    摘要: 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.

    摘要: A method of manufacturing a semiconductor device is disclosed that includes the treating the surface of a SiC semiconductor substrate prior to forming a gate oxide film on the SiC semiconductor substrate in order to etch the SiC semiconductor substrate by several nm to 0.1 μm with hydrogen in a reaction furnace. The treating is conducted a reduced pressure in the furnace, at a temperature of 1500° C. or higher. The manufacturing method facilitates the removal of particles and oxide residues remaining on the trench inner wall after trench etching in the manufacturing process for manufacturing a SiC semiconductor device having a fine trench-type MOS gate structure.
