Abstract:
1. A solid-state imaging device comprising: a pixel array area including pixels arranged in a well region in a two-dimensional array fashion, each of the pixels including: a photoelectric conversion portion including an activation region; a reading portion for reading a signal photo-electrically converted by the photoelectric conversion portion; and an amplifying portion for amplifying the signal read by the reading portion; and well potential fixing parts each provided adjacent a corresponding activation region of the photoelectric conversion portion for the corresponding pixel, the well potential fixing parts fixing the respective wells at a predetermined potential, and wherein the well potential fixing part is immediately adjacent its corresponding activation region; and further 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 above 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.
