Patent ID: 8440270

Claim:
A film deposition apparatus comprising: a processing chamber having a vacuum space thereinside and to which a film deposition gas is supplied; a substrate supporting unit which is disposed in the vacuum space and serves to support a substrate; a coil unit which serves to inductively heat the substrate supporting unit and is divided into a plurality of coils; and a coil control unit which independently controls the coils, wherein the coil control unit includes a power control unit configured to separately apply a high frequency power to each of the coils; wherein the coils are arranged in accordance with a flow of the film deposition gas in the processing chamber; wherein the substrate supporting unit includes a mounting table for mounting thereon the substrate and a heating structure disposed around the mounting table to surround the mounting table, wherein the mounting table and the heating structure are inductively heated by the coil unit and the substrate is heated by radiant heat from the mounting table and the heating structure, wherein the heating structure has two openings disposed opposite to each other, so that the film deposition gas is supplied from one of the openings and exhausted through the other opening, wherein a heat insulating member supporting structure is provided in the processing chamber and divides the vacuum space into a film deposition gas supply space and a heat insulating space, wherein the film deposition gas is supplied into the film deposition gas supply space, and wherein a heat insulating member is provided in the heat insulating member supporting structure to be separated from a processing chamber wall and to surround the substrate supporting unit.
