Abstract:
An electroplating apparatus comprising:a holder configured to hold a substrate to be processed, said substrate serving as a cathode and being connected to a cathode contact; a dummy cathode placed in a position different from said holder; an anode capable of facing, substantially face to face, both a surface to be plated of said substrate held by said holder and said dummy cathode; alternately; a moving mechanism configured to move said anode between a position facing said substrate holder and a position facing said dummy cathode; and a power supply connected between said cathode contact and said anode, and between said dummy cathode and said anode to supply an electric current between said anode and said dummy substrate, and between said anode and said dummy cathode via an electrolytic agent filled between said substrate and said anode, and between said dummy cathode and said anode.
