Abstract:
A method of producing a silicon carbide substrate, comprising growing a silicon carbide crystal by supplying silicon atoms and carbon atoms on a surface of a silicon carbide substrate, wherein:said surface of said silicon carbide substrate on which said silicon carbide crystal is to be grown is an off-cut surface inclined 0.05.degree. to 10.degree. with respect to one of the faces selected from a (0001) face of a hexagonal silicon carbide crystal and a (111) face of a cubic silicon carbide crystal, andan amount of silicon atoms to be supplied and an amount of carbon atoms to be supplied are so controlled that the amount of silicon atoms is in excess of the amount of carbon atoms on the surface of the silicon carbide substrate.
