ABSTRACT:
A plasma processor electrode includes a support member disposed to face to an electrode that holds a substrate to be treated, an electrode plate fixed to the support member and equipped with gas injection holes and a screw hole open and facing to the support member to supply a processing gas through the gas discharge hole into a processing space formed between the electrode plate and the electrode to generate a plasma in the processing space, and a fastening unit that clamps the electrode plate on the support member by fastening the electrode plate to the support member with a screw driven into the screw hole from the support member.
