Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate; and a plurality of pixels arranged on the semiconductor substrate, each of the pixels including a light receiving region for receiving an incident light, wherein a group of a predetermined number of the pixels constitutes one pixel unit, each of the pixels includes a photoelectric conversion region, a light shielding film, and a gate electrode, the photoelectric conversion region is formed to as to extend to a region under the gate electrode, the gate electrode partially includes a region through which the incident light cannot pass, the light receiving region is defined by an opening of the light shielding film, a region in which the photoelectric conversion region is projected onto the main surface of the semiconductor substrate, and a region, including in the main surface of the semiconductor substrate, through which the incident light can pass, the light receiving region is formed such that a center thereof coincides with a center of each of the pixels in a direction parallel to the main surface of the semiconductor substrate, and a deepest point of the photoelectric conversion region is at the gate electrode side relative to the center of the light receiving region.
