Abstract:
A reference sample ( 41 ) has a step/terrace structure made of monocrystalline SiC and a surface of each terrace has first or second stack orientation. In the reference sample ( 41 ), contrast as difference in lightness and darkness between an image of a terrace with a surface directly under which the first stack orientation lies and an image of a terrace with a surface directly under which the second stack orientation lies changes according to an incident electron angle which is an angle that an electron beam emitted from a scanning electron microscope forms with a perpendicular to the terrace surface. Even when a SiC substrate has an off angle (e.g., from 1° to 8°), using an inclined support base ( 20 a ) capable of correcting the off angle enables sharp contrast that reflects difference between the first and second stack orientations directly under the surface to be obtained irrespective of the off angle.

Claim (Index 10):
The method for evaluating a SiC substrate according to  claim 9 , wherein\n quality of a SiC substrate is evaluated by comparing in-plane distribution of brightness that is obtained by an electron beam being emitted from a scanning electron microscope to the reference sample at a predetermined incident electron angle and that is obtained from terraces with surfaces directly under which a first stack orientation and a second stack orientation lie against in-plane distribution of brightness that is obtained by an electron beam being emitted to a SiC substrate to be evaluated at an incident electron angle identical to the incident electron angle.
