Abstract:
1. A method for manufacturing a target device, comprising the steps of: disposing a backing plate in a nitrogen gas environment under a pressure lower than 1 atm; forming a protective film made of titanium nitride on a surface of the backing plate by vaporizing a titanium metal, and bringing the vaporized titanium metal to reach a surface of the backing plate and then, fixing a target plate to the backing plate; arranging an adhesion-preventing panel onto a part of the backing late where the target plate should be fixed so as to constitute an object to be film-formed by the adhesion-preventing panel and the backing plate, forming the protective film on the object to be film-formed by ionizing and vaporizing a titanium metal, and bringing the vaporized titanium metal to reach the backing plate and exposing (111) plane on the surface of the protective film made of titanium nitride: removing a part of protective film which is formed on the adhesion-preventing panel from the object to be film-formed by removing the adhesion-preventing panel from the backing plate and the exposing a surface of the backing plate where the adhesion-preventing panel was arranged; arranging an indium metal brazing material on the exposed surface of the backing plate; fixing the target plate to the backing plate by softening, melting and solidifying the metal brazing material; and then, removing the metal brazing material which is in close contact and solidified with the protective film.
