Patent ID: 7993453

Claim:
A method for the production of an SiC single crystal, comprising the steps of: growing a first SiC single crystal in a first direction of growth on a first seed crystal formed of an SiC single crystal; disposing the first SiC single crystal grown on the first seed crystal in a direction parallel or oblique to the first direction of growth and cutting the disposed first SiC single crystal in a direction of a major axis in a cross section perpendicular to the first direction of growth to obtain a second seed crystal; using the second seed crystal to grow thereon in a second direction of growth a second SiC single crystal to a thickness greater than a length of the major axis in the cross section; disposing the second SiC single crystal grown on the second seed crystal in a direction parallel or oblique to the second direction of growth and cutting the disposed second SiC single crystal in a direction of a major axis in a cross section perpendicular to the second direction of growth to obtain a third seed crystal; using the third seed crystal to grow thereon a third SiC single crystal; and cutting the third SiC single crystal grown on the third seed crystal in such a manner as to expose a {0001} crystal face, thereby obtaining an SiC single crystal.
