Abstract

To provide a plasma etching method capable of controlling a CD distribution in the subsequent etching of a film to be etched by controlling the distribution of etching characteristics, because a plasma can be controlled within a wide range when an antireflection film is etched. The plasma etching method plasma-etches the antireflection film formed on a body to be treated W. The plasma etching method has a process for arranging the body to be treated successively forming a film to be etched, the antireflection film and a patterned photo-resist film on a substrate in a treating vessel 10 vertically fitting a first electrode 34 and a second electrode 16 on it oppositely. The plasma etching method further has the process for introducing a treating gas into the treating vessel 10, the process for generating the plasma by applying a high-frequency power to either of the first electrode 34 and the second electrode 16, and the process for applying a DC voltage to either electrode.
