Patent ID: 7804116

Claim:
A solid-state imaging device comprising: a pixel array area including pixels arranged in second conductivity type well regions in a two-dimensional array fashion, each of the pixels including: a photoelectric conversion portion including an activation region; and well potential fixing parts for fixing the second conductivity type well regions at a predetermined potential; wherein the photoelectric conversion portion includes a first impurity region of a first conductivity type and a second impurity region of a second conductivity type provided over the first impurity region, and wherein the well potential fixing parts have an activation region connected to a metal wiring from an upper portion of the second conductivity type well region and a third impurity region of second conductivity type, wherein: the photoelectric conversion portion includes a first impurity region of a first conductivity type and a second impurity region of a second conductivity type provided on the first impurity region; and each of the well potential fixing parts includes an impurity region of the second conductivity type whose density is higher than the second impurity region.
