Abstract:
In a method for fabricating a semiconductor substrate according to an embodiment, an SiC substrate is formed by vapor growth and C (carbon) is introduced into the surface of the SiC substrate to form an n-type SiC layer on the SiC substrate by an epitaxial growth method.

Claim (Index 6):
A semiconductor device comprising:\n an SiC substrate having a region where a Z 1/2  level density measured by DLTS (Deep Level Transient Spectroscopy) is 1\u00d710 11  cm \u22123  or less and an n-type SiC layer provided on the SiC substrate, the n-type SiC layer having an impurity concentration of an n-type impurity lower than an impurity concentration of the n-type impurity and a p-type impurity of the SiC substrate.
