Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Interim Financial Statements | Interim Financial Statements Basis of Presentation. The Consolidated Financial Statements and related disclosures as of March 31, 2021, and for the three months ended March 31, 2021 and 2020, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2020 Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S.”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, these financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods. These financial statements should be read in conjunction with the financial statements included in our Annual Report for the year ended December 31, 2020, filed on Form 10-K with the SEC on February 19, 2021. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year. Unless the context otherwise requires, all references to “Amkor,” “we,” “us” or “our” are to Amkor Technology, Inc. and our subsidiaries. Certain prior year amounts have been reclassified to conform to current year presentation. Use of Estimates. The Consolidated Financial Statements have been prepared in conformity with U.S. GAAP, using management’s best estimates and judgments where appropriate. These estimates and judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The estimates and judgments will also affect the reported amounts for certain revenues and expenses during the reporting period. Actual results could differ materially from these estimates and judgments, including the impact of Covid-19 and any worsening of the global business and economic environment. Goodwill. The balance of goodwill in our Consolidated Balance Sheets reflects adjustments for foreign currency translation. Unbilled Receivables . Total unbilled receivables as of March 31, 2021 and December 31, 2020 were $142.7 million and $146.8 million, respectively. Contract Liability. Contract liabilities were $53.3 million and $51.6 million as of March 31, 2021 and December 31, 2020, respectively. As of March 31, 2021 and December 31, 2020, the short-term portion of the liability was $34.9 million and $30.3 million, respectively. Revenue recognized during the three months ended March 31, 2021 and 2020 that was included in the contract liability balance at the beginning of the period was $8.1 million and $5.3 million, respectively. |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes Income tax expense of $11.7 million for the three months ended March 31, 2021 reflects income taxes, foreign withholding taxes and minimum taxes. We monitor on an ongoing basis our ability to utilize our deferred tax assets and whether there is a need for a related valuation allowance. In evaluating our ability to recover our deferred tax assets in the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. We maintain a valuation allowance on certain U.S. and foreign deferred tax assets. Such valuation allowances are released as the related tax benefits are realized or when sufficient evidence exists to conclude that it is more likely than not that the deferred tax assets will be realized. Unrecognized tax benefits represent reserves for potential tax deficiencies or reductions in tax benefits that could result from federal, state or foreign tax audits. Gross unrecognized tax benefits decreased from $32.6 million at December 31, 2020 to $29.1 million as of March 31, 2021, primarily due to the lapse of statutes of limitations and settlement of examinations offset by increases related to income attribution. All of our unrecognized tax benefits would reduce our effective tax rate if recognized. Our unrecognized tax benefits are subject to change for effective settlement of examinations, changes in the recognition threshold of tax positions, the expiration of statutes of limitations and other factors. |

Earnings Per Share [Abstract] | |
Earnings Per Share | Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amkor common stockholders by the weighted-average number of common shares outstanding during the period. The weighted-average number of common shares outstanding is reduced for treasury stock. Diluted EPS is computed based on the weighted-average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding stock options, performance-vested restricted stock units, time-vested restricted stock units and unvested restricted shares. The following table summarizes the computation of basic and diluted EPS: For the Three Months Ended March 31, 2021 2020 (In thousands, Net income attributable to Amkor common stockholders $ 119,809 $ 63,889 Weighted-average number of common shares outstanding - basic 243,267 240,919 Effect of dilutive securities: Share-based awards 1,862 414 Weighted-average number of common shares outstanding - diluted 245,129 241,333 Net income attributable to Amkor per common share: Basic $ 0.49 $ 0.27 Diluted 0.49 0.26 The following table summarizes the potential shares of common stock that were excluded from diluted EPS because the effect of including these potential shares was anti-dilutive: For the Three Months Ended March 31, 2021 2020 (In thousands) Share-based awards — 4,321 |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivatives | Derivatives We use foreign currency forward contracts to mitigate foreign currency risk of certain assets and monetary liabilities denominated in foreign currencies. We do not enter into such contracts for trading or speculative purposes. These derivative instruments are not designated as hedging instruments. As of March 31, 2021 and December 31, 2020, our foreign exchange forward contracts consisted of the following: March 31, 2021 December 31, 2020 Notional Value Fair Value (Level 2) Balance Sheet Location Notional Value Fair Value (Level 2) Balance Sheet Location (In thousands) Japanese Yen $ 369,619 $ (3,923) Accrued expenses $ 465,192 $ 1,279 Other current assets Korean Won 160,490 35 Other current assets 161,612 190 Other current assets Philippine Peso 9,183 (23) Accrued expenses 10,974 (7) Accrued expenses Total forward contracts $ 539,292 $ (3,911) $ 637,778 $ 1,462 For the three months ended March 31, 2021 and 2020, the derivatives resulted in a net loss of $34.9 million and $1.2 million respectively.

Fair Value Measurements
Fair Value Measurements | 3 Months Ended |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements The accounting framework for determining fair value includes a hierarchy for ranking the quality and reliability of the information used to measure fair value, which enables the reader of the financial statements to assess the inputs used to develop those measurements. The fair value hierarchy consists of three tiers as follows: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data. For our Level 2 short-term investments, we consider factors such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, obtained from quoted market prices and independent pricing vendors, to determine the fair value of these assets and liabilities. The fair values of cash, accounts receivable, trade accounts payable, capital expenditures payable, and certain other current assets and accrued expenses, approximate carrying values because of their short-term nature. The carrying value of certain other non-current assets and liabilities approximates fair value. Our assets and liabilities recorded at fair value on a recurring basis include restricted cash money market funds and short-term investments, including investments classified as cash equivalents. Cash equivalent money market funds and restricted cash money market funds are invested in U.S. money market funds and various U.S. and foreign bank operating and time deposit accounts, which are due on demand or carry a maturity date of less than three months when purchased. No restrictions have been imposed on us regarding withdrawal of balances with respect to our cash equivalents as a result of liquidity or other credit market issues affecting the money market funds we invest in or the counterparty financial institutions holding our deposits. Our derivative financial instruments are valued using quoted market prices for similar assets. Counterparties to these derivative contracts are highly rated financial institutions. We also measure certain assets and liabilities, including property, plant and equipment and goodwill, at fair value on a nonrecurring basis. We also review goodwill for impairment annually during the fourth quarter of each year. We measure the fair value of our debt for disclosure purposes. The following table presents the fair value of financial instruments that are not recorded at fair value on a recurring basis: March 31, 2021 December 31, 2020 Fair Value Carrying Value Fair Value Carrying Value (In thousands) Senior notes (Level 1) $ 567,656 $ 519,957 $ 570,339 $ 519,803 Revolving credit facilities and term loans (Level 2) 575,898 567,814 647,557 634,543 Total debt $ 1,143,554 $ 1,087,771 $ 1,217,896 $ 1,154,346 The estimated fair value of our senior notes is based primarily on quoted market prices reported on or near the respective balance sheet dates. The estimated fair value of our revolving credit facilities and term loans is calculated using a discounted cash flow analysis, which utilizes market-based assumptions including forward interest rates adjusted for credit risk. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies We generally warrant that our services will be performed in a professional and workmanlike manner and in compliance with our customers’ specifications. We accrue costs for known warranty issues. Historically, our warranty costs have been immaterial. Legal Proceedings We are involved in claims and legal proceedings and may become involved in other legal matters arising in the ordinary course of our business. We evaluate these claims and legal matters on a case-by-case basis to make a determination as to the impact, if any, on our business, liquidity, results of operations, financial condition or cash flows. Although the outcome of these matters is uncertain, we believe that the ultimate outcome of these claims and proceedings, individually and in the aggregate, will not have a material adverse impact to us. Our evaluation of the potential impact of these claims and legal proceedings on our business, liquidity, results of operations, financial condition or cash flows could change in the future. In accordance with the accounting guidance for loss contingencies, including legal proceedings, lawsuits, pending claims and other legal matters, we accrue for a loss contingency when we conclude that the likelihood of a loss is probable and the amount of the loss can be reasonably estimated. We adjust our accruals from time to time as we receive additional information, but the loss we incur may be significantly greater than or less than the amount we have accrued. We disclose loss contingencies if we believe they are material and there is at least a reasonable possibility that a loss has been incurred.

Basis of Presentation | Basis of Presentation. The Consolidated Financial Statements and related disclosures as of March 31, 2021, and for the three months ended March 31, 2021 and 2020, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2020 Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S.”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, these financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods. These financial statements should be read in conjunction with the financial statements included in our Annual Report for the year ended December 31, 2020, filed on Form 10-K with the SEC on February 19, 2021. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year. Unless the context otherwise requires, all references to “Amkor,” “we,” “us” or “our” are to Amkor Technology, Inc. and our subsidiaries. |
Reclassifications | Certain prior year amounts have been reclassified to conform to current year presentation. |
Use of Estimates | Use of Estimates. The Consolidated Financial Statements have been prepared in conformity with U.S. GAAP, using management’s best estimates and judgments where appropriate. These estimates and judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The estimates and judgments will also affect the reported amounts for certain revenues and expenses during the reporting period. Actual results could differ materially from these estimates and judgments, including the impact of Covid-19 and any worsening of the global business and economic environment. |
Goodwill | Goodwill. The balance of goodwill in our Consolidated Balance Sheets reflects adjustments for foreign currency translation. |
Income Taxes | We monitor on an ongoing basis our ability to utilize our deferred tax assets and whether there is a need for a related valuation allowance. In evaluating our ability to recover our deferred tax assets in the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. We maintain a valuation allowance on certain U.S. and foreign deferred tax assets. Such valuation allowances are released as the related tax benefits are realized or when sufficient evidence exists to conclude that it is more likely than not that the deferred tax assets will be realized. |
Commitments and Contingencies | In accordance with the accounting guidance for loss contingencies, including legal proceedings, lawsuits, pending claims and other legal matters, we accrue for a loss contingency when we conclude that the likelihood of a loss is probable and the amount of the loss can be reasonably estimated. We adjust our accruals from time to time as we receive additional information, but the loss we incur may be significantly greater than or less than the amount we have accrued. We disclose loss contingencies if we believe they are material and there is at least a reasonable possibility that a loss has been incurred.
