In the single crystal SiC according to the invention, heat treatment is performed in an inert gas atmosphere under a state where a cutting plane of a single crystal α-SiC substrate which is produced in a plate-like form by cutting along (1 1 {overscore (2)} 0) Miller index plane ±10°, and (2 2 0) Miller index plane of a polycrystalline β-SiC plate are superimposed on each other, whereby single crystal having a crystal orientation of an orientation of the cutting plane is integrally grown in the polycrystalline β-SiC plate in conformity with the single crystal α-SiC substrate. According to this configuration, single crystal SiC of very high quality is obtained to which influence of micropipes of the single crystal α-SiC substrate is not transferred, thereby preventing distortion and micropipe defects from occurring.
Single crystal SiC wherein
A method of growing single crystal SiC in which heat treatment is performed while superimposing a single crystal α-SiC substrate and a polycrystalline β-SiC plate, wherein under a state where (2 2 0) Miller index plane of said β-SiC plate is superimposed on a cutting plane of said single crystal α-SiC substrate which is formed by cutting along (1 1 {overscore (2)} 0) Miller index plane ±10°, said single crystal α-SiC substrate and said polycrystalline β-SiC plate which are superimposed on each other are heat-treated in an inert gas atmosphere, whereby single crystal having a crystal orientation of an orientation of said cutting plane is integrally grown in said polycrystalline β-SiC plate in conformity with said single crystal α-SiC substrate.
