    Abstract: PURPOSE: A plasma etching treatment apparatus and method, and a method for manufacturing a semiconductor device are provided to control a protective film to be superfluously thickened by controlling the thickness of the protective film which is formed in the off of bias under 10Å. CONSTITUTION: A gas supply part(13) supplies gas for plasma processing within a treatment basin(12). A microwave generator(15) generates plasma excited microwaves. A waveguide(16) and a coaxial waveguide(17) transmit the microwaves generated by the microwave generator within the treatment basin. A dielectric plate(18) spreads the microwave to a diametric direction. A slot antenna plate(20) radiates the microwave. A pressure control means controls the pressure within the treatment basin. A bias power supply means supplies AC bias power to a supporting stand.
