| 简介 |
A manufacturing method of a SiC single crystal includes a first growth process and a re-growth process. In the first growth process, a first seed crystal made of SiC is used to grow a first SiC single crystal. In the re-growth process, a plurality of growth steps is performed for (n−1) times. In a k-th growth step, a k-th seed crystal is cut out from a grown (k−1)-th SiC single crystal, and the k-th seed crystal is used to grow a k-th SiC single crystal (n≧2 and 2≰k≰n). When an offset angle of a growth surface of the k-th seed crystal is defined as θk, at least in one of the plurality of growth steps, the offset angle θk is smaller than the offset angle θk−1. |
