Abstract
6H-SiC ingots were grown with different growth interfaces at different rates via the
sublimation method. A model for the step flow growth mechanism is proposed to interpret the
occurrence of 15R-SiC inclusions in the 6H-SiC single crystal. The results show that the 15R-SiC
occurs more easily on the convex and the concave interface than on the slight convex interface and
15R-SiC inclusion also occurs when the growth rate of 6H-SiC exceeds the critical rate of 300 %m/h
with the slight convex interface at the seed temperature 2250°C.
