Abstract:
1. A substrate processing apparatus comprising: a common substrate processing section having a substrate stage for rotatably and vertically-movably holding a substrate with a front surface of the substrate facing upwardly and alternatively forming an electrolytic solution chamber for holding an electrolytic solution and a plating solution chamber for holding a plating solution on the substrate held by the substrate stage; an electrolytic processing apparatus for electrochemically removing a passive layer formed on a surface of a ruthenium film on the substrate by electrolytic processing in which the ruthenium film is a cathode, said electrolytic processing apparatus comprising said common substrate processing section and an electrolytic processing anode head; a copper electroplating apparatus for carrying out copper electroplating on the surface of the ruthenium film on the substrate, said copper processing apparatus comprising said common substrate processing section and a plating anode head; and an apparatus frame housing said electrolytic processing apparatus and said copper electroplating apparatus.
