  • Publication number: 20230219191
    Abstract: The present disclosure provides a polishing pad and a method of manufacturing a semiconductor device using the same. The method includes disposing a target layer on a semiconductor substrate and performing a chemical mechanical polishing process on the target layer using a polishing pad including a plurality of polishing protrusions facing the target layer. Each of the polishing protrusions includes a protruding portion and a surface layer at least partially covering the protruding portion, wherein the protruding portion is more elastic than the surface layer, and wherein the surface layer is harder than the protruding portion.
