发明名称 Process for producing silicon carbide single crystal and production apparatus therefor
摘要 A process for producing a silicon carbide single crystal and a production apparatus therefor which enable, under stable conditions, continuous production of a silicon carbide single crystal which has a reduced density and dispersion of crystal defects in a growth direction, no lattice distortion, a large diameter, and constant quality. A melted or vaporized silicon material is introduced from the outside of a reaction system into a carbon material heated to a temperature equal to or higher than a temperature at which the silicon material vaporizes; and a reaction gas containing silicon gas and silicon carbide gas generated by a reaction between the carbon material and the silicon material is caused to reach a silicon carbide seed crystal substrate 5 which is held at a temperature lower than that of the carbon material, so that a silicon carbide single crystal grows on the silicon carbide seed crystal substrate.
