ABSTRACT:
A substrate processing apparatus can carry out removal of a passive layer (ruthenium oxide) present on a surface of a ruthenium film and electroplating successively, and can reduce the terminal effect at the time of the removal of the passive layer (ruthenium oxide) from the ruthenium film. The substrate processing apparatus includes: an electrolytic processing apparatus for electrochemically removing a passive layer, formed on a surface of a ruthenium film on a substrate, by electrolytic processing with the ruthenium film as a cathode; a copper electroplating apparatus for carrying out copper electroplating on the surface of the ruthenium film on the substrate; and an apparatus frame housing the electrolytic processing apparatus and the copper electroplating apparatus.
