Abstract:
A silicon carbide substrate includes a carbon-surface-side principal surface and a silicon-surface-side principal surface. The silicon carbide substrate has a diameter of 100 mm or greater and a thickness of 300 μm or greater. An off angle of the carbon-surface-side principal surface and the silicon-surface-side principal surface relative to a {0001} plane is smaller than or equal to 4°. A nitrogen concentration in the carbon-surface-side principal surface is higher than a nitrogen concentration in the silicon-surface-side principal surface, and a difference in Raman peak shift between the carbon-surface-side principal surface and the silicon-surface-side principal surface is smaller than or equal to 0.2 cm −1 .

Claim (Index 3):
The silicon carbide substrate as claimed in  claim 1 , wherein a difference between the nitrogen concentration in the carbon-side principal surface and the nitrogen concentration in the silicon-side principal surface is smaller than or equal to 1\u00d710 17  cm \u22123 .
