Abstract:
1. A film-forming apparatus for forming a thin film on a film formation subject by sputtering comprising: a vacuum chamber; a holder portion for holding the film formation subject in the vacuum chamber; multiple cathode mechanisms for respectively supporting targets made of materials different from each other so that the targets are opposed to the film formation subject in the vacuum chamber; and multiple shutters, which correspond to respective targets, movable forward and backward individually between the targets and the film formation subject to one of block and pass film-forming particles generated from the targets, wherein at least one of the multiple shutters is formed of a target material different from the materials for the plurality of the targets so that the at least one of the multiple shutters is configured as a shutter that also functions as a target, and wherein each of the targets supported by the multiple cathode mechanisms and the at least one of the multiple shutters formed of a target material are used as a target to conduct the sputtering in turn.
