Abstract: Provided are a method for manufacturing a silicon carbide single crystal, which can suppress conversion of threading edge dislocations into prismatic plane dislocations and conversion of the prismatic plane dislocations into basal plane dislocations; and a silicon carbide single crystal ingot and a silicon carbide wafer, in which conversion from threading edge dislocations into prismatic plane dislocations and conversion from the prismatic plane dislocations into basal plane dislocations have been suppressed. A silicon carbide single crystal is grown on the surface of a seed substrate by a gas method so that a temperature gradient in the radial direction of the seed substrate takes a predetermined value or lower during the growth.

Abstract: Provided are a method for manufacturing a silicon carbide single crystal, and a silicon carbide single crystal ingot which ensure a high crystal growth rate and increase the ratio of conversion from basal plane dislocations to threading edge dislocations. The method prepares a seed substrate composed of silicon carbide having an off-angle in a [1-100] direction with respect to a {0001} plane; and grows a silicon carbide single crystal layer on the seed substrate by an HTCVD method, thereby converting basal plane dislocations contained in the seed substrate to threading edge dislocations during crystal growth.
