Abstract:
1. A backside illumination solid-state imaging device comprising: a semiconductor layer; a first light-receiving unit and a second light-receiving unit which are formed adjacent to each other in the semiconductor layer, convert light applied from a lower surface side of the semiconductor layer into a signal, and store electric charges; a circuit unit which is formed on an upper surface of the semiconductor layer and reads electric charges stored in the first light-receiving unit and the second light-receiving unit; an impurity isolation layer which is formed to reach to the upper surface from the lower surface in the semiconductor layer and isolates the first light-receiving unit from the second light-receiving unit; and a light-shielding film which is formed on part of the lower surface side in the impurity isolation layer so as to extend from the lower surface to the upper surface.
