Abstract
The present invention is a silicon single crystal substrate for a solid-state image sensor obtained by slicing a silicon single crystal fabricated by a CZ method, where the silicon single crystal substrate is a p-type silicon single crystal substrate whose main dopant is Ga, and the silicon single crystal substrate has a B concentration of 5×10atoms/cmor less. This provides a silicon single crystal substrate and a silicon epitaxial wafer for a solid-state image sensor that can suppress the residual image characteristics of a solid-state image sensor.
