Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations Entegris, Inc. (Entegris or the Company) is a leading provider of a wide range of products for purifying, protecting and transporting critical materials used in processing and manufacturing in the microelectronics 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, and intangibles, accrued expenses and 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 accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States.
	The condensed consolidated financial statements and 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, 2012. The results of operations for the nine months ended September 28, 2013 are not necessarily indicative of the results to be expected for the full year.
	Fair Value of Financial Instruments The carrying value of accounts receivable and accounts payable approximates fair value due to the short maturity of those instruments.
	Recent Accounting Pronouncements
	In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-11, Amendments to Disclosures about Offsetting Assets and Liabilities. The objective of ASU No. 2011-11 is to provide enhanced disclosures that will enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position. In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which clarifies what instruments and transactions are subject to the offsetting disclosure requirements established by ASU No. 2011-11. Derivative instruments accounted for in accordance with Accounting Standards Codification (ASC) 815, are subject to ASU No. 2011-11 disclosure requirements. These amendments are disclosure related and do not have an impact on the Company’s financial position, results of operations, comprehensive income or cash flows. ASU Nos. 2011-11 and 2013-01 are effective for reporting periods beginning after December 15, 2012. Accordingly, the Company adopted ASU Nos. 2011-11 and 2013-01 in the first quarter of fiscal 2013. The disclosures associated with ASU Nos. 2011-11 and 2013-01 are included in note 5 to the Company’s condensed consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income that amended ASU No. 2011-12 and ASU No. 2011-05. ASU No. 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either in the consolidated statements of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. These amendments are disclosure related and do not have an impact on the Company’s financial position, results of operations, comprehensive income or cash flows. ASU 2013-02 is effective for reporting periods beginning after December 15, 2012. Accordingly, the Company adopted ASU 2013-02 in the first quarter of fiscal 2013. The disclosures associated with ASU No. 2013-02 are included in the Company’s condensed consolidated statements of equity. Amounts reclassified out of accumulated other comprehensive income were not significant.
	Other ASUs issued not effective for the Company until after September 28, 2013 are not expected to have a material effect on the Company’s condensed consolidated financial statements.

Business Combinations [Abstract]
Business Combinations Policy [Policy Text Block]	ACQUISITIONS
	Jetalon
	On April 1, 2013, the Company acquired substantially all the operating assets and liabilities of Jetalon Solutions, Inc. (Jetalon), a California-based supplier of fluid metrology products. The acquired net assets became part of the Company’s Contamination Control Solutions segment. The transaction was accounted for under the acquisition method of accounting and the results of operations of the entity are included in the Company's condensed consolidated financial statements as of and since April 1, 2013. The acquisition of Jetalon’s assets and liabilities does not constitute a material business combination.
	The purchase price for Jetalon includes cash consideration of $13.4 million, funded from the Company's existing cash on hand, and earnout-based contingent consideration of up to a maximum of $14.5 million based on the operating performance of Jetalon in 2013, 2014 and 2015. Costs associated with the acquisition of Jetalon were not significant and were expensed as incurred.
	Upon acquisition, the Company recorded a contingent consideration obligation of $3.1 million representing the fair value of the earnout-based contingent consideration. This amount was estimated through a valuation model that incorporates probability-adjusted assumptions relating to the achievement of possible operating results and the likelihood of the Company making payments. This fair value measurement is based upon significant inputs not observable in the market and therefore represents a Level 3 measurement.
	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. During the third quarter of 2013, the Company assessed the contingent consideration based on the valuation methodology described above and recorded a $1.8 million gain that is reflected in the Company's condensed consolidated statements of operations.
	The purchase price of Jetalon consists of the following:
	(In thousands):	Amount
	Cash paid at closing	$	13,358
	Contingent consideration obligation	3,094
	Total purchase price	$	16,452
	The purchase price of Jetalon, including the Company's valuation of contingent consideration, exceeds the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $10.1 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. The purchase price also includes 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, which is expected to be deductible for income tax purposes.
	The following table summarizes the allocation of the purchase price to the fair values assigned to the assets and liabilities assumed at the date of acquisition:
	(In thousands):	Amount
	Accounts receivable, inventory and other assets	$	944
	Identifiable intangible assets	5,634
	Current liabilities	(216		)
	Net assets acquired	6,362
	Goodwill	10,090
	Total purchase price	$	16,452
	As of September 28, 2013, the Company has completed its fair value determinations for all elements of the Jetalon acquisition. Intangible assets, consisting mostly of technology-related intellectual property, will be amortized on a straight-line basis over an estimated useful life of approximately 10 years.
	Entegris Precision Technologies Corporation (EPT)
	On April 2, 2012, the Company acquired the remaining 50% of its EPT joint venture in Taiwan, an equity method investee in which it had previously owned a 50% equity interest. The transaction was accounted for under the acquisition method of accounting and the results of operations of the entity are included in the Company's consolidated financial statements as of and since April 2, 2012. The investee's sales and operating results were not material to the Company's condensed consolidated financial statements. The Company paid $3.4 million in cash for the additional 50% equity interest in the entity.
	The Company remeasured its previously held equity interest in the entity at its April 2, 2012 fair value of $2.9 million. Based on the carrying value of the Company's equity interest in EPT before the business combination, the Company recognized a gain of $1.3 million. In addition, in prior reporting periods the Company recognized changes in the value of its equity interest in EPT related to translation adjustments in other comprehensive income. As required under the acquisition method of accounting, the $0.2 million recognized previously in other comprehensive income was reclassified and added in the calculation of the gain noted above.
	The purchase price was allocated based on the fair values of all of the assets acquired and liabilities assumed. The sum of the purchase price of the additional 50% equity interest and the fair value of the equity interest in the investee held by the Company at the acquisition date exceeded the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $1.9 million, resulting in goodwill. EPT is part of the Company’s Contamination Control Solutions segment.
	As described above, the Company acquired businesses in 2013 and 2012. As part of the accounting for these transactions, the Company allocated the purchase price of the acquired entities based on the fair value of all the assets acquired and liabilities assumed. The valuation of the assets acquired and liabilities assumed, as well as the Company's previously held equity interest in the case of EPT, 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.
	In performing these valuations, the Company used independent appraisals, discounted cash flows and other factors as the best evidence of fair value. The key underlying assumptions of the discounted cash flows were projected revenues, gross margin expectations and operating cost estimates. There are inherent uncertainties and management judgment required in these determinations. No assurance can be given that the underlying assumptions will occur as projected. The fair value measurements of the assets acquired and liabilities assumed were based on valuations involving significant unobservable inputs, or Level 3 in the fair value hierarchy.

Nature of Operations	Nature of Operations Entegris, Inc. (Entegris or the Company) is a leading provider of a wide range of products for purifying, protecting and transporting critical materials used in processing and manufacturing in the microelectronics 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, and intangibles, accrued expenses and 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 accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States.
	The condensed consolidated financial statements and 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, 2012. The results of operations for the nine months ended September 28, 2013 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 accounts receivable and accounts payable approximates fair value due to the short maturity of those instruments.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-11, Amendments to Disclosures about Offsetting Assets and Liabilities. The objective of ASU No. 2011-11 is to provide enhanced disclosures that will enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position. In January 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which clarifies what instruments and transactions are subject to the offsetting disclosure requirements established by ASU No. 2011-11. Derivative instruments accounted for in accordance with Accounting Standards Codification (ASC) 815, are subject to ASU No. 2011-11 disclosure requirements. These amendments are disclosure related and do not have an impact on the Company’s financial position, results of operations, comprehensive income or cash flows. ASU Nos. 2011-11 and 2013-01 are effective for reporting periods beginning after December 15, 2012. Accordingly, the Company adopted ASU Nos. 2011-11 and 2013-01 in the first quarter of fiscal 2013. The disclosures associated with ASU Nos. 2011-11 and 2013-01 are included in note 5 to the Company’s condensed consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income that amended ASU No. 2011-12 and ASU No. 2011-05. ASU No. 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either in the consolidated statements of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. These amendments are disclosure related and do not have an impact on the Company’s financial position, results of operations, comprehensive income or cash flows. ASU 2013-02 is effective for reporting periods beginning after December 15, 2012. Accordingly, the Company adopted ASU 2013-02 in the first quarter of fiscal 2013. The disclosures associated with ASU No. 2013-02 are included in the Company’s condensed consolidated statements of equity. Amounts reclassified out of accumulated other comprehensive income were not significant.
	Other ASUs issued not effective for the Company until after September 28, 2013 are not expected to have a material effect on the Company’s condensed consolidated financial statements.
