Patent ID: 8043471

Claim:
A plasma processing apparatus comprising: a processing chamber including a cylindrical bell jar provided at an upper end part of the processing chamber; a plasma generating unit including a coil wound around an outer periphery of the bell jar and a grounded conductive member disposed on an outer side of an upper wall of the bell jar which generates a plasma of a gas supplied into the processing chamber; a substrate mounting table, disposed in the processing chamber, which mounts a semiconductor substrate having a surface on which a film is to be formed; a metal member disposed in the processing chamber to be etched by the plasma generated in the processing chamber to release a precursor of the film into the processing chamber; a holder in the bell jar which detachably holds the metal member; a gas supply unit which supplies a gas including halogen atoms into the processing chamber; a first wiring which supplies a first high frequency power to the metal member to attract the plasma generated in the processing chamber to the metal member; a second wiring which supplies a second high frequency power to the substrate mounting table to form an electric field between the substrate mounting table and the conductive member and to attract the plasma generated in the processing chamber to the semiconductor substrate; and a third wiring which supplies a third high frequency power to the coil to form an induced electromagnetic field within the bell jar, wherein the metal member and the holder are disposed in a plasma generating space in which the plasma is generated by the plasma generating unit, the plasma generating space is provided between an inner side of the upper wall of the bell jar and the substrate mounting table, wherein the metal member and the holder are surrounded by the coil, and wherein the metal member and the holder are disposed to be spaced apart from the substrate mounting table and from the upper wall of the bell jar.
