摘要:
When an SiC single crystal having a large diameter of a {0001} plane is produced by repeating a-plane growth, the a-plane growth of the SiC single crystal is carried out so that a ratio Sfacet (=S1×100/S2) of an area (S1) of a Si-plane side facet region to a total area (S2) of the growth plane is maintained at 20% or less.
