Zusammenfassung:The present disclosure relates to a polishing pad, a method of manufacturing the polishing pad, and a method of manufacturing a semiconductor device using the same. In the polishing pad, an unexpanded solid-phase blowing agent is included in a polishing composition when a polishing layer is manufactured, and the unexpanded solid-phase blowing agent is expanded during a curing process to form a plurality of uniform pores in the polishing layer, such that defects occurring on a surface of the semiconductor substrate may be prevented. In addition, the present disclosure may provide a method of manufacturing a semiconductor device to which the polishing pad is applied.
