Nitride semiconductor substrate
First Claim
Patent Images
1. A nitride semiconductor substrate, comprising:
- a first surface forming a principal surface of the substrate;
a first edge formed by beveling at least a portion of an edge of the first surface of the substrate; and
a scattering region formed in at least a portion of the first edge, the scattering region scattering more external incident light than the first surface,wherein a boundary is formed between the first surface and the scattering region due to a difference between a surface roughness of the first surface and a surface roughness of the scattering region.

Abstract
A nitride semiconductor substrate has a first surface forming a principal surface of the substrate. A first edge is formed by beveling at least a portion of an edge of the first surface of the substrate. A scattering region is formed in at least a portion of the first edge. The scattering region scatters more external incident light than the first surface.
