Patent ID: 8598640

Claim:
A solid-state imaging device comprising: a light-receiving sensor portion having a photoelectric conversion region, the photoelectric conversion region including a first-conductivity-type semiconductor region and a second-conductivity-type semiconductor region, the second-conductivity-type semiconductor region being on a surface of the first-conductivity-type semiconductor region: an electrode to transfer a signal charge obtained from the light-receiving sensor portion; a light-shielding film covering an image pickup area, including the electrode, except the light-receiving sensor portion; and a voltage-applying portion separate from the light-shielding film, the voltage-applying portion positioned under the light-shielding film and spaced from the light-shielding film and the electrode by an insulation film, wherein, the photoelectric conversion region further includes a low impurity region that is on the surface of said first-conductivity-type region with the second-conductivity-type semiconductor region and that is in contact with the second-conductivity-type semiconductor region, the low impurity region having an impurity concentration that is lower than that of the second-conductivity-type semiconductor region, and the voltage applying portion applies a voltage to the low impurity region to control a potential of the low impurity region, wherein the voltage-applying portion is not disposed above the electrode.
