发明名称 POLISHING PAD
摘要 An object of the present invention is to provide a polishing pad which enables high accuracy optical end-point detection in a state where polishing is carrying out, and which can prevent slurry leakage from a polishing layer to a cushion layer even in the case of being used for a long period. Another object is to provide a method for producing a semiconductor device using the polishing pad. The present invention relates to a polishing pad in which a polishing layer having a polishing region and a light-transmitting region, and a cushion layer having a through hole are laminated via a double-sided adhesive sheet such that the light-transmitting region and the through hole are laid one upon another, wherein a transparent member is stuck on an adhesive layer of the double-sided adhesive sheet in the through hole.
