Abstract
Provided are a film-forming apparatus and a film-forming method capable of preventing complication of an apparatus mechanism in formation of a thin film of multiple materials by sputtering to simplify the apparatus mechanism and preventing an increase in an apparatus cost. The film-forming apparatus includes a vacuum chamber, a substrate holder for holding a substrate, cathode mechanisms for supporting targets respectively so that the targets can be opposed to the substrate in the vacuum chamber, and shutters movable forward and backward individually between the targets made of different materials and the substrate to block or pass film-forming particles generated from the targets. At least one of the shutters is formed of a target material different from those for the targets so that the at least one of the shutters is configured as a shutter that also functions as a target.
