Beschreibung
Zusammenfassung:	The present invention provides a polishing pad for electrochemical mechanical polishing of conductive substrate. The pad comprises a plurality of grooves formed in a polishing surface of the polishing pad, the grooves being adapted to facilitate the flow of polishing fluid over the polishing pad. The conductive layers are respectively formed in the grooves and are in electrical communication with each other.
