Abstract
A photosensitive region includes a semiconductor substratemade of a P-type semiconductor, and N-type semiconductor regionsandformed on the surface of the semiconductor substrateAccordingly, the first photosensitive portion includes a portion of the semiconductor substrateand the semiconductor regions, thus configuring a photodiode. The photosensitive region on one side contained in the second photosensitive region includes a portion of the semiconductor substrateand the semiconductor regionsthus configuring a photodiode. The photosensitive region on the other side contained in the second photosensitive region includes a portion of the semiconductor substrateand the semiconductor regions, thus configuring a photodiode. Each of the semiconductor regionsandis in a shape of an approximate triangle, and is formed so that one side of the regionsis adjacent to one side of the regionand vice versa, in one pixel.
