Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
The Company and Significant Accounting Policies | The Company and Significant Accounting Policies The Company Alpha and Omega Semiconductor Limited and its subsidiaries (the “Company”, "AOS", "we" or "us") design, develop and supply a broad range of power semiconductors. The Company's portfolio of products targets high-volume applications, including personal computers, flat panel TVs, LED lighting, smart phones, battery packs, quick chargers, home appliances, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment. The Company conducts its operations primarily in the United States of America (“USA”), Hong Kong, China, and South Korea. Basis of Preparation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Securities and Exchange Commission Regulation S-X, as amended. They do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019 . All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the results of operations for the periods presented have been included in the interim periods. Operating results for the six months ended December 31, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2020 or any other interim period. The condensed consolidated balance sheet at June 30, 2019 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019 . During the six months ended December 31, 2019 , the Company corrected the prior year amount of property and equipment purchased but not yet paid in the supplemental disclosures of non-cash investing and financing information by decreasing it by $31.3 million , from $61.6 million to $30.3 million . This disclosure change had no effect on the consolidated statements of operations and cash flows for the six months ended December 31, 2018. Leases On July 1, 2019, the Company adopted Topic 842, Leases, using the modified retrospective method. Results for reporting periods beginning after July 1, 2019 were presented under Topic 842, while prior period amounts were not adjusted and continue to be reported in accordance with the historical accounts under Topic 840. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and long-term operating lease liabilities on the Company's condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and long-term finance leases liabilities on the condensed consolidated balance sheets. The Company elected the practical expedient permitted under the transition guidance, which allowed the Company to carryforward its historical lease classification, the Company's assessment on whether a contract was or contains a lease, and its initial direct costs for any leases that existed prior to July 1, 2019. The Company elected to combine its lease and non-lease components as a single lease component for all asset classes. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company uses an estimate of its incremental borrowing rate based on the information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating lease expense is generally recognized on a straight-line basis over the lease term. Variable lease payments are expensed as incurred and are not included within the operating lease ROU asset and lease liability calculation. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less. See Note 6 for further details. Joint Venture In March 2016, the Company executed an agreement with two strategic investment funds owned by the Municipality of Chongqing, China (the "Chongqing Funds") to form a joint venture, (the "JV Company"), for a new state-of-the-art power semiconductor packaging, testing and wafer fabrication facility in Liangjiang New Area of Chongqing (the "Joint Venture"). As of December 31, 2019 , the Company owns 51% , and the Chongqing Funds own 49% of the equity interest in the JV Company. The Joint Venture is accounted for under the provisions of the consolidation guidance since the Company has a controlling financial interest. The JV Company has continued ramping up its production of assembly and testing during the six months ended December 31, 2019. In July 2019, we commenced limited mass production at the 12-inch wafer fabrication facility, and continued ramping up during the six months ended December 31, 2019. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. To the extent there are material differences between these estimates and actual results, the Company's condensed consolidated financial statements will be affected. On an ongoing basis, the Company evaluates the estimates, judgments and assumptions including those related to stock rotation returns, price adjustments, allowance for doubtful accounts, inventory reserves, warranty accrual, income taxes, leases, share-based compensation, and useful lives for property, plant and equipment and intangible assets. Share-based Compensation Expense The Company recognizes expense related to share-based compensation awards that are ultimately expected to vest based on estimated fair values on the date of grant. The fair value of restricted share units is based on the market value of the Company's common share on the date of grant. For restricted stock awards subject to market conditions, the fair value of each restricted stock award is estimated at the date of grant using the Monte-Carlo pricing model. The fair value of stock options is estimated on the date of grant using the Black-Scholes option valuation model. Share-based compensation expense is recognized on the accelerated attribution basis, net of estimated forfeitures, over the requisite service period of the award, which generally equals the vesting period. Restricted Cash As a condition of the loan agreement, the Company is required to keep a compensating balance at the issuing bank (see Note 5). In addition, the Company also maintained restricted cash in connection with cash balances temporarily restricted for regular business operations including a dispute case with a vendor. These balances have been excluded from the Company’s cash and cash equivalents balance and are classified as restricted cash in the Company’s consolidated balance sheets. As of December 31, 2019 and June 30, 2019, the amount of restricted cash was $4.2 million and $2.4 million , respectively. Fair Value of Financial Instruments The fair value of cash equivalents is based on observable market prices and have been categorized in Level 1 in the fair value hierarchy. Cash equivalents consist primarily of short term bank deposits. The carrying values of financial instruments such as cash and cash equivalents, accounts receivable and accounts payable approximate their carrying values due to their short-term maturities. The carrying value of the company's debt is considered a reasonable estimate of fair value which is estimated by considering the current rates available to the Company for debt of the same remaining maturities, structure and terms of the debts. Comprehensive Income (Loss) Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company's accumulated other comprehensive income (loss) consists of cumulative foreign currency translation adjustments. Total comprehensive income (loss) is presented in the condensed consolidated statements of comprehensive income (loss). Recent Accounting Pronouncements Recently Issued Accounting Standards not yet adopted In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12") by removing certain exceptions to the general principles. The amendments will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments is permitted. Depending on the amendment, adoption may be applied on a retrospective, modified retrospective or prospective basis. We are currently evaluating the impacts of adoption of the new guidance to our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". These amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contact with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. ASU 2018-15 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact that adoption of this guidance will have on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13”). ASU 2018-13 amends existing fair value measurement disclosure requirements by adding, changing, or removing certain disclosures. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. ASU No. 2018-13 is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses ("ASU 2016-13"). This accounting standard update changes the accounting for recognizing impairments of financial assets. Under the update, credit losses for certain types of financial instruments will be estimated based on expected losses. The update also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact of this accounting standard update on its Consolidated Financial Statements. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance requires a dual approach for lessee accounting under which a lessee accounts for leases as finance leases or operating leases. Both finance and operating leases result in the lessee recognizing a right-of-use asset and a corresponding liability on its balance sheet, with differing methodology for income statement recognition. The Company adopted this standard as of July 1, 2019, using the modified retrospective transition method and recorded a cumulative-effect balance sheet adjustment. As a result of adopting ASU 2016-02 on July 1, 2019, the Company recognized operating lease right-of-use assets and corresponding operating lease liabilities of approximately $21 million each from existing leases on the Company's condensed consolidated balance sheet. See Note 6 for further details. In June 2018, the FASB issued ASU 2018-07, "Compensation -Stock Compensation: Improvement to Nonemployees Share-Based Payment Accounting ("ASU 2018-07"), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. ASU 2018-07 had no material impact on the Company's consolidated financial statements. |

Risks and Uncertainties [Abstract] | |
Concentration of Credit Risk and Significant Customers | Concentration of Credit Risk and Significant Customers The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application and review of credit approvals, credit ratings and other monitoring procedures. In some instances, the Company also obtains letters of credit from certain customers. Credit sales, which are mainly on credit terms of 30 to 60 days , are only made to customers who meet the Company's credit requirements, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company considers its trade accounts receivable to be of good credit quality because its key distributors and direct customers have long-standing business relationships with the Company and the Company has not experienced any significant write-offs of accounts receivable in the past. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, when available. The Company ships its product indirectly to Huawei and its affiliates (collectively, “Huawei”) through distributors. Typically, the Company sells its products to distributors who then sell to original design manufacturers (“ODM’s”) that incorporate our products into end applications that are then shipped to Huawei. While distributor point of sale reports summarize distributor sales to ODM’s, the Company must make certain assumptions and estimates in order to determine the amount of revenues attributed to indirect shipment to Huawei. During the fiscal year ended June 30, 2019, the estimated revenues attributed to indirect shipment to Huawei were approximately 2% of total revenues. During the period from May 2019 to December 2019, estimated revenues earned by the Company from shipments indirectly made to Huawei were in the range of $11 million to $13 million . See Note 10. Summarized below are individual customers whose revenue or accounts receivable balances were more than 10% of the respective total consolidated amounts: Three Months Ended December 31, Six Months Ended December 31, Percentage of revenue 2019 2018 2019 2018 Customer A 31.3 % 30.6 % 30.0 % 29.1 % Customer B 37.0 % 37.6 % 36.0 % 37.8 % December 31, June 30, Percentage of accounts receivable Customer A 14.0 % 12.1 % Customer B 39.9 % 19.7 % Customer C * 18.1 % Customer D * 13.3 % * Less than 10% |

Under the Agreements, at the end of the five-year lease term, the Lenders agree to sell such equipment back to the JV Company for a nominal amount (RMB 1 ). The JV Company’s obligations under the Lease Financing are secured by the land and building owned by the JV Company (the “Collateral”). The proceeds from the Lease Financing will be used primarily for the acquisition and installation of the 12-inch fabrication equipment and other expenses of the JV Company relating to the completion of the fabrication facility located in Chongqing. The Agreements contain customary representation, warranties and covenants, including restrictions on the transfer of the Collateral. The Agreements also contain customary events of default, including but not limited to, failure to make payments and breach of material terms under the Agreements.

The interest is required to be paid on March 21 and September 21 each year. As of December 31, 2019, the outstanding balance of the loan was $24.0 million . On March 12, 2019, the JV Company entered into a loan agreement with The Export-Import Bank of China in the aggregate principal amount of 200 million RMB (approximately $29.8 million based on currency exchange rate between RMB and U.S. Dollar on March 31, 2019).

In December 2019, 3.0 million RMB was repaid. As of December 31, 2019 , the outstanding balance of the loan was 197 million RMB (equivalent of $28.2 million based on the currency exchange rate as of December 31, 2019 ). On May 1, 2018, Jireh Semiconductor Incorporated ("Jireh"), a wholly-owned subsidiary of the Company, entered into a loan agreement with a financial institution (the "Bank") that provided a term loan in the amount of $17.8 million . The obligation under the loan agreement is secured by certain real estate assets of Jireh and guaranteed by the Company. The loan has a five-year term and matures on June 1, 2023. Beginning June 1, 2018, Jireh made consecutive monthly payments of principal and interest to the Bank. The outstanding principal shall accrue interest at a fixed rate of 5.04% per annum on the basis of a 360-day year.

Leases [Abstract] | |
Leases | Leases Under Topic 842, the Company evaluates contracts for lease accounting at contract inception and assesses lease classification at the lease commencement date. Operating leases are included in operating lease right-of-use ("ROU") assets, operating lease liabilities and operating lease liabilities - long-term on the Company's consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and finance lease liabilities-long-term on the consolidated balance sheets. The Company recognizes an ROU asset and corresponding lease obligation liability at the lease commencement date where the lease obligation liability is measured at the present value of the minimum lease payments. As most of the leases do not provide an implicit rate, the Company uses its incremental borrowing rate at lease commencement. The Company uses an interest rate commensurate with the interest rate to borrow on a collateralized basis over a similar term with an amount equal to the lease payments. Operating leases are primarily related to offices, research and development facilities, sales and marketing facilities, and manufacturing facilities. In addition, long-term supply agreements to lease gas tank equipment and purchase industrial gases are accounted for as operating leases. Lease agreements frequently include renewal provisions and require the Company to pay real estate taxes, insurance and maintenance costs. For operating leases, the amortization of the ROU asset and the accretion of its lease obligation liability result in a single straight-line expense recognized over the lease term. The finance lease is related to the RMB 400.0 million of lease financing with YinHai Leasing Company and China Import/Export Bank in the JV Company. See Note 5 - Bank Borrowings for details. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less.

Operating leases are included in operating lease right-of-use ("ROU") assets, operating lease liabilities and operating lease liabilities - long-term on the Company's consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and finance lease liabilities-long-term on the consolidated balance sheets. The Company recognizes an ROU asset and corresponding lease obligation liability at the lease commencement date where the lease obligation liability is measured at the present value of the minimum lease payments. As most of the leases do not provide an implicit rate, the Company uses its incremental borrowing rate at lease commencement. The Company uses an interest rate commensurate with the interest rate to borrow on a collateralized basis over a similar term with an amount equal to the lease payments. Operating leases are primarily related to offices, research and development facilities, sales and marketing facilities, and manufacturing facilities. In addition, long-term supply agreements to lease gas tank equipment and purchase industrial gases are accounted for as operating leases. Lease agreements frequently include renewal provisions and require the Company to pay real estate taxes, insurance and maintenance costs. For operating leases, the amortization of the ROU asset and the accretion of its lease obligation liability result in a single straight-line expense recognized over the lease term. The finance lease is related to the RMB 400.0 million of lease financing with YinHai Leasing Company and China Import/Export Bank in the JV Company. See Note 5 - Bank Borrowings for details. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less. The components of the Company’s operating and finance lease expenses are as follows for the period presented (in thousands): Six Months Ended December 31, 2019 Operating Leases: Fixed rent expense $ 2,614 Variable rent expense 421 Finance Lease: Amortization of equipment 1,716 Interest 1,457 Short-term leases Short-term lease expenses 152 Total lease expenses $ 6,360 Supplemental balance sheet information related to the Company’s operating and finance leases is as follows (in thousands, except lease term and discount rate): December 31, 2019 Operating Leases : ROU assets associated with operating leases $ 18,667 Finance Lease: Property, plant and equipment, gross 105,606 Accumulated depreciation (86,806 ) Property, plant and equipment, net 18,800 Weighted average remaining lease term (in years) Operating leases 9.73 Finance lease 3.22 Weighted average discount rate Operating leases 5.29 % Finance lease 5.46 % Supplemental cash flow information related to the Company’s operating and finance lease is as follows (in thousands): Six Months Ended December 31, 2019 Cash paid from amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,541 Operating cash flows from finance lease $ 1,457 Financing cash flows from finance lease $ 3,403 Future minimum lease payments are as follows as of December 31, 2019 (in thousands): Operating Leases Finance Leases The remainder of 2020 $ 2,417 $ 9,062 2021 3,248 17,477 2022 2,716 16,622 2023 2,360 12,048 2024 1,973 — 2025 1,466 — Thereafter 10,128 — Total minimum lease payments 24,308 55,209 Less amount representing interest (5,467 ) (4,893 ) Total lease liabilities $ 18,841 $ 50,316 Prior to the adoption of the new lease standard, future minimum lease payments as of June 30, 2019 were as follows (in thousands): Year ending June 30, Operating Leases Finance Leases 2020 $ 4,357 $ 14,219 2021 1,741 17,799 2022 1,164 16,928 2023 894 12,269 2024 1,002 — Thereafter 149 — Total minimum lease payments 9,307 61,215 Less amount representing interest — (6,479 ) Total lease liabilities $ 9,307 $ 54,736 |

Share-based Payment Arrangement, Noncash Expense [Abstract] | |
Shareholders' Equity and Share-based Compensation | Shareholders' Equity and Share-based Compensation Share Repurchase In September 2017, the Board of Directors approved a new repurchase program (the “Repurchase Program”) that allowed the Company to repurchase its common shares from the open market pursuant to a pre-established Rule 10b5-1 trading plan or through privately negotiated transactions up to an aggregate of $30.0 million . The amount and timing of any repurchases under the Repurchase Program depend on a number of factors, including but not limited to, the trading price, volume, and availability of the Company's common shares. Shares repurchased under this program are accounted for as treasury shares and the total cost of shares repurchased is recorded as a reduction of shareholders' equity. From time to time, treasury shares may be reissued as part of the Company's stock-based compensation programs. Gains on re-issuance of treasury stock are credited to additional paid-in capital; losses are charged to additional paid-in capital to offset the net gains, if any, from previous sales or re-issuance of treasury stock. Any remaining balance of the losses is charged to retained earnings. During the six months ended December 31, 2019 , the Company did not repurchase any shares from the open market. Since the inception of the program, the Company repurchased an aggregate of 6,784,648 shares from the open market for a total cost of $67.3 million , at an average price of $9.92 per share, excluding fees and related expenses. No repurchased shares have been retired. Of the 6,784,648 repurchased shares, 140,328 shares with a weighted average repurchase price of $10.39 per share, were reissued at an average price of $5.50 per share pursuant to option exercises and vested restricted share units. As of December 31, 2019 , approximately $13.4 million remained available under the Repurchase Program. Time-based Restricted Stock Units ("TRSU") The following table summarizes the Company's TRSU activities for the six months ended December 31, 2019 : Number of Restricted Stock Units Weighted Average Grant Date Fair Value Per Share Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Nonvested at June 30, 2019 906,341 $ 14.09 1.62 $ 8,465,225 Granted 64,442 $ 12.24 Vested (73,312 ) $ 13.71 Forfeited (14,125 ) $ 14.12 Nonvested at December 31, 2019 883,346 $ 13.98 1.22 $ 12,031,173 Market-based Restricted Stock Units ("MSUs") During the quarter ended September 30, 2018, the Company granted 1.3 million market-based restricted stock units ("MSUs") to certain personnel. The number of shares to be earned at the end of performance period is determined based on the Company’s achievement of specified stock prices and revenue thresholds during the performance period from January 1, 2019 to December 31, 2021 as well as the recipients remaining in continuous service with the Company through such period. The MSUs vest in four equal annual installments after the end of each performance period. The Company estimated the grant date fair values of its MSUs with derived service periods of 4.5 to 7.5 years using a Monte-Carlo simulation model with the following assumptions: Risk-free interest rate of 2.7% , expected term of 3.5 years, expected volatility of 38.8% and dividend yield of 0% . The Company recorded approximately $0.1 million and $0.3 million of expenses for these MSUs during the three and six months ended December 31, 2019 , respectively, and approximately $0.2 million and $0.4 million during the three and six months ended December 31, 2018 , respectively. Performance-based Restricted Stock Units ("PRSUs") In March 2017, 2018 and 2019, the Company granted 170,000 , 298,050 and 291,750 performance-based RSUs (“PRSUs”), respectively to certain personnel. The number of shares to be earned under the PRSUs is determined based on the level of attainment of predetermined financial goals. The PRSUs vest in four equal annual installments from the first anniversary date after the grant date if certain predetermined financial goals were met. The Company recorded approximately $0.5 million and $0.7 million of expenses for these PRSUs during the three and six months ended December 31, 2019 , respectively, and approximately $0.8 million and $1.4 million during the three and six months ended December 31, 2018 , respectively. The following table summarizes the Company's PRSUs activities for the six months ended December 31, 2019 : Number of Performance-based Restricted Stock Units Weighted Average Grant Date Fair Value Per Share Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Nonvested at June 30, 2019 596,724 $ 13.95 1.88 $ 5,573,402 Forfeited (3,625 ) $ 15.11 Nonvested at December 31, 2019 593,099 $ 13.94 1.37 $ 8,078,008 Stock Options The Company did not grant any stock options during the three and six months ended December 31, 2019 and 2018. The number of options expected to vest is the result of applying the pre-vesting forfeiture rate assumption to total outstanding options. The following table summarizes the Company's stock option activities for the six months ended December 31, 2019 : Weighted Weighted Average Average Remaining Number of Exercise Price Contractual Aggregate Shares Per Share Term (in years) Intrinsic Value Outstanding at June 30, 2019 876,478 $ 10.98 3.06 $ 758,871 Exercised (2,500 ) $ 10.50 $ 4,726 Canceled or forfeited (5,000 ) $ 15.00 Outstanding at December 31, 2019 868,978 $ 10.96 2.58 $ 3,108,361 Options vested and expected to vest 868,978 $ 10.96 2.58 $ 3,108,361 Exercisable at December 31, 2019 868,978 $ 10.96 2.58 $ 3,108,361 Employee Share Purchase Plan ("ESPP") The assumptions used to estimate the fair values of common shares issued under the ESPP were as follows: Six Months Ended December 31, 2019 Volatility rate 46.4% Risk-free interest rate 1.6% Expected term 1.3 years Dividend yield 0% Share-based Compensation Expense T he total share-based compensation expense recognized in the condensed consolidated statements of operations for the periods presented was as follows: Three Months Ended December 31, Six Months Ended December 31, 2019 2018 2019 2018 (in thousands) (in thousands) Cost of goods sold $ 404 $ 541 $ 840 $ 1,038 Research and development 472 742 996 1,374 Selling, general and administrative 1,611 3,135 3,020 5,135 $ 2,487 $ 4,418 $ 4,856 $ 7,547 As of December 31, 2019 , total unrecognized compensation cost under the Company's equity plans was $9.3 million , which is expected to be recognized over a weighted-average period of 1.9 years. |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes The Company recognized income tax expense of approximately $0.6 million and $0.7 million , for the three months ended December 31, 2019 and 2018, respectively. Excluding the discrete income tax items, the effective tax rate for the three months ended December 31, 2019 and 2018 was (13.8)% . The changes in the tax expense between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year. For the six months ended December 31, 2019, the Company recognized income tax expense of approximately $1.0 million , which included a discrete tax expense of $0.03 million . For the six months ended December 31, 2018, the Company recognized income tax expense of approximately $1.3 million , which included a discrete tax expense of $0.03 million . Excluding the discrete income tax items, the estimated effective tax rate for the six months ended December 31, 2019 was (17.4)% compared to (23.7)% for the six months ended December 31, 2018. The changes in the effective tax rate and tax expense between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year. The Company files its income tax returns in the United States and in various foreign jurisdictions. The tax years 2001 to 2019 remain open to examination by U.S. federal and state tax authorities. The tax years 2012 to 2019 remain open to examination by foreign tax authorities. The Company's income tax returns are subject to examinations by the Internal Revenue Service and other tax authorities in various jurisdictions. In accordance with the guidance on the accounting for uncertainty in income taxes, the Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. As of December 31, 2019 , the gross amount of unrecognized tax benefits was approximately $7.3 million , of which $4.3 million , if recognized, would reduce the effective income tax rate in future periods. If the Company's estimate of income tax liabilities proves to be less than the ultimate assessment, then a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when the Company determines the liabilities are no longer necessary. The Company does not anticipate any material changes to its uncertain tax positions during the next twelve months. On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. In the July 2015 ruling, the Tax Court concluded that the sharing of the cost of employee stock compensation in a company’s cost-sharing arrangement was invalid under the U.S. Administrative Procedures Act. In June 2019, a panel of the Ninth Circuit of the U.S. Court of Appeals reversed this decision. In July 2019, Altera petitioned U.S. Court of Appeals for the Ninth Circuit to hold an en banc rehearing of the case. Due to the uncertainty surrounding the status of the current regulations and questions related to the scope of potential benefits, the Company has not recorded any benefit as of December 31, 2019. The Company will continue to monitor ongoing developments and potential impacts to its financial statements. |

Segment Reporting [Abstract] | |
Segment and Geographic Information | Segment and Geographic Information The Company is organized as, and operates in, one operating segment: the design, development and supply of power semiconductor products for computing, consumer electronics, communication and industrial applications. The chief operating decision-maker is the Chief Executive Officer. The financial information presented to the Company's Chief Executive Officer is on a consolidated basis, accompanied by information about revenue by customer and geographic region, for purposes of evaluating financial performance and allocating resources. The Company has one business segment, and there are no segment managers who are held accountable for operations, operating results and plans for products or components below the consolidated unit level. Accordingly, the Company reports as a single operating segment. The Company sells its products primarily to distributors in the Asia Pacific region, who in turn sell these products to end customers. Because the Company's distributors sell their products to end customers which may have a global presence, revenue by geographical location is not necessarily representative of the geographical distribution of sales to end user markets. The revenue by geographical location in the following tables is based on the country or region in which the products were shipped to: Three Months Ended December 31, Six Months Ended December 31, 2019 2018 2019 2018 (in thousands) (in thousands) Hong Kong $ 97,244 $ 87,180 $ 190,346 $ 178,771 China 16,571 24,760 33,083 45,157 South Korea 2,279 139 8,269 308 United States 898 1,967 1,999 3,940 Other countries 868 879 1,965 1,821 $ 117,860 $ 114,925 $ 235,662 $ 229,997 The following is a summary of revenue by product type: Three Months Ended December 31, Six Months Ended December 31, 2019 2018 2019 2018 (in thousands) (in thousands) Power discrete $ 101,491 $ 93,294 $ 202,032 $ 185,549 Power IC 14,655 19,384 30,379 38,799 Packaging and testing services 1,714 2,247 3,251 5,649 $ 117,860 $ 114,925 $ 235,662 $ 229,997 Long-lived assets, net consisting of property, plant and equipment and land use rights, by geographical area are as follows: December 31, June 30, (in thousands) China $ 321,256 $ 321,145 United States 93,976 87,817 Other Countries 823 775 $ 416,055 $ 409,737 |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Purchase Commitments As of December 31, 2019 and June 30, 2019 , the Company had approximately $52.0 million and $59.5 million , respectively, of outstanding purchase commitments primarily for purchases of semiconductor raw materials, wafers, spare parts and packaging and testing services, and approximately $24.3 million and $33.8 million , respectively, of capital commitments for the purchase of property and equipment and EPC construction. Other Commitments See Note 5 and Note 6 of the Notes to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q for descriptions of commitments including bank borrowings and leases . Contingencies and Indemnities The Company has in the past, and may from time to time in the future, become involved in legal proceedings arising from the normal course of business activities. The semiconductor industry is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. Irrespective of the validity of such claims, the Company could incur significant costs in the defense of such claims and suffer adverse effects on its operations. The U.S. Department of Justice recently commenced an investigation into the Company's compliance with export control regulations relating to its business transactions with Huawei and its affiliates (“Huawei”), which were added to the “Entity List” maintained by Department of Commerce (“DOC”) on May 16, 2019. The Company is cooperating fully with federal authorities in the investigation. The Company has maintained an export control compliance program and has been committed to comply fully with all applicable laws and regulations. In connection with this investigation, DOC requested the Company to suspend shipments of its products to Huawei, and the Company complied with such request. The Company is currently working with DOC to resolve this issue in order to resume shipments to Huawei. Given the case is in its early stages and still ongoing, the Company cannot estimate the reasonably possible loss or range of loss that may occur. Also, the Company is unable to predict the duration, scope, result or related costs of the investigation, although the Company expects to incur additional professional fees as a result of this matter. In addition, the Company is unable to predict, if any, further action that may be taken by the government in connection with the investigation, or what, if any, penalties, sanctions or remedial actions may be sought. The Company is a party to a variety of agreements that it has contracted with various third parties. Pursuant to these agreements, the Company may be obligated to indemnify another party to such an agreement with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold, certain intellectual property rights, specified environmental matters and certain income taxes. In these circumstances, payment by the Company is customarily conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claim. Further, the Company's obligations under these agreements may be limited in time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements. The Company has not historically paid or recorded any material indemnifications, and no accrual has been made at December 31, 2019 and June 30, 2019 . The Company has agreed to indemnify its directors and certain employees as permitted by law and pursuant to its Bye-laws, and has entered into indemnification agreements with its directors and executive officers. The Company has not recorded a liability associated with these indemnification arrangements, as it historically has not incurred any material costs associated with such indemnification obligations. Costs associated with such indemnification obligations may be mitigated by insurance coverage that the Company maintains. However, such insurance may not cover any, or may cover only a portion of, the amounts the Company may be required to pay. In addition, the Company may not be able to maintain such insurance coverage in the future. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Preparation | Basis of Preparation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Securities and Exchange Commission Regulation S-X, as amended. They do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019 . All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the results of operations for the periods presented have been included in the interim periods. Operating results for the six months ended December 31, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2020 or any other interim period. The condensed consolidated balance sheet at June 30, 2019 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2019 . |
Leases | Leases On July 1, 2019, the Company adopted Topic 842, Leases, using the modified retrospective method. Results for reporting periods beginning after July 1, 2019 were presented under Topic 842, while prior period amounts were not adjusted and continue to be reported in accordance with the historical accounts under Topic 840. The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and long-term operating lease liabilities on the Company's condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, finance lease liabilities and long-term finance leases liabilities on the condensed consolidated balance sheets. The Company elected the practical expedient permitted under the transition guidance, which allowed the Company to carryforward its historical lease classification, the Company's assessment on whether a contract was or contains a lease, and its initial direct costs for any leases that existed prior to July 1, 2019. The Company elected to combine its lease and non-lease components as a single lease component for all asset classes. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company uses an estimate of its incremental borrowing rate based on the information available at the lease commencement date. The operating lease ROU assets also include any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Operating lease expense is generally recognized on a straight-line basis over the lease term. Variable lease payments are expensed as incurred and are not included within the operating lease ROU asset and lease liability calculation. The Company does not record leases on the condensed consolidated balance sheet with a term of one year or less. See Note 6 for further details. |
Use of Estimates | Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. To the extent there are material differences between these estimates and actual results, the Company's condensed consolidated financial statements will be affected. On an ongoing basis, the Company evaluates the estimates, judgments and assumptions including those related to stock rotation returns, price adjustments, allowance for doubtful accounts, inventory reserves, warranty accrual, income taxes, leases, share-based compensation, and useful lives for property, plant and equipment and intangible assets. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The fair value of cash equivalents is based on observable market prices and have been categorized in Level 1 in the fair value hierarchy. Cash equivalents consist primarily of short term bank deposits. The carrying values of financial instruments such as cash and cash equivalents, accounts receivable and accounts payable approximate their carrying values due to their short-term maturities. The carrying value of the company's debt is considered a reasonable estimate of fair value which is estimated by considering the current rates available to the Company for debt of the same remaining maturities, structure and terms of the debts. |
Comprehensive Income (Loss) | Comprehensive Income (Loss) Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company's accumulated other comprehensive income (loss) consists of cumulative foreign currency translation adjustments. Total comprehensive income (loss) is presented in the condensed consolidated statements of comprehensive income (loss). |
Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Issued Accounting Standards not yet adopted In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12") by removing certain exceptions to the general principles. The amendments will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments is permitted. Depending on the amendment, adoption may be applied on a retrospective, modified retrospective or prospective basis. We are currently evaluating the impacts of adoption of the new guidance to our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract". These amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contact with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. ASU 2018-15 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted. The Company is currently assessing the impact that adoption of this guidance will have on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13”). ASU 2018-13 amends existing fair value measurement disclosure requirements by adding, changing, or removing certain disclosures. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. ASU No. 2018-13 is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial position, results of operations or cash flows. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses ("ASU 2016-13"). This accounting standard update changes the accounting for recognizing impairments of financial assets. Under the update, credit losses for certain types of financial instruments will be estimated based on expected losses. The update also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact of this accounting standard update on its Consolidated Financial Statements. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance requires a dual approach for lessee accounting under which a lessee accounts for leases as finance leases or operating leases. Both finance and operating leases result in the lessee recognizing a right-of-use asset and a corresponding liability on its balance sheet, with differing methodology for income statement recognition. The Company adopted this standard as of July 1, 2019, using the modified retrospective transition method and recorded a cumulative-effect balance sheet adjustment. As a result of adopting ASU 2016-02 on July 1, 2019, the Company recognized operating lease right-of-use assets and corresponding operating lease liabilities of approximately $21 million each from existing leases on the Company's condensed consolidated balance sheet. See Note 6 for further details. In June 2018, the FASB issued ASU 2018-07, "Compensation -Stock Compensation: Improvement to Nonemployees Share-Based Payment Accounting ("ASU 2018-07"), which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. ASU 2018-07 had no material impact on the Company's consolidated financial statements. |
Concentration of Credit Risk | The Company manages its credit risk associated with exposure to distributors and direct customers on outstanding accounts receivable through the application and review of credit approvals, credit ratings and other monitoring procedures. In some instances, the Company also obtains letters of credit from certain customers. Credit sales, which are mainly on credit terms of 30 to 60 days , are only made to customers who meet the Company's credit requirements, while sales to new customers or customers with low credit ratings are usually made on an advance payment basis. The Company considers its trade accounts receivable to be of good credit quality because its key distributors and direct customers have long-standing business relationships with the Company and the Company has not experienced any significant write-offs of accounts receivable in the past. The Company closely monitors the aging of accounts receivable from its distributors and direct customers, and regularly reviews their financial positions, when available. |
