Patent ID: 7821093

Claim:
A solid-state imaging device comprising: a light-receiving sensor portion having a photoelectric conversion region, the photoelectric conversion region includes a first-conductivity-type semiconductor region and a second-conductivity-type semiconductor region; a low impurity region containing a lower impurity concentration than that of said second-conductivity-type semiconductor region, the low impurity region being positioned on a surface of said first-conductivity-type semiconductor region; an electrode to read a signal charge from the light-receiving sensor portion; and a light-shielding film covering an image pickup area except said light-receiving sensor portion, the light-shielding film being subject to a voltage signal from a power source electrically connected to the light-shielding film, wherein, the second-conductivity-type semiconductor region is centered on a surface of the first-conductivity-type semiconductor region, the low impurity region is located in contact with the second-conductivity-type semiconductor region.
