发明名称 Accurately monitored CMP recycling
摘要 A method is provided for reformulating a chemical mechanical planarization (CMP) slurry for use in conjunction with a CMP tool having an active cycle during which the tool is being used to planarize a substrate, and a rinse cycle during which the tool is being rinsed. The method comprises (a) receiving a feed stream from the CMP tool, at least a portion of the feed stream comprising abrasive particles disposed in a liquid medium; (b) during at least a portion of the rinse cycle, sending the feedstream received from the CMP tool to a first location; and (c) during at least a portion of the active cycle, sending the feedstream received from the CMP tool to a second location where the feedstream undergoes processing to reformulate the slurry.
