Abstract:
According to one embodiment, a film formation apparatus includes a chamber having an interior to be vacuumed, a carrying unit which is provided in the chamber, and which carries a workpiece that has a processing target surface in a solid shape along a circular carrying path, a film formation unit that causes a film formation material to be deposited by sputtering on the workpiece that is being carried by the carrying unit to form a film thereon, and a shielding member which has an opening located at a side where the workpiece passes through, and which forms a film formation chamber where the film formation by the film formation unit is performed. A compensation plate that protrudes in the film formation chamber is provided, and the compensation plate has a solid shape along a shape of the processing target surface of the workpiece, and is provided at a position facing the workpiece.
