WebMar 12, 2015 · Abstract. Mixed abrasive slurry (MAS) is one of the non-traditional slurries with more than two different sizes, shapes or materials of abrasives which are to improve a chemical mechanical polishing (CMP) performance such as a removal rate. This paper focuses on the MAS mixed with two different sized abrasives and controlled by mixing ratio. WebCMP slurries are used in conjunction with CMP pads or polishing naps, which are rotated and held against a substrate or wafer surface during the planarization process. Products …
