Abstract
A technique to prevent peeling of deposits formed on the surface of the inner walls of the thin-film formation apparatus and the members inside the apparatus and to suppress particle production without contamination of the inside of the apparatus. A member for a thin-film formation apparatus having inner walls and a method for manufacturing the member is provided. A plurality of unevenness is provided on at least a portion of the surface of the member and the inner walls on which unnecessary thin films are deposited. The surfaces are subjected to masking, and then, etching processing to form the plurality of unevenness. After the etching processing the masking is removed.
