SIC SINGLE CRYSTAL, SIC WAFER, AND SEMICONDUCTOR DEVICE

摘要

An SiC single crystal having at least one orientation region where a basal plane dislocation has a high linearity and is oriented to three crystallographically-equivalent <11-20> directions, and an SiC wafer and a semiconductor device which are manufactured from the SiC single crystal. The SiC single crystal can be manufactured by using a seed crystal in which the offset angle on a {0001} plane uppermost part side is small and the offset angle on an offset direction downstream side is large and growing another crystal on the seed crystal.
