Abstract
An epitaxial film deposition system includes a reactor, a susceptor, a wafer heating unit, a reactant gas supply orifice, and an aperture for venting the reactant gas. The reactant gas is supplied to a reactor region between the susceptor and a graphite plate so as to circulate in layered flow in a direction along the reactor inner wall in the planar direction of a mounted SiC wafer. The temperature of the wafer is controlled by a high frequency coil and halogen lamps based on temperatures detected by a pyrometer. By circulating the reactant gas over the surface of the stationary wafer, it is possible to form, under various process conditions, an SiC epitaxial film having good film quality and good uniformity of film thickness, without providing any wafer rotation mechanism.
