Abstract:
A method of manufacturing a semiconductor device by using a polishing cloth, comprising:providing a substrate; forming an insulating film on said substrate, followed by forming a wiring groove on said substrate through said insulating film; forming a metal wiring layer on the substrate and in said wiring groove; and polishing mechanically the metal wiring layer formed on the substrate and in said wiring groove with a polishing cloth so as to remove an undesired portion of the metal wiring layer and, thus, to flatten the surface of the metal wiring layer, said polishing cloth comprising a base body holding a slurry on the surface and serving to mechanically polish a surface of a target object to be polished, and fine particles dispersed in said base body and soluble in a solvent, wherein a coating layer insoluble by a solvent in the slurry is formed to cover the outer surfaces of the fine particles.
