Abstract:
1. A film deposition apparatus comprising: a process chamber inside which a reduced pressure space is maintained; a substrate holding portion that is made of a material including carbon as a primary constituent and holds a substrate wherein the substrate holding portion includes a susceptor by which a plurality of substrates can be supported and a structure-to-be-heated that is placed so as to surround the susceptor; a coil that is arranged outside the process chamber and inductively heats the substrate holding portion; a thermal insulation member holding structure that allows a thermal insulation member that covers the substrate holding portion to be away from the process chamber, wherein the thermal insulation member holding structure separates the reduced pressure space into a film deposition gas supplied space and a thermal insulation space, wherein the film deposition gas supplied space is provided with the substrate holding portion and the thermal insulation member, and wherein the thermal insulation space is defined between the process chamber and the thermal insulation member; a gas supplying portion that supplies a film deposition gas to the film deposition gas supplied space; and a gas line that supplies a cooling gas for cooling the process chamber to the thermal insulation space, wherein the cooling gas is provided to the thermal insulation space and is unmixed with the film deposition gas, which is provided to the film deposition gas supplied space.
