Abstract
In order to provide a photodetection semiconductor device including a light receiving element configured to reduce afterimages, a photodiode is formed by a PN junction into a circular shape so that a uniform distance from an end portion of a light receiving element to an electrode serving as a carrier outlet is realized, to thereby enable carriers to be uniformly taken out from all directions.
