A plasma processing apparatus includes a processing chamber; a plasma generating unit for generating a plasma of a gas supplied into the processing chamber; a substrate mounting table, disposed in the processing chamber, for mounting a semiconductor substrate having a surface on which an etching and/or a film forming process is to be performed. The apparatus further includes a metal member disposed in the processing chamber and to be etched by the plasma generated in the processing chamber to release a precursor of a film to be formed by the film forming process into the processing chamber; a gas supply unit for supplying a first and a second gas into the processing chamber, wherein the second gas which includes halogen atoms and is different from the first gas; a first and a second wiring for supplying high frequency power to the metal member and the substrate mounting table, respectively.
