Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Entegris, Inc. (“Entegris”, “the Company”, “us”, “we”, or “our”) is a leading supplier of advanced materials and process solutions for the semiconductor and other high-technology industries. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, particularly receivables, inventories, property, plant and equipment, right-of-use assets, goodwill, intangibles, accrued expenses, short-term and long-term lease liability, income taxes and related accounts, and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Basis of Presentation The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and contain all adjustments considered necessary, and are of a normal recurring nature, to present fairly the financial position as of July 3, 2021 and December 31, 2020, and the results of operations and comprehensive income for the three and six months ended July 3, 2021 and June 27, 2020, the equity statements as of and for the three and six months ended July 3, 2021 and June 27, 2020, and cash flows for the six months ended July 3, 2021 and June 27, 2020. The condensed consolidated financial statements and accompanying notes are presented as permitted by Form 10-Q and do not contain certain information included in the Company’s annual consolidated financial statements and notes. The information included in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis and consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2020. The results of operations for the three and six months ended July 3, 2021 are not necessarily indicative of the results to be expected for the full year. Fair Value of Financial Instruments The carrying value of cash equivalents, accounts receivable, accounts payable, accrued payroll and related benefits, and other accrued liabilities approximates fair value due to the short maturity of those items. The fair value of long-term debt, including current maturities, was $957.6 million at July 3, 2021, compared to the carrying amount of long-term debt, including current maturities, of $936.4 million at July 3, 2021. Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, “Simplifying the Accounting for Income Taxes” under ASC 740, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. The Company adopted this new guidance in the first quarter of fiscal 2021. The adoption of ASU 2019-12 did not have a material impact on the condensed consolidated financial statements. Recently Issued Accounting Pronouncements The Company currently has no material recent accounting pronouncements yet to be adopted.

Revenues [Abstract]
Revenue from Contract with Customer	REVENUES Revenue Recognition Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales. The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from advance payments received on sales of the Company’s products. The Company makes the required disclosures with respect to deferred revenue below. The Company does not disclose information about remaining performance obligations that have original expected durations of one year or less. Nature of goods and services The following is a description of principal activities from which the Company generates its revenues. The Company has three reportable segments. For more detailed information about reportable segments, see note 10 to the condensed consolidated financial statements. For each of the three reportable segments, the recognition of revenue regarding the nature of goods and services provided by the segments are similar and described below. The Company recognizes revenue for product sales at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment or delivery, depending on the terms of the underlying contracts. For product sales contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognizes the related revenue as control of each individual product is transferred to the customer, in satisfaction of the corresponding performance obligations. The Company generally recognizes revenue for sales of services when the Company has satisfied the performance obligation. The payment terms and revenue recognized is based on time and materials. The Company also enters into arrangements to license its intellectual property. These arrangements typically permit the customer to use a specialized manufacturing process or patented technology and in return the Company receives a royalty fee. The Company recognizes revenue for a sales-based or usage-based royalty promised in exchange for a license of intellectual property when the subsequent sale or usage occurs. The Company offers certain customers cash discounts and volume rebates as sales incentives. The discounts and volume rebates are recorded as a reduction in sales at the time revenue is recognized in an amount estimated based on historical experience and contractual obligations. The Company periodically reviews the assumptions underlying its estimates of discounts and volume rebates and adjusts its revenues accordingly. In addition, the Company offers free product rebates to certain customers. The Company utilizes an adjusted market approach to estimate the stand-alone selling price of the loyalty program and allocates a portion of the consideration received to the free product offering. The free product offering is redeemable upon future purchases of the Company’s products. The amount associated with free product rebates is recorded as deferred revenue on the balance sheet and is recognized as revenue when the free product is redeemed or when the likelihood of redemption is remote. The Company has deemed that the amount is immaterial for disclosure. The Company provides for the estimated costs of fulfilling its obligations under product warranties at the time the related revenue is recognized. The Company estimates the costs based on historical failure rates, projected repair costs, and knowledge of specific product failures (if any). The specific warranty terms and conditions vary depending upon the product sold and the country in which the Company does business, but generally include parts and labor over a period generally ranging from 90 days to one year. The Company regularly reevaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjusts the amounts as necessary. The Company’s contracts are generally short-term in nature. Most contracts’ terms do not exceed twelve months.

Business Combinations [Abstract]
Business Combination Disclosure	ACQUISITIONS During the six months ended July 3, 2021, the Company completed an acquisition for $2.5 million, substantially all of which was paid in cash and qualified as a business combination. This acquisition has been included in the Company’s condensed consolidated results of operations since its acquisition date. The effect of this business combination was not material to the Company’s condensed consolidated results of operations. Global Measurement Technologies, Inc. On July 10, 2020, the Company acquired Global Measurement Technologies, Inc., an analytical instrument provider for critical processes in semiconductor production, and its manufacturing partner Clean Room Plastics, Inc. (collectively, “GMTI”). GMTI reports into the Advanced Materials Handling segment of the Company. The acquisition was accounted for under the acquisition method of accounting, and GMTI’s results of operations are included in the Company’s condensed consolidated financial statements as of and since July 10, 2020. The acquisition does not constitute a material business combination. The purchase price for GMTI includes cash consideration of $36.3 million, net of cash acquired, which was funded from the Company’s existing cash on hand. The purchase price of GMTI exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $16.1 million. Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets. This additional investment value resulted in goodwill, which is expected to be non-deductible for income tax purposes. During the quarter ended September 26, 2020, the Company finalized its fair value determination of the assets acquired and the liabilities assumed. The following table summarizes the final allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of the acquisition: (In thousands): July 10, 2020 Trade accounts and note receivable, net $ 937 Inventories, net 1,079 Identifiable intangible assets 18,180 Right-of-use assets 337 Accounts payable and accrued liabilities (28) Short-term lease liability (150) Long-term lease liability (187) Net assets acquired 20,168 Goodwill 16,099 Total purchase price, net of cash acquired $ 36,267 The Company recognized the following finite-lived intangible assets as part of the acquisition of GMTI: (In thousands) Amount Weighted Developed technology $ 3,570 6.5 Trademarks and trade names 1,010 11.5 Customer relationships 13,600 15.5 $ 18,180 13.5 Sinmat On January 10, 2020, the Company acquired Sinmat, a chemical mechanical polishing slurry manufacturer. Sinmat reports into the Specialty Chemicals and Engineered Materials segment of the Company. The acquisition was accounted for under the acquisition method of accounting and Sinmat’s results of operations are included in the Company’s condensed consolidated financial statements as of and since January 10, 2020. Costs associated with the acquisition of Sinmat were $0.7 million for the six months ended June 27, 2020 and were expensed as incurred. These costs are included in the selling, general and administrative expenses in the Company’s condensed consolidated statement of operations. The acquisition does not constitute a material business combination. The purchase price for Sinmat includes cash consideration of $76.2 million, or $75.6 million net of cash acquired, which was funded from the Company’s existing cash on hand. The purchase price of Sinmat exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $31.7 million. Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets.

The 2029 Notes were issued under an indenture dated as of April 30, 2021 (the “2029 Notes Indenture”) by and among the Company, certain subsidiaries of the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”). Interest on the 2029 Notes is payable semi-annually in arrears on May 1 and November 1 of each year, commencing on November 1, 2021. The Company incurred debt issuance costs of $4.1 million in connection with the 2029 Notes. These costs are reported in the condensed consolidated balance sheet as a direct deduction from the face amount of the 2029 Notes. The Company used the net proceeds of the offering, together with cash on hand and $51 million borrowed under the Company’s senior secured revolving credit facility (the “Revolving Facility”), to pay the redemption price for the redemption in full of the $550 million aggregate principal amount of senior unsecured notes due 2026 (the “2026 Notes”) and to pay certain fees and expenses related to the offering. In connection with the redemption of the 2026 Notes, the Company incurred a loss on extinguishment of debt of $23.1 million, which is included in Other expense (income), net on the condensed consolidated statement of operations. The 2029 Notes are guaranteed, jointly and severally, fully and unconditionally, on a senior unsecured basis, by the Company’s existing and future domestic subsidiaries, other than certain excluded subsidiaries, to the extent that such subsidiaries guarantee indebtedness under the Company’s senior secured term loan facility and Revolving Facility (together, the “Senior Secured Credit Facilities”) or the Company’s 4.375% senior unsecured notes due 2028 (the “2028 Notes”), and any other subsidiary of the Company, to the extent it incurs certain additional indebtedness (collectively, the “Guarantors”). The 2029 Notes and the guarantees thereof are the Company’s and the Guarantors’ senior unsecured obligations, respectively, and will (i) rank equally in right of payment with all of the Company’s and the Guarantors’ existing and future senior indebtedness (including the 2028 Notes); (ii) rank senior to any subordinated indebtedness that the Company or the Guarantors may incur; (iii) be effectively subordinated to all of the Company’s or the Guarantors’ existing and future secured indebtedness (including the Senior Secured Credit Facilities), in each case, to the extent of the value of the assets securing such indebtedness; and (iv) be structurally subordinated in right of payment to all existing and future obligations of the Company’s subsidiaries that do not guarantee the 2029 Notes. At any time prior to May 1, 2024, the Company may, at its option, on any one or more occasions, redeem up to 40% of the aggregate principal amount of the 2029 Notes, at a redemption price equal to 103.625% of the principal amount of the 2029 Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, with an amount of cash equal to the net cash proceeds of an equity offering, as defined in the 2029 Notes Indenture, by the Company; provided that (1) at least 60% of the aggregate principal amount of 2029 Notes issued under the 2029 Notes Indenture remains outstanding immediately after the occurrence of each such redemption; and (2) the redemption occurs within 120 days of the date of the closing of such equity offering. Additionally, at any time prior to May 1, 2024, the 2029 Notes may be redeemed, in whole or in part, at the option of the Company, at a redemption price equal to 100% of the principal amount of the 2029 Notes redeemed, plus a “make whole” premium, plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date. On or after May 1, 2024, the Company may, on any one or more occasions, redeem all or a part of the 2029 Notes, at its option, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the 2029 Notes redeemed, to, but not including, the applicable date of redemption, if redeemed during the 12-month period beginning on May 1 of the years indicated below: Year Percentage 2024 102.719 % 2025 101.813 % 2026 100.906 % 2027 and thereafter 100.000 % Upon the occurrence of certain change of control events accompanied by certain ratings events, the Company will be required to offer to repurchase all of the outstanding 2029 Notes at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase. The 2029 Notes Indenture contains covenants that, among other things, limit the Company’s ability and/or the ability of the Company’s subsidiaries to: • incur liens; • engage in sales-and-leaseback transactions; and • consolidate, merge with or convey, transfer or lease all or substantially all of the Company’s and its subsidiaries’ assets to another person. The 2029 Notes Indenture also, subject to certain exceptions, limits the ability of any non-Guarantor subsidiary of the Company to incur indebtedness. These covenants are subject to a number of other limitations and exceptions as set forth in the 2029 Notes Indenture. The Company was in compliance with all of the above covenants at July 3, 2021. The 2029 Notes Indenture provides for events of default which, if certain of them occur, would permit the Trustee or the holders of at least 25% in aggregate principal amount of the then-outstanding 2029 Notes to declare the principal of, and interest or premium, if any, and any other monetary obligations on, all the then-outstanding 2029 Notes to be due and payable immediately. Amendment of Revolving Facility In connection with its issuance of the 2029 Notes, the Company amended the Revolving Facility to provide for, among other things, lending commitments in an aggregate principal amount of up to $400.0 million, up from $300.0 million, and to extend the maturity to April 30, 2026 from November 6, 2023.

	Jul. 03, 2021
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Entegris, Inc. (“Entegris”, “the Company”, “us”, “we”, or “our”) is a leading supplier of advanced materials and process solutions for the semiconductor and other high-technology industries.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, particularly receivables, inventories, property, plant and equipment, right-of-use assets, goodwill, intangibles, accrued expenses, short-term and long-term lease liability, income taxes and related accounts, and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and contain all adjustments considered necessary, and are of a normal recurring nature, to present fairly the financial position as of July 3, 2021 and December 31, 2020, and the results of operations and comprehensive income for the three and six months ended July 3, 2021 and June 27, 2020, the equity statements as of and for the three and six months ended July 3, 2021 and June 27, 2020, and cash flows for the six months ended July 3, 2021 and June 27, 2020. The condensed consolidated financial statements and accompanying notes are presented as permitted by Form 10-Q and do not contain certain information included in the Company’s annual consolidated financial statements and notes. The information included in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis and consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2020. The results of operations for the three and six months ended July 3, 2021 are not necessarily indicative of the results to be expected for the full year.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying value of cash equivalents, accounts receivable, accounts payable, accrued payroll and related benefits, and other accrued liabilities approximates fair value due to the short maturity of those items. The fair value of long-term debt, including current maturities, was $957.6 million at July 3, 2021, compared to the carrying amount of long-term debt, including current maturities, of $936.4 million at July 3, 2021.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU No. 2019-12, “Simplifying the Accounting for Income Taxes” under ASC 740, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. This guidance is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. The Company adopted this new guidance in the first quarter of fiscal 2021. The adoption of ASU 2019-12 did not have a material impact on the condensed consolidated financial statements.
