Abstract:
An SiC single crystal ingot including a silicon carbide (SiC) single crystal formed on a seed crystal, a crystal growth end of a front end of the ingot having a convex shape. An SiC single crystal substrate cut out from a part of a relative height in a height direction of the ingot of at least 0.2 to 0.8 in range has a basal plane dislocation density and threading screw dislocation density observed at the surface of the substrate that are respectively predetermined values or less. Further, the Raman index of the difference (A/B) of the Raman Shift value (A) measured at the center part of the substrate and the Raman Shift value (B) measured at the peripheral parts is a predetermined value or less.

Claim (Index 9):
The SiC single crystal ingot according to  claim 1 , wherein a difference in height (O-E) between a center point O of a crystal growth end corresponding to a position of the ingot height and an edge point E on the crystal growth end corresponding to a position inside from a side surface of the ingot by 10% of the diameter is 1 mm to 7 mm.
