Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	These consolidated condensed financial statements include the accounts of Kulicke and Soffa Industries, Inc. and its subsidiaries (“we,” “us,” “our,” or the “Company”) with appropriate elimination of intercompany balances and transactions. The interim consolidated condensed financial statements are unaudited and, in management's opinion, include all adjustments (consisting only of normal and recurring adjustments) necessary for a fair statement of results for these interim periods. The interim consolidated condensed financial statements do not include all of the information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and 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 October 2, 2021, filed with the Securities and Exchange Commission, which includes Consolidated Balance Sheets as of October 2, 2021 and October 3, 2020, and the related Consolidated Statements of Operations, Statements of Comprehensive Income, Changes in Shareholders' Equity and Cash Flows for each of the years in the three-year period ended October 2, 2021. The results of operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for a full year.
Fiscal Year	Fiscal Year Each of the Company's first three fiscal quarters end on the Saturday that is 13 weeks after the end of the immediately preceding fiscal quarter. The fourth quarter of each fiscal year ends on the Saturday closest to September 30. Fiscal 2022 quarters end on January 1, 2022, April 2, 2022, July 2, 2022 and October 1, 2022. In fiscal years consisting of 53 weeks, the fourth quarter will consist of 14 weeks. Fiscal 2021 quarters ended on January 2, 2021, April 3, 2021, July 3, 2021 and October 2, 2021.
Nature of business	Nature of Business The Company designs, manufactures and sells capital equipment and tools as well as services, maintains, repairs and upgrades equipment, all used to assemble semiconductor devices. The Company's operating results depend upon the capital and operating expenditures of semiconductor device manufacturers, integrated device manufacturers (“IDMs”), outsourced semiconductor assembly and test providers (“OSATs”), and other electronics manufacturers including automotive electronics suppliers worldwide which, in turn, depend on the current and anticipated market demand for semiconductors and products utilizing semiconductors. The semiconductor industry is highly volatile and experiences downturns and slowdowns which can have a severe negative effect on the semiconductor industry's demand for semiconductor capital equipment, including assembly equipment manufactured and sold by the Company and, to a lesser extent, tools, including those sold by the Company. These downturns and slowdowns have in the past adversely affected the Company's operating results. The Company believes such volatility will continue to characterize the industry and the Company's operations in the future.
Use of Estimates	Use of Estimates The preparation of consolidated condensed financial statements requires management to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, net revenue and expenses during the reporting periods, and disclosures of contingent assets and liabilities as of the date of the consolidated condensed financial statements. On an ongoing basis, management evaluates estimates, including but not limited to, those related to accounts receivable, reserves for excess and obsolete inventory, carrying value and lives of fixed assets, goodwill and intangible assets, the valuation estimates and assessment of impairment and observable price adjustments, income taxes, equity-based compensation expense, and warranties. Management bases its estimates on historical experience and on various other assumptions believed to be reasonable. As a result, management makes judgments regarding the carrying values of the Company's assets and liabilities that are not readily apparent from other sources. Authoritative pronouncements, historical experience and assumptions are used as the basis for making estimates, and on an ongoing basis, management evaluates these estimates. Actual results may differ from these estimates. Due to the coronavirus (“COVID-19”) pandemic and macroeconomic headwinds, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of July 2, 2022. While there was no material impact to our consolidated condensed financial statements as of and for the quarter ended July 2, 2022, these estimates may change, as new events occur and additional information is obtained, as well as other factors related to COVID-19 and macroeconomic headwinds that could materially impact our consolidated condensed financial statements in future reporting periods.
Contract assets	Contract Assets A contract asset is the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer. ASC 606, Revenue from Contracts with Customers, distinguishes between a contract asset and a receivable based on whether receipt of the consideration is conditional on something other than the passage of time. When the Company transfers control of goods or services to a customer before the customer pays consideration, the Company records either a contract asset or a receivable depending on the nature of the Company’s right to consideration for its performance. The point at which a contract asset becomes an account receivable may be earlier than the point at which an invoice is issued. The Company assesses a contract asset for impairment in accordance with ASC 310, Receivables.
Accelerated share repurchase	Accelerated Share Repurchase From time to time, the Company may enter into accelerated share repurchase (“ASR”) agreements with third-party financial institutions to repurchase shares of the Company’s common stock. Under an ASR agreement, in exchange for an up-front payment, the counterparty makes an initial delivery of shares of the Company's common stock during the purchase period of the relevant ASR. This initial delivery of shares represents the minimum number of shares that the Company may receive under an ASR agreement. Upon settlement of an ASR agreement, the counterparty may deliver additional shares, with the final number of shares delivered determined based on the volume-weighted average price of the Company’s common stock over the term of such ASR agreement, less an agreed-upon discount. The transactions are accounted for as equity transactions and are included in Treasury Stock when the shares are received, at which time there is an immediate reduction in the weighted-average common shares calculation for basic and diluted earnings per share.
Recent accounting pronouncements	Recent Accounting Pronouncements Income Taxes In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Income Taxes (Topic 740). The amendments in this ASU, among other changes, simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, clarify and amend the existing guidance. We adopted this ASU in the first quarter of fiscal 2022. The adoption of this ASU did not have a material impact on our consolidated condensed financial statements. Contracts in Entity's Own Equity In August 2020, the FASB issued ASU 2020-06, Derivatives and Hedging - Contracts in Entity's Own Equity (Topic 815). The amendments in this ASU, among other changes, remove current guidance that allows an entity to rebut the presumption that potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares if the entity has a history or policy of cash settlement. These amendments affect any instrument that may be settled in cash or shares and, therefore, affects the diluted earnings per share calculation for both convertible instruments and contracts in an entity's own equity. We elected to early adopt this ASU in the second quarter of fiscal 2022. The adoption of this ASU did not have a material impact on our consolidated condensed financial statements. Codification Improvements In October 2020, the FASB issued ASU 2020-10, Codification Improvements. The amendments in this ASU affect a wide variety of topics in the Codification and improve the consistency of the Codification by including all disclosure guidance in the appropriate disclosure sections (Section 50). We adopted this ASU in the first quarter of fiscal 2022. The adoption of this ASU did not have a material impact on our consolidated condensed financial statements.
