Abstract
An object of the present invention is to provide an epitaxial growth apparatus and an epitaxial growth method that can suppress variation in in-face temperature of a semiconductor wafer caused by deflection of a susceptor and manufacture an epitaxial wafers of high quality. Specifically, the present invention provides an epitaxial growth apparatus for forming an epitaxial film on a semiconductor wafer placed in a chamber having a supply port and an exhaust port for a treatment gas, the apparatus comprising: a susceptor for placing the semiconductor wafer thereon within the chamber; and a susceptor support shaft for supporting the susceptor at an underneath portion of the susceptor, wherein the susceptor support shaft has a support column located substantially coaxial with the center of the susceptor, and at least four support arms extending radially from the top end of the support column with equal intervals therebetween.
