Abstract
A solid-state imaging device includes a plurality of pixels two-dimensionally arranged on a semiconductor substrate. Each of the pixels includes at least one shallow light receiving portion formed near a surface of the semiconductor substrate and at least one deep light receiving portion formed under the shallow light receiving portion. One or more of the shallow light receiving portions and the deep light receiving portion are connected to each other so as to form a second light receiving portion. The rest of the shallow light receiving portions forms a first light receiving portion. Excess electric charge in the first light receiving portion is discharged to the deep light receiving portion.
