained earnings. Under the modified retrospective adoption method, the comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods, ASC 605, " Revenue Recognition The adoption of ASC 606 did not have a material impact on the Company’s consolidated financial statements as of June 1, 2018. No adjustment was recorded to accumulated deficit as of the adoption date and reported revenue would not have been different under legacy GAAP. Additionally, the Company does not expect the adoption of the revenue standard to have a material impact to the Company’s net income on an ongoing basis. Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued authoritative guidance related to the classification of certain cash receipts and cash payments on the statement of cash flows. The Company adopted this new standard in fiscal year 2019. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Intra-Entity Asset Transfers In October 2016, the FASB issued an accounting standard update that requires recognition of the income tax consequences of intra-entity transfers of assets (other than inventory) at the transaction date. The Company adopted this new standard in fiscal year 2019. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Restricted Cash. In November 2016, the FASB issued authoritative guidance related to statements of cash flows. This guidance clarifies that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts shown on the statement of cash flows. The Company adopted this new standard in fiscal year 2019. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Income Taxes On December 22, 2017, the US government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the US tax code including but not limited to (1) reducing the US federal corporate tax rate from 34% to 21%; (2) requiring companies to pay a one-time transition tax on certain repatriated earnings of foreign subsidiaries; (3) generally eliminating US federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in US federal income of certain earnings of controlled foreign corporations; (5) creating a new limitation on deductible interest expense; (6) changing rules related to the uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017, and (7) repealing the corporate alternative minimum tax regime, or AMT, effective December 31, 2017 and permitting existing minimum tax credits to offset the regular tax liability for any tax year. Consequently, the Company has accounted for the reduction of $6.4 million of deferred tax assets with an offsetting adjustment to the valuation allowance for the fiscal year ended 2018, and recorded a benefit of $90,000 for the Company’s Federal refundable AMT credit. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. There are also certain transitional impacts of the Tax Act. As part of the transition to the new territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries. The Company is not subject to the transition tax. The one-time transition tax is based on post-1986 earnings and profits that were previously deferred from U.S. income tax. The Company has finalized its calculation of the total post-1986 earnings and profits for its foreign corporations. Based on the Company’s net operating loss carryovers and valuation allowance, there is no impact to its consolidated financial statements as a result of the completion of the analysis. Accounting Standards Not Yet Adopted Financial Instruments In January 2016, the FASB issued an accounting standard update related to recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, it clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This standard is effective for us in fiscal year 2020. Early adoption is permitted. The Company does not expect a material impact of this new guidance on its consolidated financial statements. In June 2016, the FASB issued an accounting standard update that requires measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2021 on a modified retrospective basis, and early adoption in fiscal 2020 is permitted. The Company does not expect a material impact of this accounting standard update on its consolidated financial statements. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases |

Revenue from Contract with Customer [Abstract] | |
2. REVENUE | 2. REVENUE: Revenue recognition The Company recognizes revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process, (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below. Performance obligations include sales of systems, contactors, spare parts, and services, as well as, installation and training services included in customer contracts. A contract’s transaction price is allocated to each distinct performance obligation. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. The Company generally does not grant return privileges, except for defective products during the warranty period. For contracts that contain multiple performance obligations, the Company allocates the transaction price to the performance obligations on a relative standalone selling price basis. Standalone selling prices are based on multiple factors including, but not limited to historical discounting trends for products and services and pricing practices in different geographies. Revenue for systems and spares are recognized at a point in time, which is generally upon shipment or delivery. Revenue from services is recognized over time as services are completed or ratably over the contractual period of generally one year or less. The Company has elected the practical expedient under ASC 606 to not assess whether a contract has a significant financing component as the Company’s standard payment terms are less than one year. Disaggregation of revenue The following tables show revenues by major product categories. Within each product category, contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flow are substantially similar. The Company’s revenues by product category are as follows (in thousands): Year Ended May 31, 2019 2018 2017 Type of good / service: Systems $ 9,566 $ 18,174 $ 12,115 Contactors 6,154 6,500 1,991 Services 5,336 4,881 4,792 $ 21,056 $ 29,555 $ 18,898 Product lines: Wafer-level $ 14,618 $ 13,080 $ 9,582 Test During Burn-In 6,438 16,475 9,316 $ 21,056 $ 29,555 $ 18,898 The following presents information about the Company’s operations in different geographic areas. Net sales are based upon ship-to location (in thousands): Year Ended May 31, 2019 2018 2017 Geographic region: United States $ 13,468 $ 8,446 $ 7,762 Asia 5,648 19,973 10,439 Europe 1,940 1,136 697 $ 21,056 $ 29,555 $ 18,898 With the exception of the amount of service contracts and extended warranties, the Company’s product category revenues are recognized at point in time when control transfers to customers. Year Ended May 31, 2019 2018 2017 Timing of revenue recognition (in thousands): Products and services transferred at a point in time $ 18,473 $ 27,337 $ 17,193 Services transferred over time 2,583 2,218 1,705 $ 21,056 $ 29,555 $ 18,898 Contract balances A receivable is recognized in the period the Company delivers goods or provides services or when the Company’s right to consideration is unconditional. The Company usually does not record contract assets because the Company has an unconditional right to payment upon satisfaction of the performance obligation, and therefore, a receivable is more commonly recorded than a contract asset. Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the Condensed Consolidated Balance Sheets at the end of each reporting period as a component of deferred revenue. Contract liabilities as of May 31, 2019 and 2018 were $1,734,000 and $2,089,000, respectively. During the fiscal year ended May 31, 2019, the Company recognized $1,273,000 of revenues that were included in contract liabilities as of May 31, 2018. Remaining performance obligations On May 31, 2019, the Company had $731,000 of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 74% of its remaining performance obligations as revenue in fiscal 2020, and an additional 26% in fiscal 2021 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation. Costs to obtain or fulfill a contract The Company generally expenses sales commissions when incurred as a component of selling, general and administrative expense as the amortization period is typically less than one year. Additionally, the majority of the Company’s cost of fulfillment as a manufacturer of products is classified as inventory and fixed assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of the Company’s products and their respective manufacturing process. |

Earnings Per Share [Abstract] | |
3. EARNINGS PER SHARE (EPS) | 3. EARNINGS PER SHARE (“EPS”): Basic EPS is determined using the weighted average number of common shares outstanding during the period. Diluted EPS is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, RSUs and ESPP shares) outstanding during the period using the treasury stock method. The following table presents the computation of basic and diluted net (loss) income per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data): Year Ended May 31, 2019 2018 2017 Numerator: Net (loss) income $ (5,235 ) $ 528 $ (5,653 ) Denominator for basic net (loss) income per share: Weighted-average shares outstanding 22,387 21,732 16,267 Shares used in basic net (loss) income per share calculation 22,387 21,732 16,267 Effect of dilutive securities — 1,050 — Denominator for diluted net (loss) income per share 22,387 22,782 16,267 Basic net (loss) income per share $ (0.23 ) $ 0.02 $ (0.35 ) Diluted net (loss) income per share $ (0.23 ) $ 0.02 $ (0.35 ) For the purpose of computing diluted earnings per share, the weighted average number of potential common shares does not include stock options with an exercise price greater than the average fair value of the Company’s common stock for the period, as the effect would be anti-dilutive. In the fiscal years ended May 31, 2019 and 2017, potential common shares have not been included in the calculation of diluted net loss per share as the effect would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for these periods are the same. Stock options to purchase 3,107,000 and 3,074,000 shares of common stock were outstanding on May 31, 2019 and 2017, respectively, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. Stock options to purchase 1,313,000 shares of common stock were outstanding as of May 31, 2018 but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. ESPP rights to purchase 297,000 and 169,000 ESPP shares were outstanding on May 31, 2019 and 2017, respectively, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. RSUs for 23,000 shares and 32,000 shares were outstanding on May 31, 2019 and 2017, respectively, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. The 2,657,000 shares convertible under the Convertible Notes outstanding on May 31, 2018 and 2017 were not included in the computation of diluted net income (loss) per share, because the inclusion of such shares would be anti-dilutive. |

Fair Value Disclosures [Abstract] | |
4. FAIR VALUE OF FINANCIAL INSTRUMENTS | 4. FAIR VALUE OF FINANCIAL INSTRUMENTS: The Company’s financial instruments are measured at fair value consistent with authoritative guidance. This authoritative guidance defines fair value, establishes a framework for using fair value to measure assets and liabilities, and disclosures required related to fair value measurements. The guidance establishes a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels: Level 1 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments. Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value. The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of May 31, 2019 (in thousands): Balance as of May 31, 2019 Level 1 Level 2 Level 3 Money market funds $ 3,017 $ 3,017 $ — $ — Assets $ 3,017 $ 3,017 $ — $ — The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of May 31, 2018 (in thousands): Balance as of May 31, 2018 Level 1 Level 2 Level 3 Money market funds $ 7,813 $ 7,813 $ — $ — U.S. Treasury securities 5,983 5,983 — — Assets $ 13,796 $ 13,796 $ — $ — The U.S. Treasury securities as of May 31, 2018 have maturities of three months and have no unrealized gain or loss. Included in Money market funds as of May 31, 2019 and 2018 is $80,000 restricted cash representing a security deposit for the Company’s United States manufacturing and office space lease. There were no financial liabilities measured at fair value as of May 31, 2019 and 2018. There were no transfers between Level 1 and Level 2 fair value measurements during the fiscal years ended May 31, 2019 and 2018. The carrying amounts of financial instruments including cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities, approximate fair value due to their short maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, the carrying value of the debt approximates the fair value. |

As of May 31, 2019 and 2018, the Company concluded that it is more likely than not that the deferred tax assets will not be realized and therefore provided a full valuation allowance against the deferred tax assets. The Company will continue to evaluate the need for a valuation allowance against its deferred tax assets on a quarterly basis. At May 31, 2019, the Company had federal and state net operating loss carryforwards of $53,803,000 and $29,504,000 respectively. The federal and state net operating loss carryforwards will begin to expire in 2024. At May 31, 2019, the Company also had federal and state research and development tax credit carryforwards of $2,071,000 and $5,609,000, respectively. The federal credit carryforward will begin to expire in 2022, and the California credit will carryforward indefinitely. These carryforwards may be subject to certain limitations on annual utilization in case of a change in ownership, as defined by tax law. The Company also has alternative minimum tax credit carryforwards of $34,000 for state purposes. The credits may be used to offset regular tax and do not expire. The Company has made no provision for U.S. income taxes on undistributed earnings of certain foreign subsidiaries because it is the Company’s intention to permanently reinvest such earnings in its foreign subsidiaries. If such earnings were distributed, the Company would be subject to additional U.S. income tax expense. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable. Foreign net operating loss carryforwards of $345,000 are available to reduce future foreign taxable income. The foreign net operating losses will expire starting in fiscal year 2021. The Company maintains liabilities for uncertain tax positions. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available. The aggregate changes in the balance of gross unrecognized tax benefits are as follows (in thousands): Beginning balance as of May 31, 2016 $ 789 Decreases related to prior year tax positions — Decreases related to lapse of statute of limitations — Balance at May 31, 2017 $ 789 Increases related to prior year tax positions 889 Increases related to current year tax positions 107 Balance at May 31, 2018 $ 1,785 Decreases related to prior year tax positions (41 ) Increases related to current year tax positions 65 Balance at May 31, 2019 $ 1,809 The ending balance of $1,809,000 of unrecognized tax benefits as of May 31, 2019, if recognized, would not impact the effective tax rate. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. As part of the transition to the new territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries. The company is not subject to the transition tax. The one-time transition tax is based on post-1986 earnings and profits that were previously deferred from U.S. income tax. During fiscal 2019 the Company finalized its calculation of the transition tax and due to carryover losses and the valuation allowance the Company determined there was no impact to the financial statements as a result of the completion of the analysis. The Tax Act also repealed the corporate alternative minimum tax, or AMT, effective December 31, 2017. The Tax Act repealed the corporate alternative minimum tax regime and permits existing minimum tax credits to offset the regular tax liability for any tax year. Further, the credit is refundable for any tax year beginning after December 31, 2017 and before December 31, 2020 in an amount equal to 50% of the excess of the minimum tax credit over the allowable credit for the year against the regular tax liability. Any unused minimum tax credit carryforward is refundable in the following year. As result, the Company recorded a benefit of $90,000 for its federal refundable AMT credit in its fiscal 2018 tax provision. In addition, the reduction of U.S. federal corporate tax rate reduces the corporate tax rate to 21%, effective January 1, 2018. Consequently, the Company has accounted for the reduction of $6.4 million of deferred tax assets with an offsetting adjustment to the valuation allowance. Although the Company files U.S. federal, various state, and foreign tax returns, the Company’s only major tax jurisdictions are the United States, California, Germany and Japan. Tax years 1996 – 2018 remain subject to examination by the appropriate governmental agencies due to tax loss carryovers, research and development tax credits, or other tax attributes from those years. |

Long-term Debt, Unclassified [Abstract] | |
8. LONG-TERM DEBT | 8. LONG-TERM DEBT: On April 10, 2015, the Company entered into a Convertible Note Purchase and Credit Facility Agreement (the “Purchase Agreement”) with QVT Fund LP and Quintessence Fund L.P. (the “Purchasers”) providing for (a) the Company’s sale to the Purchasers of $4,110,000 in aggregate principal amount of 9.0% Convertible Secured Notes due 2017 (the “Convertible Notes”) and (b) a secured revolving loan facility (the “Credit Facility”) in an aggregate principal amount of up to $2,000,000. On August 22, 2016 the Purchase Agreement was amended to extend the maturity date of the Convertible Notes to April 10, 2019, decrease the conversion price from $2.65 per share to $2.30 per share, decrease the forced conversion price from $7.50 per share to $6.51 per share, and allow for additional equity awards. The maximum amount of $2,000,000 drawn against the Credit Facility was converted to Convertible Notes, and at May 31, 2018 there was no remaining balance available to be drawn on the Credit Facility. The Convertible Notes bore interest at an annual rate of 9.0%. Interest was payable quarterly on March 1, June 1, September 1 and December 1 of each year. Debt issuance costs of $356,000, which were accreted over the term of the original loan using the effective interest rate method, were offset against the loan balance. The conversion price for the Convertible Notes was $2.30 per share and was subject to adjustment upon the occurrence of certain specified events. Holders could convert all or any part of the principal amount of their Convertible Notes in integrals of $10,000 at any time prior to the maturity date. Upon conversion, the Company would deliver shares of its common stock to the holder of Convertible Notes electing such conversion. The Company could not redeem the Convertible Notes prior to maturity. The Company’s obligations under the Purchase Agreement were secured by substantially all of the assets of the Company. On the maturity date of April 10, 2019, the Company paid off the Convertible Notes in an aggregate principal amount of $6.1 million. |

Stock-based compensation expense for stock options and ESPP purchase rights is measured at each grant date, based on the fair value of the award using the Black-Scholes option valuation model, and is recognized as expense over the employee’s requisite service period. This model was developed for use in estimating the value of publicly traded options that have no vesting restrictions and are fully transferable. The Company’s employee stock options have characteristics significantly different from those of publicly traded options. For RSUs, stock-based compensation expense is based on the fair value of the Company’s common stock at the grant date. All of the Company’s stock-based compensation is accounted for as equity instruments. The following table summarizes the stock-based compensation expense for the fiscal years ended May 31, 2019, 2018 and 2017 (in thousands, except per share data): Year Ended May 31, 2019 2018 2017 Stock-based compensation in the form of stock options, RSUs, and ESPP purchase rights, Cost of sales $ 104 $ 148 $ 91 Selling, general and administrative 545 592 714 Research and development 256 256 194 Net effect on net income (loss) $ 905 $ 996 $ 999 Effect on net income (loss) per share: Basic $ 0.04 $ 0.05 $ 0.06 Diluted $ 0.04 $ 0.04 $ 0.06 As of May 31, 2019, 2018 and 2017, there were no stock-based compensation expenses capitalized as part of inventory. During fiscal 2019, 2018 and fiscal 2017, the Company recorded stock-based compensation related to stock options and restricted stock units of $650,000, $706,000 and $884,000, respectively. As of May 31, 2019, the total compensation expense related to unvested stock-based awards under the Company’s 2016 Equity Incentive Plan, but not yet recognized, was $1,182,000 which is net of estimated forfeitures of $3,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 3.0 years. During fiscal 2019, 2018 and fiscal 2017, the Company recorded stock-based compensation related to its ESPP of $255,000, $290,000 and $115,000, respectively. The increase in fiscal 2018 is primarily due to employees increasing their ESPP elections during the fiscal year. As of May 31, 2019, the total compensation expense related to purchase rights under the ESPP but not yet recognized was $179,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 1.2 years. Valuation Assumptions Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation method and a single option award approach. The fair value under the single option approach is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Expected Term. The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined based on historical experience, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as evidenced by changes to the terms of its stock-based awards. Volatility. Volatility is a measure of the amounts by which a financial variable such as stock price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company uses the historical volatility for the past five years, which matches the expected term of most of the option grants, to estimate expected volatility. Volatility for each of the ESPP’s four time periods of six months, twelve months, eighteen months, and twenty-four months is calculated separately and included in the overall stock-based compensation expense recorded. Risk-Free Interest Rate. The Company bases the risk-free interest rate used in the Black-Scholes option valuation method on the implied yield in effect at the time of option grant on U.S. Treasury zero-coupon issues with a remaining term equivalent to the expected term of the stock awards including the ESPP. Fair Value. The fair values of the Company’s stock options granted to employees in fiscal 2019, 2018 and 2017 were estimated using the following weighted average assumptions in the Black-Scholes option valuation method: Year Ended May 31, 2019 2018 2017 Expected term (in years) 5 4 4 Volatility 0.72 0.77 0.81 Risk-free interest rates 2.83 % 1.95 % 1.02 % Weighted-average grant date fair value $ 1.33 $ 2.07 $ 1.09 The fair value of our ESPP purchase rights for the fiscal 2019, 2018 and 2017 was estimated using the following weighted-average assumptions: Year End May 31, 2019 2018 2017 Expected term (in years) 0.5 – 2.0 0.5 – 2.0 0.5 – 2.0 Volatility 0.48 – 0.78 0.56 – 0.81 0.79 – 1.08 Risk-free interest rates 2.33%-2.82 % 1.92%-2.25 % 0.48%-0.80 % Weighted-average grant date fair value $ 1.14 $ 1.01 $ 1.65 EQUITY INCENTIVE PLAN: In October 2006, the Company’s 2006 Equity Incentive Plan was approved by the shareholders, which provides for granting of incentive stock options, non-statutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, performance shares and other stock or cash awards as the Company’s Board of Directors may determine. In October 2016, the Company’s 2016 Equity Incentive Plan was approved by the Company’s shareholders. The 2016 Equity Incentive Plan replaced our 2006 Equity Incentive Plan, which was scheduled to expire in October 2016, and will continue in effect until 2026. A total of 2,238,000 shares of common stock have been reserved for issuance under the Company’s 2016 Equity Incentive Plan, which includes 1,438,000 shares that remained available for issuance under the 2006 Equity Incentive Plan. See the Company’s Registration Statement on Form S-8 filed with the Securities and Exchange Commission on November 14, 2016 for further information regarding the 2016 Equity Incentive Plan. As of May 31, 2019, out of the 4,277,000 shares authorized for grant under the 2016 Equity Incentive Plan, 3,129,000 stock options and RSUs were outstanding. As of May 31, 2018, out of the 4,718,000 shares authorized for grant under the 2016 Equity Incentive Plan, 2,906,000 stock options and RSUs were outstanding.

EMPLOYEE STOCK PURCHASE PLAN: In October 2006, the Company’s shareholders approved the 2006 Employee Stock Purchase Plan. In October 2016, the Company’s shareholders approved the Company’s Amended and Restated 2006 Employee Stock Purchase Plan (the “Purchase Plan”), which amended and restated the 2006 Employee Stock Purchase Plan. The Purchase Plan extended the term of the 2006 Employee Stock Purchase Plan indefinitely. See the Company’s Registration Statement on Form S-8 filed with the Securities and Exchange Commission on November 14, 2016 and November 21, 2018 for further information regarding the Purchase Plan. The Purchase Plan has consecutive, overlapping, twenty-four month offering periods. Each twenty-four-month offering period includes four six-month purchase periods. The offering periods generally begin on the first trading day on or after April 1 and October 1 each year. All employees who work a minimum of 20 hours per week and are customarily employed by the Company (or an affiliate thereof) for at least five months per calendar year are eligible to participate. Under the Purchase Plan, shares are purchased through employee payroll deductions at exercise prices equal to 85% of the lesser of the fair market value of the Company’s common stock at either the first day of an offering period or the last day of the purchase period. If a participant’s rights to purchase stock under all employee stock purchase plans of the Company accrue at a rate which exceeds $25,000 worth of stock for a calendar year, such participant may not be granted an option to purchase stock under the Purchase Plan. The maximum number of shares a participant may purchase during a single purchase period is 3,000 shares. In October 2018, the Company’s shareholders approved an amendment to the Purchase Plan to increase the number of shares authorized for issuance thereunder by an additional 350,000 shares of the Company’s common stock. After such amendment, a total of 1,850,000 shares of the Company’s common stock have been authorized for issuance under the Purchase Plan. During the fiscal years ended May 31, 2019, 2018 and 2017, ESPP purchase rights of 379,000, 359,000, and 1,000 shares, respectively, were granted. For the fiscal years ended May 31, 2019, 2018 and 2017, approximately 125,000, 237,000 and 151,000 shares of common stock, respectively, were issued under the Purchase Plan. As of May 31, 2019, a total of 1,481,000 shares have been issued under the Purchase Plan, and 369,000 ESPP shares remain available for issuance. |

11. EMPLOYEE BENEFIT PLANS | 11. EMPLOYEE BENEFIT PLANS: EMPLOYEE STOCK OWNERSHIP PLAN: The Company has a non-contributory, trusteed employee stock ownership plan for full-time employees who have completed three consecutive months of service and for part-time employees who have completed one year of service and have attained an age of 21. The Company can contribute either shares of the Company’s stock or cash to the plan. The contribution is determined annually by the Company and cannot exceed 15% of the annual aggregate salaries of those employees eligible for participation in the plan. On May 31, 2007, the Company converted the Aehr Test Systems Employee Stock Bonus Plan into the Aehr Test Systems Employee Stock Ownership Plan (the “Plan”). The stock bonus plan was converted to an employee stock ownership plan (“ESOP”) to enable the Plan to better comply with changes in the law regarding Company stock. Individuals’ account balances vest at a rate of 20% per year commencing upon completion of two years of service. Non-vested balances, which are forfeited following termination of employment, are allocated to the remaining employees in the Plan. Under the Plan provisions, each employee who reaches age fifty-five (55) and has been a participant in the Plan for ten years will be offered an election each year to direct the transfer of up to 25% of his/her ESOP account to the employee self-directed account in the Savings and Retirement Plan. For anyone who met the above prerequisites, the first election to diversify holdings was offered after May 31, 2008. In the sixth year, employees will be able to diversify up to 50% of their ESOP accounts. Contributions of $60,000 per year were authorized for the plan during fiscal 2019, 2018 and 2017. The contribution amounts are recorded as compensation expense, in the period authorized and included in accrued expenses, in the period authorized. Contributions of 23,000 shares were made to the ESOP during fiscal 2019 for fiscal 2018. Contributions of 13,000 shares were made to the ESOP during fiscal 2018 for fiscal 2017. Contributions of 59,000 shares were made to the ESOP during fiscal 2017 for fiscal 2016. The contribution for fiscal 2019 will be made in fiscal 2020. Shares held in the ESOP are included in the EPS calculation. 401(K) PLAN: The Company maintains a defined contribution savings plan (the “401(k) Plan”) to provide retirement income to all qualified employees of the Company. The 401(k) Plan is intended to be qualified under Section 401(k) of the Internal Revenue Code of 1986, as amended. The 401(k) Plan is funded by voluntary pre-tax contributions from employees. Contributions are invested, as directed by the participant, in investment funds available under the 401(k) Plan. The Company is not required to make, and did not make, any contributions to the 401(k) Plan during fiscal 2019, 2018 and 2017. |

13. PRODUCT WARRANTIES | 13. PRODUCT WARRANTIES: The Company provides for the estimated cost of product warranties at the time revenues are recognized on the products shipped. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from the Company’s estimates, revisions to the estimated warranty liability would be required. The standard warranty period is one year for systems and ninety days for parts and service. Following is a summary of changes in the Company’s liability for product warranties during the fiscal years ended May 31, 2019 and 2018 (in thousands): May 31, 2019 2018 Balance at the beginning of the year $ 135 $ 113 Accruals for warranties issued during the year 214 329 Consumption of reserves (195 ) (307 ) Balance at the end of the year $ 154 $ 135 The accrued warranty balance is included in accrued expenses on the consolidated balance sheets. |

17. COMMITMENTS AND CONTINGENCIES | 17. COMMITMENTS AND CONTINGENCIES: COMMITMENTS The Company leases most of its manufacturing and office space under operating leases. The Company entered into non-cancelable operating lease agreements for its United States manufacturing and office facilities and maintains equipment under non-cancelable operating leases in Germany. The Company’s principal administrative and production facilities are located in Fremont, California, in a 51,289 square foot building. The Company’s lease was renewed in February 2018 and expires in July 2023. The Company’s facility in Japan is located in a 418 square foot office in Tokyo under a cancellable lease which expires in June 2022. The Company also maintains a 1,585 square foot warehouse in Yamanashi under a lease which expires in May 2020. The Company leases a 492 square foot sales and support office in Utting, Germany. The lease, which began February 1, 1992 and expires on January 31, 2021, contains an automatic twelve months renewal, at rates to be determined, if no notice is given prior to six months from expiry. Under the lease agreements, the Company is responsible for payments of utilities, taxes and insurance. Minimum annual rentals payments under non-cancellable operating leases in each of the next five fiscal years and thereafter are as follows (in thousands): Years Ending May 31, 2020 $ 762 2021 766 2022 772 2023 795 2024 133 Thereafter — Total $ 3,228 Rental expense for the fiscal years ended May 31, 2019, 2018 and 2017 was $787,000, $587,000 and $509,000, respectively. At both May 31, 2019 and 2018, the Company had restricted cash of $80,000 held by a financial institution, representing a security deposit for its United States manufacturing and office space lease. This amount is included in other assets on the consolidated balance sheets. PURCHASE OBLIGATIONS The Company has purchase obligations to certain suppliers. In some cases the products the Company purchases are unique and have provisions against cancellation of the order. At May 31, 2019, the Company had $2,525,000 of purchase obligations which are due within the following 12 months. This amount does not include contractual obligations recorded on the consolidated balance sheets as liabilities. CONTINGENCIES The Company may, from time to time, be involved in legal proceedings arising in the ordinary course of business. While there can be no assurances as to the ultimate outcome of any litigation involving the Company, management does not believe any pending legal proceedings will result in judgment or settlement that will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows. In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, with respect to certain matters, for example, including against losses arising from a breach of representations or covenants, or from intellectual property infringement or other claims. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, payments made by the Company under these agreements have not had a material impact on the Company’s operating results, financial position or cash flows. |

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |

Accounting Policies [Abstract] | |
BUSINESS: | BUSINESS: Aehr Test Systems (the “Company”) was incorporated in California in May 1977 and primarily designs, engineers and manufactures test and burn-in equipment used in the semiconductor industry. The Company’s principal products are the Advanced Burn-In and Test System, or ABTS, the FOX full wafer contact parallel test and burn-in systems, the MAX burn-in system, WaferPak full wafer contactor, the DiePak carrier and test fixtures. |
LIQUIDITY: | LIQUIDITY: Since inception, the Company has incurred substantial cumulative losses and negative cash flows from operations. In response, the Company took steps to minimize expense levels, entered into credit arrangements, and raised capital through public and private equity offerings, to increase the likelihood that it will have sufficient cash to support operations. At May 31, 2019, the Company had $5.4 million in cash and cash equivalents. The Company anticipates that the existing cash balance together with income from operations, collections of existing accounts receivable, revenue from our existing backlog of products, the sale of inventory on hand, and deposits and down payments against significant orders will be adequate to meet its working capital and capital equipment requirements. We believe our existing cash and cash equivalents will be sufficient to meet our anticipated cash needs over the next 12 months. Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, the timing and cost of establishing additional sales and marketing capabilities, the timing and cost to introduce new and enhanced products and the timing and cost to implement new manufacturing technologies. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. Any additional debt financing obtained by us in the future could also involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. Additionally, if we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to grow or support our business and to respond to business challenges could be significantly limited. |
CONSOLIDATION: | CONSOLIDATION: The consolidated financial statements include the accounts of the Company and both its wholly-owned and majority-owned foreign subsidiaries. Intercompany accounts and transactions have been eliminated. |
FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS: | FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS: Assets and liabilities of the Company’s foreign subsidiaries and a branch office are translated into U.S. Dollars from their functional currencies of Japanese Yen, Euros and New Taiwan Dollars using the exchange rate in effect at the balance sheet date. Additionally, their net sales and expenses are translated using exchange rates approximating average rates prevailing during the fiscal year. Translation adjustments that arise from translating their financial statements from their local currencies to U.S. Dollars are accumulated and reflected as a separate component of shareholders’ equity (deficit). Transaction gains and losses that arise from exchange rate changes denominated in currencies other than the local currency are included in the Consolidated Statements of Operations as incurred. See Note 12 for the detail of foreign exchange transaction gains and losses for all periods presented. |
USE OF ESTIMATES: | USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates in the Company’s consolidated financial statements include allowance for doubtful accounts, valuation of inventory at the lower of cost or market, and warranty reserves. |
CASH EQUIVALENTS: | CASH EQUIVALENTS: Cash equivalents consist of money market instruments purchased with an original maturity of three months or less. These investments are reported at fair value. |
ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS: | ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS: Accounts receivable are derived from the sale of products throughout the world to semiconductor manufacturers, semiconductor contract assemblers, electronics manufacturers and burn-in and test service companies. Accounts receivable are recorded at the invoiced amount and are not interest bearing. The Company maintains an allowance for doubtful accounts to reserve for potentially uncollectible trade receivables. The Company also reviews its trade receivables by aging category to identify specific customers with known disputes or collection issues. The Company exercises judgment when determining the adequacy of these reserves as the Company evaluates historical bad debt trends, general economic conditions in the United States and internationally, and changes in customer financial conditions. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received. No significant adjustments to the allowance for doubtful accounts were recorded during the fiscal years ended May 31, 2019, 2018 or 2017. |
CONCENTRATION OF CREDIT RISK: | CONCENTRATION OF CREDIT RISK: The Company sells its products primarily to semiconductor manufacturers in North America, Asia, and Europe. As of May 31, 2019, approximately 49%, 25% and 26% of gross accounts receivable were from customers located in North America, Asia and Europe, respectively. As of May 31, 2018, approximately 55%, 45% and 0% of gross accounts receivable were from customers located in North America, Asia, and Europe, respectively. Three customers accounted for 44%, 25% and 21% of gross accounts receivable as of May 31, 2019. Three customers accounted for 38%, 32% and 11% of gross accounts receivable as of May 31, 2018. Four customers accounted for 36%, 14%, 12% and 10% of net sales in fiscal 2019. Three customers accounted for 34%, 26% and 13% of net sales in fiscal 2018. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company uses letter of credit terms for some of its international customers. The Company’s cash and cash equivalents are generally deposited with major financial institutions in the United States, Japan, Germany and Taiwan. The Company invests its excess cash in money market funds and U.S. Treasury securities. The money market funds bear the risk associated with each fund. The money market funds have variable interest rates. The Company has not experienced any material losses on its money market funds or short-term cash deposits. |
CONCENTRATION OF SUPPLY RISK: | CONCENTRATION OF SUPPLY RISK: The Company relies on subcontractors to manufacture many of the components and subassemblies used in its products. Quality or performance failures of the Company’s products or changes in its manufacturers’ financial or business condition could disrupt the Company’s ability to supply quality products to its customers and thereby have a material and adverse effect on its business and operating results. Some of the components and technologies used in the Company’s products are purchased and licensed from a single source or a limited number of sources. The loss of any of these suppliers may cause the Company to incur additional transition costs, result in delays in the manufacturing and delivery of its products, or cause it to carry excess or obsolete inventory and could cause it to redesign its products. |
INVENTORIES: | INVENTORIES: Inventories include material, labor and overhead, and are stated at the lower of cost (first-in, first-out method) or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less costs of completion, disposal and transportation. Provisions for excess, obsolete and unusable inventories are made after management’s evaluation of future demand and market conditions. The Company adjusts inventory balances to approximate the lower of its manufacturing costs or net realizable value. If actual future demand or market conditions become less favorable than those projected by management, additional inventory write-downs may be required, and would be reflected in cost of sales in the period the revision is made. |
PROPERTY AND EQUIPMENT: | PROPERTY AND EQUIPMENT: Property and equipment are stated at cost less accumulated depreciation and amortization. Major improvements are capitalized, while repairs and maintenance are expensed as incurred. Leasehold improvements are amortized over the lesser of their estimated useful lives or the term of the related lease. Furniture and fixtures, machinery and equipment, and test equipment are depreciated on a straight-line basis over their estimated useful lives. The ranges of estimated useful lives are generally as follows: Furniture and fixtures 2 to 6 years Machinery and equipment 3 to 6 years Test equipment 4 to 6 years |
REVENUE RECOGNITION: | REVENUE RECOGNITION: In May 2014, the FASB issued FASB ASC Topic 606, Revenue from Contracts with Customers Revenue Recognition The adoption of ASC 606 did not have a material impact on our consolidated financial statements as of June 1, 2018. No adjustment was recorded to accumulated deficit as of the adoption date and reported revenue would not have been different under legacy GAAP. Additionally, we do not expect the adoption of the revenue standard to have a material impact to our net income on an ongoing basis. We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors. We consider revenue to be earned when all of the following criteria are met: ● We have a contract with a customer that creates enforceable rights and obligations, ● Promised performance obligations are identified, ● The transaction price, or the amount we expect to receive, is determinable and ● We have satisfied the performance obligations to the customer. Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services. |
PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE: | PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE: Costs incurred in the research and development of new products or systems are charged to operations as incurred. Costs incurred in the development of software programs for the Company’s products are charged to operations as incurred until technological feasibility of the software has been established. Generally, technological feasibility is established when the software module performs its primary functions described in its original specifications, contains features required for it to be usable in a production environment, is completely documented and the related hardware portion of the product is complete. After technological feasibility is established, any additional costs are capitalized. Capitalization of software costs ceases when the software is substantially complete and is ready for its intended use. Capitalized costs are amortized over the estimated life of the related software product using the greater of the units of sales or straight-line methods over ten years. No system software development costs were capitalized or amortized in fiscal 2019, 2018 and 2017. |
IMPAIRMENT OF LONG-LIVED ASSETS: | IMPAIRMENT OF LONG-LIVED ASSETS: In the event that facts and circumstances indicate that the carrying value of assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset would be compared to the asset’s carrying value to determine if a write-down is required. |
ADVERTISING COSTS: | ADVERTISING COSTS: The Company expenses all advertising costs as incurred and the amounts were not material for all periods presented. |
SHIPPING AND HANDLING OF PRODUCTS: | SHIPPING AND HANDLING OF PRODUCTS: Amounts billed to customers for shipping and handling of products are included in net sales. Costs incurred related to shipping and handling of products are included in cost of sales. |
INCOME TAXES: | INCOME TAXES: Income taxes have been provided using the liability method whereby deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and net operating loss and tax credit carryforwards measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse or the carryforwards are utilized. Valuation allowances are established when it is determined that it is more likely than not that such assets will not be realized. A full valuation allowance was established against all deferred tax assets, as management determined that it is more likely than not that deferred tax assets will not be realized, as of May 31, 2019 and 2018. The Company accounts for uncertain tax positions consistent with authoritative guidance. The guidance prescribes a “more likely than not” recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not expect any material change in its unrecognized tax benefits over the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes. Although the Company files U.S. federal, various state, and foreign tax returns, the Company’s only major tax jurisdictions are the United States, California, Germany and Japan. Tax years 1996 – 2018 remain subject to examination by the appropriate governmental agencies due to tax loss carryovers, research and development tax credits, or other tax attributes from those years. |
COMPREHENSIVE (LOSS) INCOME: | COMPREHENSIVE (LOSS) INCOME: Comprehensive (loss) income generally represents all changes in shareholders’ equity except those resulting from investments or contributions by shareholders. Unrealized gains and losses on foreign currency translation adjustments are included in the Company’s components of comprehensive (loss) income, which are excluded from net (loss) income. Comprehensive (loss) income is included in the statements of comprehensive (loss) income. |
RECENT ACCOUNTING PRONOUNCEMENTS: | RECENT ACCOUNTING PRONOUNCEMENTS: Accounting Standards Adopted Revenue Recognition In May 2014, the FASB issued Accounting Standards Codification (“ASC”) Update No. 2014-09, Revenue from Contracts with Customers The Company adopted ASC 606 on June 1, 2018, the first day of fiscal 2019, using the modified retrospective method. The Company applied ASC 606 to all contracts not completed as of the date of adoption in order to determine any adjustment to the opening balance of retained earnings. Under the modified retrospective adoption method, the comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods, ASC 605, " Revenue Recognition The adoption of ASC 606 did not have a material impact on the Company’s consolidated financial statements as of June 1, 2018. No adjustment was recorded to accumulated deficit as of the adoption date and reported revenue would not have been different under legacy GAAP. Additionally, the Company does not expect the adoption of the revenue standard to have a material impact to the Company’s net income on an ongoing basis. Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued authoritative guidance related to the classification of certain cash receipts and cash payments on the statement of cash flows. The Company adopted this new standard in fiscal year 2019. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Intra-Entity Asset Transfers In October 2016, the FASB issued an accounting standard update that requires recognition of the income tax consequences of intra-entity transfers of assets (other than inventory) at the transaction date. The Company adopted this new standard in fiscal year 2019. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Restricted Cash. In November 2016, the FASB issued authoritative guidance related to statements of cash flows. This guidance clarifies that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts shown on the statement of cash flows. The Company adopted this new standard in fiscal year 2019. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. Income Taxes On December 22, 2017, the US government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the US tax code including but not limited to (1) reducing the US federal corporate tax rate from 34% to 21%; (2) requiring companies to pay a one-time transition tax on certain repatriated earnings of foreign subsidiaries; (3) generally eliminating US federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in US federal income of certain earnings of controlled foreign corporations; (5) creating a new limitation on deductible interest expense; (6) changing rules related to the uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017, and (7) repealing the corporate alternative minimum tax regime, or AMT, effective December 31, 2017 and permitting existing minimum tax credits to offset the regular tax liability for any tax year. Consequently, the Company has accounted for the reduction of $6.4 million of deferred tax assets with an offsetting adjustment to the valuation allowance for the fiscal year ended 2018, and recorded a benefit of $90,000 for the Company’s Federal refundable AMT credit. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. There are also certain transitional impacts of the Tax Act. As part of the transition to the new territorial tax system, the Tax Act imposes a one-time repatriation tax on deemed repatriation of historical earnings of foreign subsidiaries. The Company is not subject to the transition tax. The one-time transition tax is based on post-1986 earnings and profits that were previously deferred from U.S. income tax. The Company has finalized its calculation of the total post-1986 earnings and profits for its foreign corporations. Based on the Company’s net operating loss carryovers and valuation allowance, there is no impact to its consolidated financial statements as a result of the completion of the analysis. Accounting Standards Not Yet Adopted Financial Instruments In January 2016, the FASB issued an accounting standard update related to recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, it clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This standard is effective for us in fiscal year 2020. Early adoption is permitted. The Company does not expect a material impact of this new guidance on its consolidated financial statements. In June 2016, the FASB issued an accounting standard update that requires measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2021 on a modified retrospective basis, and early adoption in fiscal 2020 is permitted. The Company does not expect a material impact of this accounting standard update on its consolidated financial statements. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases |
