Abstract:
A method of manufacturing thin-film formation apparatus having surfaces on which unnecessary thin films are deposited during sputtering, comprising the steps of:subjecting at least a portion of said surfaces to masking;subjecting said portion of said surfaces to etching processing after masking said surfaces; andremoving said masking after said etching processing in order to provide said surfaces with unevenness;wherein, after said etching processing, said portion of said surfaces which have been subjected to etching processing has a center line surface roughness (Ra) in a range of about 5 to about less than 100 .mu.m; andwherein said etching processing forms a plurality of concave and convex parts on said portion of said surfaces, and wherein one of said plurality of concave parts and said plurality of convex parts is formed regularly at constant intervals on said portion of said surfaces.
