Abstract:
A semiconductor photodetector includes a semiconductor substrate including a silicon substrate. The semiconductor substrate includes a second main surface as a light incident surface and a first main surface opposing the second main surface. In the semiconductor substrate, carriers are generated in response to incident light. A plurality of protrusions is formed on the second main surface. The protrusion includes a slope inclined with respect to a thickness direction of the semiconductor substrate. At the protrusion, a (111) surface of the semiconductor substrate is exposed as the slope. The height of the protrusion is equal to or more than 200 nm.

Claim (Index 2):
The semiconductor photodetector according to  claim 1 ,\n wherein a semiconductor region having a conductivity type different from that of the silicon substrate is provided on the back surface side of the silicon substrate, an accumulation layer is provided on the light incident surface side of the silicon substrate, and the slope of the protrusion is included in a surface of the accumulation layer.
