Abstract
At least one single crystal substrate, each having a backside surface and made of silicon carbide, and a supporting portion having a main surface and made of silicon carbide, are prepared. In this preparing step, at least one of the backside surface and main surface is formed by machining. By this forming step, a surface layer having distortion in the crystal structure is formed on at least one of the backside surface and main surface. The surface layer is removed at least partially. Following this removing step, the backside surface and main surface are connected to each other.
