Manufacturing method of silicon carbide single crystal

Abstract

In a manufacturing method of a silicon carbide single crystal, a seed crystal made of silicon carbide is prepared. The seed crystal has a growth surface and a stacking fault generation region and includes a threading dislocation that reaches the growth surface. The growth surface is inclined at a predetermined angle from a (0001) plane. The stacking fault generation region is configured to cause a stacking fault in the silicon carbide single crystal when the silicon carbide single crystal is grown. The stacking fault generation region is located at an end portion of the growth surface in an offset direction that is a direction of a vector defined by projecting a normal vector of the (0001) plane onto the growth surface. The seed crystal is joined to a pedestal, and the silicon carbide single crystal is grown on the growth surface of the seed crystal.
