Abstract PROBLEM TO BE SOLVED: To obtain a current density and electric field which the conventional polishing pad has been short of. SOLUTION: In order to provide a polishing pad 4 for electrochemical mechanical polishing of a conductive substrate, the pad includes a plurality of grooves 24 which are formed on the polishing surface of the polishing pad and adapted to facilitate the fluidity of polishing fluid on the polishing pad. Conductive layers 26 are respectively formed in grooves and electrically coupled to each other. COPYRIGHT: (C)2005,JPO&NCIPI
