Abstract: Provided is a method in which the rate of growth is lowered even when a cut SiC seed crystal is used in performing MSE process. A SiC seed crystal that is used as a seed crystal in metastable solvent epitaxy process (MSE process) is heated under Si atmosphere and the surface of the SiC seed crystal is etched to remove a work-affected layer that was formed by cutting. Work-affected layers generated on SiC seed crystals are known to inhibit growth during MSE process, and therefore removing the work-affected layers can prevent lowering of the rate of growth.

The end surface walls are respectively provided at one end and the other end of the outer peripheral wall. The reaction container is arranged in a heat-insulating cover such that an axis of the outer peripheral wall is in parallel with a horizontal direction. The outer peripheral wall has an inner peripheral surface rotationally symmetric with respect to the axis. During the powder process, the powder is stored in the reaction container, and the reaction container is rotated around a rotation axis that passes through the central axis of the outer peripheral wall by the rotation driving device.
