Accounting Policies [Abstract] | |
1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCCOUNTING POLICIES | 1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCCOUNTING POLICIES The accompanying financial information has been prepared by Aehr Test Systems, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the unaudited condensed consolidated financial statements for the interim periods presented have been prepared on a basis consistent with the May 31, 2019 audited consolidated financial statements and reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated financial position and results of operations as of and for such periods indicated. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended May 31, 2019. Results for the interim periods presented herein are not necessarily indicative of results which may be reported for any other interim period or for the entire fiscal year. PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company"). All significant intercompany balances have been eliminated in consolidation. For the Company’s majority owned subsidiary, Aehr Test Systems Japan K.K., the noncontrolling interest of the portion the Company does not own was reflected on the Condensed Consolidated Balance Sheets in Shareholders’ Equity and in the Condensed Consolidated Statements of Operations. ACCOUNTING ESTIMATES. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Estimates are used to account for sales and revenue allowances, the allowance for doubtful accounts, inventory valuations, income taxes, stock-based compensation expenses, and product warranties, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES. The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended May 31, 2019. There have been no significant changes in the Company’s significant accounting policies during the three and six months ended November 30, 2019, except for the adoption of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Update No. 2016-02, Leases, as discussed in Note “2. RECENT ACCOUNTING PRONOUNCEMENTS.” |

New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
2. RECENT ACCOUNTING PRONOUNCEMENTS | 2. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted Financial Instruments In January 2016, the FASB issued an accounting standard update related to the recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments and financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, this standard clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Company adopted this new standard in fiscal year 2020. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. Leases In February 2016, the FASB issued ASC Update No. 2016-02, Leases (FASB ASC Topic 842, Leases). The Company adopted the standard as of June 1, 2019, using the modified retrospective approach and the transition method provided by ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, the Company applied the new leasing rules on the date of adoption and recognized the cumulative effect of initially applying the standard as an adjustment to its opening balance sheet, rather than at the earliest comparative period presented in the financial statements. Prior periods presented are in accordance with the previous lease guidance under FASB ASC Topic 840, Leases. In addition, the Company applied the package of practical expedients permitted under FASB ASC Topic 842 transition guidance to its entire lease portfolio at June 1, 2019. As a result, the Company was not required to reassess (i) whether any expired or existing contracts are or contain leases, (ii) the classification of any expired or existing leases and (iii) the treatment of initial direct costs for any existing leases. Furthermore, the Company elected not to separate lease and non-lease components for the majority of its leases. Instead, for all applicable classes of underlying assets, the Company accounted for each separate lease component and the non-lease components associated with that lease component as a single lease component. As a result of adopting FASB ASC Topic 842, Leases on June 1, 2019, the Company recognized right-of-use assets of $2.7 million and corresponding liabilities of $2.8 million for its existing operating lease portfolio on its unaudited condensed consolidated balance sheet. Operating lease right-of-use assets are presented within Operating lease right-of-use assets and corresponding liabilities are presented within Operating lease liabilities, short-term and Operating lease liabilities, long-term on the Company’s unaudited condensed consolidated balance sheet. There was no material impact to the Company’s unaudited condensed consolidated statements of operations or unaudited condensed consolidated statements of cash flows. Please refer to Note “11. LEASES” for information regarding the Company’s lease portfolio as of November 30, 2019 as accounted for under FASB ASC Topic 842, Leases. Accounting Standards Not Yet Adopted Financial Instruments In June 2016, the FASB issued an accounting standard update (“ASU”) 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. Due to a subsequent ASU in November 2019, the accounting standard will be effective for the Company beginning in the first quarter of fiscal 2024 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 on its consolidated financial statements. |

Revenue from Contract with Customer [Abstract] | |
3. REVENUE | 3. 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 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): Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Type of good / service: Systems $ 3,027 $ 3,712 $ 5,961 $ 5,518 Contactors 3,046 943 4,696 2,096 Services 801 1,256 1,750 3,037 $ 6,874 $ 5,911 $ 12,407 $ 10,651 Product lines: Wafer-level $ 6,335 $ 4,226 $ 11,161 $ 6,195 Test During Burn-In 539 1,685 1,246 4,456 $ 6,874 $ 5,911 $ 12,407 $ 10,651 The following presents information about the Company’s operations in different geographic areas. Net sales are based upon ship-to location (in thousands): Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Geographic region: United States $ 2,627 $ 4,509 $ 7,684 $ 7,204 Asia 3,529 1,334 3,867 3,068 Europe 718 68 856 379 $ 6,874 $ 5,911 $ 12,407 $ 10,651 With the exception of the amount of service contracts and extended warranties, the Company’s product category revenues are recognized at the point in time when control transfers to customers. Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Timing of revenue recognition: Products and services transferred at a point in time $ 6,322 $ 5,272 $ 11,181 $ 9,390 Services transferred over time 552 639 1,226 1,261 $ 6,874 $ 5,911 $ 12,407 $ 10,651 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 November 30, 2019 and May 31, 2019 were $1,873,000 and $1,734,000, respectively. During the three and six months ended November 30, 2019, the Company recognized $132,000 and $1,181,000, respectively, of revenues that were included in contract liabilities as of May 31, 2019. Remaining performance obligations On November 30, 2019, the Company had $415,000 of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 50% of its remaining performance obligations as revenue in fiscal 2020, and an additional 50% 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] | |
4. EARNINGS PER SHARE | 4. EARNINGS PER SHARE Basic earnings per share is determined using the weighted average number of common shares outstanding during the period. Diluted earnings per share 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): Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Numerator: Net income (loss) $ 251 $ (629 ) $ (162 ) $ (2,144 ) Denominator for basic net income (loss) per share: Weighted average shares outstanding 22,823 22,294 22,765 22,242 Shares used in basic net income (loss) per share calculation 22,823 22,294 22,765 22,242 Effect of dilutive securities 89 — — — Denominator for diluted net income (loss) per share 22,912 22,294 22,765 22,242 Basic net income (loss) per share $ 0.01 $ (0.03 ) $ (0.01 ) $ (0.10 ) Diluted net income (loss) per share $ 0.01 $ (0.03 ) $ (0.01 ) $ (0.10 ) 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 antidilutive. Stock options to purchase 2,919,000 shares of common stock were outstanding as of November 30, 2019, but were not included in the computation of diluted net income per share, because the inclusion of such shares would be antidilutive. In the three months ended November 30, 2018 and six months ended November 30, 2019 and 2018, potential common shares were not included in the calculation of diluted net loss per share as the effect would be antidilutive. 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 3,373,000 shares of common stock, RSUs for 38,000 shares and ESPP rights to purchase 327,000 ESPP shares were outstanding as of November 30, 2018, but were not included in the computation of diluted net loss per share because the inclusion of such shares would be antidilutive. The 2,657,000 shares convertible under the 9% Convertible Secured Notes (the “Convertible Notes”) outstanding at November 30, 2018 were not included in the computation of diluted net loss per share because the inclusion of such shares would be antidilutive. |

Fair Value Disclosures [Abstract] | |
5. FAIR VALUE OF FINANCIAL INSTRUMENTS | 5. 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 November 30, 2019 (in thousands): Balance as of November 30, 2019 Level 1 Level 2 Level 3 Money market funds $ 1,838 $ 1,838 $ — $ — Assets $ 1,838 $ 1,838 $ — $ — 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 $ — $ — Included in Money market funds as of November 30, 2019 and May 31, 2019 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 November 30, 2019 and May 31, 2019. There were no transfers between Level 1 and Level 2 fair value measurements during the three and six months ended November 30, 2019. 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. |

Product Warranties Disclosures [Abstract] | |
8. PRODUCT WARRANTIES | 8. 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. The following is a summary of changes in the Company's liability for product warranties during the three and six months ended November 30, 2019 and 2018 (in thousands): Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Balance at the beginning of the period $ 192 $ 160 $ 154 $ 135 Accruals for warranties issued during the period 79 71 141 146 Consumption of reserves (81 ) (68 ) (105 ) (118 ) Balance at the end of the period $ 190 $ 163 $ 190 $ 163 The accrued warranty balance is included in accrued expenses on the accompanying condensed consolidated balance sheets. |

Income Tax Disclosure [Abstract] | |
10. INCOME TAXES | 10. 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. Since fiscal 2009, a full valuation allowance was established against all deferred tax assets as management determined that it is more likely than not that certain deferred tax assets will not be realized. 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. |

Leases [Abstract] | |
11. LEASES | 11. LEASES The Company has only operating leases for real estate including corporate offices, warehouse space and certain equipment. A lease with an initial term of 12 months or less is generally not recorded on the condensed consolidated balance sheet, unless the arrangement includes an option to purchase the underlying asset, or renew the arrangement that the Company is reasonably certain to exercise (short-term leases). The Company recognizes lease expense on a straight-line basis over the lease term for short-term leases that the Company does not record on its balance sheet. The Company’s operating leases have remaining lease terms of 1 to 4 years. The Company determines whether an arrangement is or contains a lease based on the unique facts and circumstances present at the inception of the arrangement. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term at an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received. The weighted-average remaining lease term for the Company’s operating leases was 3.7 years at November 30, 2019 and the weighted-average discount rate was 5.5%. The Company’s operating lease cost was $183,000 and $366,000 for the three and six months ended November 30, 2019, respectively. The following table presents supplemental cash flow information related to the Company’s operating leases (in thousands): Three Months Ended Six Months Ended November 30, 2019 November 30, 2019 Cash paid for amounts included in the measurement of operating lease liabilities Operating cash flows from operating leases $ 184 $ 366 The following table presents the maturities of the Company’s operating lease liabilities as of November 30, 2019 (in thousands): Fiscal year Operating Leases 2020 (excluding the first six months of 2020) $ 366 2021 754 2022 772 2023 795 2024 132 Thereafter — Total future minimum operating lease payments $ 2,819 Less: imputed interest 276 Present value of operating lease liabilities $ 2,543 |

Share-based Payment Arrangement [Abstract] | |
12. STOCK-BASED COMPENSATION | 12. STOCK-BASED COMPENSATION Stock-based compensation expense consists of expenses for stock options, restricted stock units, or RSUs, and employee stock purchase plan, or ESPP, purchase rights. 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 cost 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 an equity instrument. See Note 10 in the Company’s Annual Report on Form 10-K for fiscal 2019 filed on August 28, 2019 for further information regarding the 2016 Equity Incentive Plan and the Amended and Restated 2006 ESPP. The following table summarizes the stock-based compensation expense for the three and six months ended November 30, 2019 and 2018 (in thousands): Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Stock-based compensation in the form of employee stock options, RSUs and Cost of sales $ 19 $ 23 $ 39 $ 59 Selling, general and administrative 135 136 264 284 Research and development 51 65 101 137 Total stock-based compensation $ 205 $ 224 $ 404 $ 480 As of November 30, 2019 and 2018, there were no stock-based compensation expenses capitalized as part of inventory. During the three months ended November 30, 2019 and 2018, the Company recorded stock-based compensation expense related to stock options and RSUs of $163,000 and $166,000, respectively. During the six months ended November 30, 2019 and 2018, the Company recorded stock-based compensation expense related to stock options and RSUs of $313,000 and $339,000, respectively. As of November 30, 2019, the total compensation expense related to unvested stock-based awards under the Company’s 2016 Equity Incentive Plan, but not yet recognized, was approximately $1,405,000, which is net of estimated forfeitures of $4,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 3.0 years. During the three months ended November 30, 2019 and 2018, the Company recorded stock-based compensation expense related to the ESPP of $42,000 and $58,000, respectively. During the six months ended November 30, 2019 and 2018, the Company recorded stock-based compensation expense related to the ESPP of $91,000 and $141,000, respectively. As of November 30, 2019, the total compensation expense related to purchase rights under the ESPP but not yet recognized was approximately $117,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 0.9 years. Valuation Assumptions Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model 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 four or 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 model 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 value of the Company’s stock options granted to employees for the three and six months ended November 30, 2019 and 2018 were estimated using the following weighted average assumptions in the Black-Scholes option valuation model: Three Months Ended Six Months Ended November 30, November 30, 2019 2018 2019 2018 Expected term (in years) 5 5 5 5 Volatility 0.72 0.70 0.71 0.72 Risk-free interest rate 1.60% 3.01% 1.85% 2.84% Weighted average grant date fair value $ 1.05 $ 1.21 $ 0.98 $ 1.38 The fair values of the ESPP purchase rights granted for the three and six months ended November 30, 2019 were estimated using the following weighted-average assumptions: Three and Six Months Ended November 30, 2019 Expected term (in years) 0.5-2.0 Volatility 0.62-0.71 Expected dividend $ 0.00 Risk-free interest rates 1.56% - 1.81% Estimated forfeiture rate 0% Weighted average grant date fair value $ 0.80 During the three and six months ended November 30, 2019, ESPP purchase rights of 38,000 were granted. During the three and six months ended November 30, 2018, ESPP purchase rights of 327,000 were granted. Total ESPP shares issued during the three and six months ended November 30, 2019 and 2018 were 71,000 and 64,000 shares, respectively. As of November 30, 2019, there were 299,000 ESPP shares available for issuance.

The accompanying financial information has been prepared by Aehr Test Systems, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the unaudited condensed consolidated financial statements for the interim periods presented have been prepared on a basis consistent with the May 31, 2019 audited consolidated financial statements and reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated financial position and results of operations as of and for such periods indicated. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended May 31, 2019. Results for the interim periods presented herein are not necessarily indicative of results which may be reported for any other interim period or for the entire fiscal year. |
PRINCIPLES OF CONSOLIDATION | PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company"). All significant intercompany balances have been eliminated in consolidation. For the Company’s majority owned subsidiary, Aehr Test Systems Japan K.K., the noncontrolling interest of the portion the Company does not own was reflected on the Condensed Consolidated Balance Sheets in Shareholders’ Equity and in the Condensed Consolidated Statements of Operations. |
ACCOUNTING ESTIMATES | ACCOUNTING ESTIMATES. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Estimates are used to account for sales and revenue allowances, the allowance for doubtful accounts, inventory valuations, income taxes, stock-based compensation expenses, and product warranties, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates. |

New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
RECENT ACCOUNTING PRONOUNCEMENTS | 2. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Standards Adopted Financial Instruments In January 2016, the FASB issued an accounting standard update related to the recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments and financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, this standard clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Company adopted this new standard in fiscal year 2020. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. Leases In February 2016, the FASB issued ASC Update No. 2016-02, Leases (FASB ASC Topic 842, Leases). The Company adopted the standard as of June 1, 2019, using the modified retrospective approach and the transition method provided by ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, the Company applied the new leasing rules on the date of adoption and recognized the cumulative effect of initially applying the standard as an adjustment to its opening balance sheet, rather than at the earliest comparative period presented in the financial statements. Prior periods presented are in accordance with the previous lease guidance under FASB ASC Topic 840, Leases. In addition, the Company applied the package of practical expedients permitted under FASB ASC Topic 842 transition guidance to its entire lease portfolio at June 1, 2019. As a result, the Company was not required to reassess (i) whether any expired or existing contracts are or contain leases, (ii) the classification of any expired or existing leases and (iii) the treatment of initial direct costs for any existing leases. Furthermore, the Company elected not to separate lease and non-lease components for the majority of its leases. Instead, for all applicable classes of underlying assets, the Company accounted for each separate lease component and the non-lease components associated with that lease component as a single lease component. As a result of adopting FASB ASC Topic 842, Leases on June 1, 2019, the Company recognized right-of-use assets of $2.7 million and corresponding liabilities of $2.8 million for its existing operating lease portfolio on its unaudited condensed consolidated balance sheet. Operating lease right-of-use assets are presented within Operating lease right-of-use assets and corresponding liabilities are presented within Operating lease liabilities, short-term and Operating lease liabilities, long-term on the Company’s unaudited condensed consolidated balance sheet. There was no material impact to the Company’s unaudited condensed consolidated statements of operations or unaudited condensed consolidated statements of cash flows. Please refer to Note “11. LEASES” for information regarding the Company’s lease portfolio as of November 30, 2019 as accounted for under FASB ASC Topic 842, Leases. Accounting Standards Not Yet Adopted Financial Instruments In June 2016, the FASB issued an accounting standard update (“ASU”) 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. Due to a subsequent ASU in November 2019, the accounting standard will be effective for the Company beginning in the first quarter of fiscal 2024 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 on its consolidated financial statements. |
