Patent ID: 8372196

Claim:
A susceptor device for use to hold a material wafer in a manufacturing apparatus of an epitaxial wafer, the manufacturing apparatus irradiating radiation light toward the material wafer from a back surface side opposite to a film-forming surface of the material wafer to heat the material wafer, the manufacturing apparatus manufacturing the epitaxial wafer by growing an epitaxial film in vapor phase on the film-forming surface while the material wafer is heated, the susceptor device comprising: a susceptor having a mounting surface on which the material wafer is mounted; a periphery support that supports a periphery adjacent portion of the susceptor; and a temperature controller that controls a temperature of a portion of the susceptor, the portion of the susceptor corresponding to a center of the material wafer mounted on the susceptor, the temperature controller having a substantially rod shape and extending in a direction substantially orthogonal to a non-mounting surface on a side of the non-mounting surface opposite to the mounting surface, an end of the temperature controller being adjacent to a portion of the non-mounting surface without contacting, the portion of the non-mounting surface corresponding to the center of the material wafer.
