Abstract

A film deposition apparatus reduces hillock formation while yielding uniform film thickness distribution. A film deposition apparatus of a present embodiment includes: a chamber; a rotary table that circulates and carries a workpiece W along a circumferential transfer path L; multiple targets that contain a film deposition material, and that are provided in positions at different radial distances from a center of rotation of the rotary table; a shield member that forms a film deposition chamber surrounding a region where the film deposition material scatters, and that has an opening on the side facing the circulated and carried workpiece; and a plasma generator that includes a sputter gas introduction unit for introducing a sputter gas into the film deposition chamber, and a power supply unit for applying power to the target, and that generates plasma in the sputter gas Gin the film deposition chamber.
