摘要:
A method for fabricating a semiconductor device includes forming a barrier metal film on a substrate with an opening defined therein, forming a copper-containing film on said barrier metal film after having formed said barrier metal film on a surface of said substrate and an inner wall of said opening, and polishing said copper-containing film and said barrier metal film while applying a voltage to said substrate in a state that said copper-containing film and said barrier metal film are exposed.
