Abstract

A sonar cell provided by the present invention comprises: a p-type diffusion layer (2) formed on a light receiving side (1A), which is a first main surface, of an n-type single crystal silicon substrate (1); a n-type diffusing layer (5) formed on a back side (1B), which is a second main surface, oppositing to the light-receiving side (1A); a light receiving side electrode (4) coupled to the p-type diffusing layer (2); and a back side electrode (7) coupled to the n-type diffusing layer (5). The p-type diffusing layer (2) comprises: a first region (R1) having a first diffusing depth; a second region (R2), disposed as a strip-like structure along the periphery of the semiconductor substrate to surround the first region (R1) and the diffusing depth of the first dopant is deeper than the first region (R1). A sonar cell of reverse bias with low leaking can be thus obtained.
