    摘要: In a plasma etching apparatus for performing a plasma etching on a surface of a substrate mounted on a susceptor in a processing vessel, a focus ring is installed to surround the substrate and has a first region at an inner side on a surface thereof, in which an average surface roughness is small such that a reaction product produced during an etching processing is not captured to be deposited, and a second region at an outer side from the first region, in which an average surface roughness is large such that a reaction product produced during the etching process is captured to be deposited. A boundary between the first and the second region is a part where an etching amount is relatively significantly changed compared to other parts while the focus ring is equipped in the plasma etching apparatus and the plasma etching is performed on the substrate.
