摘要： A composite electrolytic processing method makes it possible to remove a conductive film without leaving it in an electrically-insulated state on an underlying barrier film, thereby exposing the barrier film. The electrochemical mechanical polishing method includes: applying a voltage between a first electrode connected to one pole of a power source and a second electrode, connected to the other pole of the power source, for feeding electricity to a conductive film of a polishing object; filling an electrolytic liquid into a space between the first electrode and the conductive film of the polishing object; and pressing and rubbing the conductive film against a polishing surface of a polishing pad to polish the conductive film in such a manner that a barrier film underlying the conductive film becomes gradually exposed from the center toward the periphery of the polishing object.
