Noncontrolling Interest [Abstract]
Stockholders' Equity and Noncontrolling Interests	11. STOCKHOLDERS’ EQUITY AND NONCONTROLLING INTERESTS Noncontrolling Interests QGT, through its wholly-owned subsidiary in Singapore, owns 51.0% of the outstanding shares of Cinos Korea, a South Korean company that provides outsourced cleaning and recycling of precision parts for the semiconductor industry through its operating facilities in South Korea and through a 60.0% interest in Cinos China. QGT is obligated to purchase shares held by another shareholder of Cinos Korea representing a 35.0% interest in Cinos Korea. QGT accounted for this unconditional obligation as an assumed liability and derecognized any noncontrolling interest related to the 35.0%, which brings its controlling interest up to 86.0%. The carrying value of the remaining 14.0% interest held by another shareholder in Cinos Korea and the 40.0% interest in Cinos China are presented as noncontrolling interests in the accompanying Condensed Consolidated Financial Statements. The fair values of the noncontrolling interests were estimated based on the values of Cinos Korea and Cinos China on a 100.0% basis. The values were calculated based on the pro-rata portion of total QGT earnings before interest expense, taxes, depreciation and amortization contributed by each entity. The Company is obligated to purchase shares owned by a Cinos Korea shareholder. A certain number of shares would be purchased at a fixed price per share, while the other remaining shares would be purchased based on the greater of the then fair value of the stock and the fixed price per share (floor). The Company has a firm obligation to purchase the shares and a call option, while the other shareholder has a put option. As of March 26, 2021, the fair value of the obligation is $12.6 million which has been recorded as a non-current liability in the accompanying consolidated balance sheets and represents a Level 3 measurement as discussed in Note 4 of the Company’s Notes to Condensed Consolidated Financial Statements. The agreement with Cinos Korea allows for the common stock purchase obligation to become due in December 2022, and once completed, the Company will own 86.0% of Cinos Korea.
