发明名称 研磨パッド及びその製造方法
摘要 Provided are a polishing pad which remedies the problem of scratches occurring when a conventional hard (dry) polishing pad is used, which is excellent in polishing rate and polishing uniformity, and which can be used for not only primary polishing but also finish polishing, and a manufacturing method therefor. The polishing pad is a polishing pad for polishing a semiconductor device, comprising a polishing layer having a polyurethane-polyurea resin foam containing substantially spherical cells, wherein the polyurethane-polyurea resin foam has a hard segment content (HSC) in a range from 26 to 34%, and has a density D in a range from 0.30 to 0.60 g/cm 3 , the hard segment content (HSC) being determined by the following formula (1) :
