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 June 30, 2024, and for the three and six months ended June 30, 2024 and 2023, contained in this Form 10-Q (the “Consolidated Financial Statements”) are unaudited pursuant to the rules and regulations of the SEC. The December 31, 2023 Consolidated Balance Sheet data contained in this Form 10-Q 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. GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations. In our opinion, the Consolidated Financial Statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods and should be read in conjunction with the financial statements included in the 2023 Form 10-K. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024. Unless the context otherwise requires, all references to “Amkor,” “we,” “us” or “our” are to Amkor Technology, Inc. and its wholly and majority-owned subsidiaries. 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 as a result of, for example, any worsening of the global business and economic environment. Leases. Total long-term finance lease liabilities as of June 30, 2024 and December 31, 2023 were $76.3 million and $47.8 million, respectively. Goodwill. The balance of goodwill in the Consolidated Balance Sheets contained in this Form 10-Q reflects adjustments for foreign currency translation. Unbilled Receivables . Total unbilled receivables as of June 30, 2024 and December 31, 2023 were $218.5 million and $260.8 million, respectively. Contract Liabilities. Contract liabilities were $110.0 million and $135.5 million as of June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024 and December 31, 2023, the short-term portions of the liabilities were $63.6 million and $71.1 million, respectively. The remainder of the June 30, 2024 contract liability balance is expected to be recognized in revenue over the next 1-5 years. Revenue recognized during the six months ended June 30, 2024 and 2023 that was included in the contract liabilities balance at the beginning of the period was $37.0 million and $39.2 million, respectively. Share-based compensation. In February 2024, long-term incentive awards were granted in the form of time-vested restricted stock units (“RSUs”) and performance-vested restricted stock units (“PSUs”) to our management pursuant to the 2021 Equity Plan with different terms from those issued in prior years. For a description of the RSUs and PSUs granted in prior years, please refer to our Consolidated Financial Statements in Part II, Item 8, Note 2 of the 2023 Form 10-K. The RSUs granted in the first quarter of 2024 will generally vest in three equal installments on the anniversary of the grant date, subject to the recipient’s continued employment with the Company at the time of vesting. The value of the RSUs is determined based on the fair market value of the underlying shares on the date of the grant, reduced by the present value of dividends or dividend equivalent rights expected to be paid on our common stock prior to vesting. The PSUs granted in the first quarter of 2024 are divided between PSUs based on earnings per share in each of 2024, 2025 and 2026 (“EPS PSUs”), and PSUs based on relative total shareholder return (“rTSR PSUs”), compared to the components of the PHLX Semiconductor Index (the “SOX”) over a three-year period, with half of the awards as EPS PSUs and half as rTSR PSUs. For the EPS PSUs, the value is determined based on the fair market value of the underlying shares on the date of the grant, reduced by the present value of dividends or dividend equivalent rights expected to be paid on our common stock prior to vesting. The number of shares of our common stock to be received annually at vesting will range from 0% to 225%. For the rTSR PSUs, the Company estimated the grant-date fair value of the PSUs subject to a market condition using a Monte Carlo simulation model, using the following weighted-average assumptions: risk-free interest rate of 4.33% and annualized volatility of 46.77%. The grant date fair value of the PSUs was $27.07. The number of shares of our common stock to be received at vesting will range from 0% to 150% of the target grant amount based on rTSR performance over the three-year performance period. The Company recognizes the grant date fair value of the PSUs as compensation expense ratably over the vesting period. Recently Issued Standards. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires disclosure of additional income tax information, primarily related to effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Adoption of this ASU should be applied on a prospective basis, but retrospective application is permitted. The new standard will result in enhanced disclosures in our financial statements. |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes Income tax expense of $26.5 million for the six months ended June 30, 2024 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 recent results of 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 increased from $31.5 million as of December 31, 2023 to $32.2 million as of June 30, 2024. 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.

In May 2024, we replaced this loan by entering into a ₩80.0 billion (approximately $59 million) term loan agreement with the option to borrow and re-borrow the funds up to six times per year through May 2027. Principal is payable at maturity, and interest is payable monthly, at a fixed rate of 3.95%. During the six months ended June 30, 2024, we borrowed $58.7 million, which we immediately repaid. As of June 30, 2024, ₩80.0 billion, or approximately $58 million, was available to be drawn. (2) We entered into various short-term term loans which mature semiannually.

From time to time, Amkor Technology, Inc., ATT, AATT, and ATSH guarantee certain debt of our subsidiaries. The agreements governing our indebtedness contain affirmative and negative covenants which restrict our ability to pay dividends and could restrict our operations. These restrictions are determined in part by calculations based upon cumulative net income and do not currently have a material impact on our ability to make dividend payments or stock repurchases.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivatives | Derivatives We use foreign currency forward contracts to mitigate foreign currency risk of certain monetary assets and 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. In April 2024, we started to hedge certain net investment positions in foreign subsidiaries by entering into foreign currency forward contracts, generally settled monthly, that are designated as hedges of net investments. The difference between the forward rate and the spot rate of the net investment hedge forward contracts is excluded from the assessment of hedge effectiveness and subsequently reported in other (income) expense, net on a straight-line basis over the life of the forward contracts. Changes in the fair value of the forward contracts are recognized in other comprehensive income (loss) within foreign currency translation. As of June 30, 2024 and December 31, 2023, our foreign exchange forward contracts consisted of the following: June 30, 2024 December 31, 2023 Notional Value Fair Value (Level 2) Balance Sheet Location Notional Value Fair Value (Level 2) Balance Sheet Location (In thousands) Forward contracts not designated as hedging instruments Japanese yen $ 198,258 $ (1,534) Accrued expenses $ 279,027 $ 2,745 Other current assets Korean won 76,373 303 Other current assets 59,036 (97) Accrued expenses Philippine peso 7,149 (5) Accrued expenses 6,553 (20) Accrued expenses Singapore dollar 7,373 (11) Accrued expenses 11,506 20 Other current assets Taiwan dollar 40,535 58 Other current assets 37,914 89 Other current assets Total forward contracts not designated as hedging instruments $ 329,688 $ (1,189) $ 394,036 $ 2,737 June 30, 2024 December 31, 2023 Notional Value Fair Value (Level 2) Balance Sheet Location Notional Value Fair Value (Level 2) Balance Sheet Location (In thousands) Forward contracts designated as net investment hedging instruments Japanese yen $ 121,436 $ 935 Other current assets $ — $ — N/A Total forward contracts designated as net investment hedging instruments $ 121,436 $ 935 $ — $ — For the three and six months ended June 30, 2024, the derivatives not designated as hedging instruments resulted in a net loss of $19.1 million and $46.6 million, respectively, which were nearly offset by the foreign currency gains associated with the underlying net liabilities. For the three and six months ended June 30, 2023, the derivatives not designated as hedging instruments resulted in a net loss of $26.4 million and $38.4 million, respectively, which were partially offset by the foreign currency gains associated with the underlying net liabilities. |

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 measure the fair value of our debt for disclosure purposes. The following table presents the fair value of our debt: June 30, 2024 December 31, 2023 Fair Value Carrying Value Fair Value Carrying Value (In thousands) Senior notes (Level 1) $ 526,580 $ 522,220 $ 531,778 $ 521,839 Revolving credit facilities and term loans (Level 2) 567,385 581,503 666,316 681,617 Total debt $ 1,093,965 $ 1,103,723 $ 1,198,094 $ 1,203,456 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 determine 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. Attorney fees related to legal matters are expensed as incurred. Lease Commitments As of June 30, 2024 we have entered into additional lease agreements that have not yet commenced of approximately $61 million. |

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires disclosure of additional income tax information, primarily related to effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Adoption of this ASU should be applied on a prospective basis, but retrospective application is permitted. The new standard will result in enhanced disclosures in our financial statements. |
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 recent results of 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.
