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 global developer, manufacturer and supplier of microcontamination control products, specialty chemicals and advanced materials handling solutions for manufacturing processes in 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 June 29, 2019 and December 31, 2018 , and the results of operations and comprehensive income for the three and six months ended June 29, 2019 and June 30, 2018 , the equity statements as of and for the three and six-months periods ended June 29, 2019 and June 30, 2018 , and cash flows for the six months ended June 29, 2019 and June 30, 2018 . 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, 2018 . The results of operations for the three and six months ended June 29, 2019 are not necessarily indicative of the results to be expected for the full year. Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets include operating leases. Lease liabilities for operating leases are classified in “Other accrued liabilities” and “Long-term lease liabilities” in our condensed consolidated balance sheet. We do not have material financing leases. Operating assets and liabilities are recognized at commencement date based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The ROU assets includes prepaid lease payments 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 that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Lease and non-lease components are generally accounted for separately for real estate leases. For non-real estate leases, we account for the lease and non-lease components as a single lease component. 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 $946.4 million at June 29, 2019 , compared to the carrying amount of long-term debt, including current maturities, of $937.7 million at June 29, 2019 . Recent Accounting Pronouncements Adopted in 2019 In February 2016, the FASB established Topic 842, Leases , by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and expense recognition in the income statement. The Company adopted ASU No. 2016-02 using the modified retrospective method. See Note 9 Leases to the condensed consolidated financial statements for further details.

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 goods sold. 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 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 over time at which the Company has satisfied the performance obligation. The Company also enters into arrangements to license its intellectual property. These arrangements typically permit the customer to use a specialized manufacturing process and in return the Company receives a royalty fee. If applicable, the Company recognizes revenue 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 deferred in the balance sheet and is recognized as revenue when the free product is redeemed or when the likelihood of redemption is remote. The Company deems the amount immaterial for disclosure. The Company provides for the estimated costs of fulfilling our 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 we do 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 adjust the amounts as necessary. The Company’s contracts are generally short-term in nature. Most contracts do not exceed twelve months. Payment terms vary by the type and location of the Company’s customers and the products or services offered. The term between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. Those customers that prepay are represented by the contract liabilities below until the performance obligations are satisfied.

Business Combinations [Abstract]
Business Combination Disclosure	ACQUISITIONS Digital Specialty Chemicals On March 8, 2019 , the Company acquired Digital Specialty Chemicals Limited (DSC), a Toronto, Canada-based provider of advanced materials to the specialty chemical, technology, and pharmaceutical industries. DSC reports into the Specialty Chemicals and Engineered Materials division of the Company. The acquisition was accounted for under the acquisition method of accounting and the results of operations of DSC are included in the Company’s condensed consolidated financial statements as of and since March 8, 2019 . Costs associated with the acquisition of DSC were $2.1 million for the six months ended June 29, 2019 and were expensed as incurred. These costs are included in selling, general and administrative expense in the Company’s condensed consolidated statements of operations. The acquisition does not constitute a material business combination. The purchase price for DSC is $64.0 million , net of cash acquired. The purchase price includes (1) cash consideration of $49.7 million , or $49.3 million net of cash acquired, subject to revision for customary working capital adjustments, which was funded from the Company’s existing cash on hand, (2) a fixed deferred payment of $16.1 million that is due on March 31, 2022, recorded at $14.0 million representing the fair value of this fixed deferred payment as of the acquisition date, and (3) an earnout-based contingent consideration of $0.7 million based on the operating performance of DSC for a twelve-month period ended March 31, 2021. The fair value of the fixed deferred payment was determined by taking the present value of this fixed deferred payment based on the term and discount factor. The fixed deferred payment is reflected in the pension benefit obligations and other liabilities in the Company’s condensed consolidated balance sheets. Upon closing the acquisition, the Company recorded a contingent consideration obligation of $0.7 million representing the fair value of the earnout-based contingent consideration. This amount was estimated based on a Black Scholes model. Subsequent changes in the fair value of this obligation will be recognized as adjustments to the contingent consideration obligation and reflected within the Company’s condensed consolidated statements of operations. The purchase price of DSC exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $34.5 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 deductible for income tax purposes. The following table summarizes the provisional allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of the acquisition and as adjusted as of June 29, 2019: (In thousands): As of March 8, 2019 As of June 29, 2019 Trade accounts and note receivable, net $ 1,840 $ 1,840 Inventories, net 5,523 4,353 Other current assets 1,389 1,391 Property, plant and equipment 16,791 16,652 Identifiable intangible assets 7,976 6,886 Right-of-use assets 79 79 Deferred tax asset 1,104 1,104 Other noncurrent assets — 28 Accounts payable and accrued liabilities (2,461 ) (2,540 ) Deferred tax liabilities (2,861 ) (318 ) Long-term lease liability (37 ) (37 ) Net assets acquired 29,343 29,438 Goodwill 35,133 34,516 Total purchase price, net of cash acquired $ 64,476 $ 63,954 The final valuation of assets acquired and liabilities assumed is expected to be completed as soon as possible, but not later than one year from the acquisition date. Given the size and complexity of the acquisition, the valuation of certain assets and liabilities is still being completed and is subject to final review. To the extent that the Company’s estimates require adjustment, the Company will modify the values. SAES Pure Gas On June 25, 2018 , the Company acquired the SAES Pure Gas business (SPG) from SAES Getters S.p.A. for approximately $352.7 million in cash, or $341.5 million net of cash acquired, funded from the Company’s existing cash on hand. The acquisition was accounted for under the acquisition method of accounting and the results of operations of SPG are included in the Company’s condensed consolidated financial statements as of and since June 25, 2018 . Direct costs of $4.8 million associated with the acquisition of SPG, consisting mainly of professional and consulting fees, were expensed as incurred for the year ended December 31, 2018. These costs are included in selling, general and administrative expense in the Company’s condensed consolidated statements of operations. SPG, based in San Luis Obispo, California, is a leading provider of high-capacity gas purification systems used in semiconductor manufacturing and adjacent markets, and reports into the Microcontamination Control Division of the Company. This acquisition expands the gas purification solutions portfolio in our Microcontamination Control Division with high-capacity products suited for bulk chemical purification applications. The following table summarizes the final allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at December 31, 2018 and as adjusted as of June 29, 2019: (In thousands): As of December 31, 2018 As of June 29, 2019 Trade accounts and note receivable, net $ 19,173 $ 19,173 Inventories, net 42,758 42,758 Other current assets 1,322 706 Property, plant and equipment 6,653 6,653 Identifiable intangible assets 150,430 150,430 Deferred tax assets 831 734 Other noncurrent assets 12 12 Current liabilities (26,473 ) (26,473 ) Deferred tax liabilities (35,533 ) (35,271 ) Other noncurrent liabilities (1,412 ) (1,412 ) Net assets acquired 157,761 157,310 Goodwill 183,729 184,180 Total purchase price, net of cash acquired $ 341,490 $ 341,490 The fair value of acquired inventories of $42.8 million is valued at the estimated selling price less cost of disposal and reasonable profit for the selling effort. The fair value write-up of acquired work-in-process and finished goods inventory was $8.9 million , the amount of which was amortized over the expected turn of the acquired inventory. Accordingly, $0.0 million and $2.0 million incremental cost of sales charge associated with the fair value write-up of inventory acquired in the acquisition of SPG was recorded for the three and six months ended June 29, 2019, respectively. The fair value of acquired property, plant and equipment of $6.7 million is valued at its value-in-use. The Company recognized the following finite-lived intangible assets as part of the acquisition of SPG: (In thousands) Amount Weighted average life in years Developed technology $ 20,070 8.0 Trademarks and trade names 6,670 12.0 Customer relationships 107,790 12.0 Other 15,900 0.9 $ 150,430 10.0 The acquired identifiable intangible assets are being amortized on a straight-line basis. The fair value of acquired identifiable intangible assets was determined using the “income approach”. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by the Company’s management. There are inherent uncertainties and management judgment required in these determinations. The fair value measurements of the assets acquired and liabilities assumed were based on valuations involving significant unobservable inputs, or Level 3 inputs in the fair value hierarchy. The purchase price of SPG exceeded the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $184.2 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 purchase price also included the fair values of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value in addition to a going-concern element that represents the Company’s ability to earn a higher rate of return on the group of assets than would be expected on the separate assets as determined during the valuation process. This additional investment value resulted in goodwill. No amount of goodwill is expected to be deductible for income tax purposes. During the quarter ended June 29, 2019, the Company finalized its fair value determination of the assets acquired and liabilities assumed. The valuation of the assets acquired and liabilities assumed was based on the information that was available as of the acquisitions date, and the expectations and assumptions that have been deemed reasonable by the Company’s management. Particle Sizing Systems On January 22, 2018 , the Company acquired Particle Sizing Systems, LLC (PSS), which provides particle sizing instrumentation for liquid applications to the semiconductor and life science industries. The acquired assets and assumed liabilities became part of the Company’s Advanced Materials Handling (AMH) segment. The transaction was accounted for under the acquisition method of accounting and the results of operations of PSS are included in the Company’s condensed consolidated financial statements since January 22, 2018 . The acquisition does not constitute a material business combination. The purchase price for PSS was cash consideration of $37.3 million , funded from the Company’s existing cash on hand. Costs associated with the acquisition of the product line were not significant and were expensed as incurred. The purchase price of PSS exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $8.8 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 deductible for income tax purposes. During the year ended December 31, 2018, the Company finalized its fair value determinations of the assets acquired and liabilities assumed. The valuation of the assets acquired and liabilities assumed was based on the information that was available as of the acquisition date, and the expectations and assumptions that have been deemed reasonable by the Company’s management. Flex Concepts On June 26, 2018 , the Company acquired Flex Concepts, Inc. (Flex), a technology company focused on single-use fluid handling bags, tubing manifolds and hardware for the life sciences industry. The purchase price of Flex was for cash consideration of $1.9 million . The transaction was accounted for under the acquisition method of accounting and the results of operations of Flex are included in the Company’s condensed consolidated financial statements since June 26, 2018 . The acquisition does not constitute a material business combination.

Leases [Abstract]
Leases of Lessee Disclosure	LEASES Adoption of ASC ASU No. 2016-02, Leases On January 1, 2019, the Company adopted ASU No. 2016-02 using the modified retrospective method applied to existing leases in place as of January 1, 2019. Leases entered into after January 1, 2019 are presented under the provisions of ASU No. 2016-02, while prior periods are not adjusted and continue to be reported in accordance with previous accounting guidance. Leases commencing or renewing after the adoption date are evaluated based on the guidance in ASU No. 2016-02 and may result in more finance leases being recognized even for the renewal of previously classified operating leases. The Company elected to adopt the ‘package of practical expedients’, which permitted the Company not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the practical expedient pertaining to land easements, which allowed the Company to exclude evaluation of all existing land easements in connection with the adoption of the new lease requirements to assess whether they meet the definition of a lease. The Company did not elect the use-of-hindsight practical expedient and therefore did not reassess the lease terms for purposes of calculation of the lease liabilities and right-of-use assets at the adoption date. The Company elected the short-term lease recognition exemption for all leases that qualified. This means, for those leases that qualified, the Company did not recognize right-of-use assets or lease liabilities, and this included not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for all leases other than leases of real estate, and this included not separating lease and non-lease components for all leases other than leases of real estate in transition. The Company adopted ASU 2016-02 using the modified retrospective method, recognizing the cumulative effect of application as an adjustment to the opening balance sheet. The standard had a material impact on our condensed consolidated balance sheets, but did not have a material impact on our condensed consolidated statement of income or cash flows. The most significant impact was the recognition of the right-of-use asset and lease liabilities for operating leases. As of June 29, 2019, we do not have any material finance leases. The details of the impact of the changes made to the Company’s condensed consolidated balance sheet date as of January 1, 2019, the date of adoption, are reflected in the following table.

Our leases have remaining lease terms of 1 year to 13 years, some of which may include options to extend the lease for up to 6 years, and some of which may include options to terminate the leases within 1 year . As of June 29, 2019 , the Company has obtained $3.0 million of operating lease assets in exchange for lease obligations. As of June 29, 2019, the Company’s operating lease components with initial or remaining terms in excess of one year were classified on the condensed consolidated balance sheet as follows: ( In thousands ) Classification June 29, 2019 Assets Right-of-use assets Right-of-use assets $ 44,176 Liabilities Short-term lease liability Other accrued liabilities 8,820 Long-term lease liability Long-term lease liability 40,612 Total lease liabilities $ 49,432 Expense for leases less than 12 months for the three and six months ended June 29, 2019 were not material.

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING The Company’s financial segment reporting reflects an organizational alignment intended to leverage the Company’s unique portfolio of capabilities to create value for its customers by developing mission-critical solutions to maximize manufacturing yields and enable higher performance of devices. While these segments have separate products and technical know-how, they share common business systems and processes, technology centers, and strategic and technology roadmaps. The Company leverages its expertise from these three segments to create new and increasingly integrated solutions for its customers. The Company’s business is reported in the following segments: • Specialty Chemicals and Engineered Materials (SCEM): SCEM provides high-performance and high-purity process chemistries, gases, and materials and safe and efficient delivery systems to support semiconductor and other advanced manufacturing processes. • Microcontamination Control (MC): MC solutions purify critical liquid chemistries and gases used in semiconductor manufacturing processes and other high-technology industries. • Advanced Materials Handling (AMH): AMH develops solutions to monitor, protect, transport, and deliver critical liquid chemistries, wafers, and substrates for a broad set of applications in the semiconductor industry and other high-technology industries. In the first quarter of 2019, the Company changed its definition of segment profit to include inter-segment sales. The Company updated its recognition of inter-segment sales to recognize the revenue and profit associated with products and components produced in one segment and supplied to another, before being sold to the ultimate end customer. The Company accounts for inter-segment sales and transfers as if the sales or transfers were to third parties, that is, at approximate market prices. Inter-segment sales are presented as an elimination below. Segment profit is defined as net sales less direct and indirect segment operating expenses, including certain general and administrative costs for the Company’s human resources, finance and information technology functions. The remaining unallocated expenses consist mainly of the Company’s corporate functions as well as interest expense, amortization of intangible assets and income tax expense. Prior quarter information was recast to reflect the change in the Company’s definition of segment profit.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Entegris, Inc. (“Entegris”, “the Company”, “us”, “we”, or “our”) is a leading global developer, manufacturer and supplier of microcontamination control products, specialty chemicals and advanced materials handling solutions for manufacturing processes in 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 June 29, 2019 and December 31, 2018 , and the results of operations and comprehensive income for the three and six months ended June 29, 2019 and June 30, 2018 , the equity statements as of and for the three and six-months periods ended June 29, 2019 and June 30, 2018 , and cash flows for the six months ended June 29, 2019 and June 30, 2018 . 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, 2018 . The results of operations for the three and six months ended June 29, 2019 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 $946.4 million at June 29, 2019 , compared to the carrying amount of long-term debt, including current maturities, of $937.7 million at June 29, 2019 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2019 In February 2016, the FASB established Topic 842, Leases , by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements. The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and expense recognition in the income statement. The Company adopted ASU No. 2016-02 using the modified retrospective method. See Note 9 Leases to the condensed consolidated financial statements for further details.
