Patent ID: 7830433

Claim:
An amplification type solid state imaging device comprising: a light-receiving portion formed by arranging on a semiconductor substrate one-dimensionally or two-dimensionally a plurality of pixels that convert incident light to signal charge and output electric signals corresponding to the amount of the signal charge, a reader for reading out sequentially the electric signals from the respective pixels, a noise rejection circuit for suppressing spurious signals for the electric signals read out by the reader, and a first light-shielding layer positioned on the upper part of the light-receiving portion so as to restrict entry of tight into the light-receiving portion other than a part for photoelectric conversion; wherein a second light-shielding layer for restricting entry of tight into the noise rejection circuit is provided on the upper part of the noise rejection circuit; the first light-shielding layer and the second light-shielding layer have electroconductivity, wirings are connected to the first light-shielding layer and the second light-shielding layer respectively, different signal voltages are applied respectively to the wiring connected to the first light-shielding layer and the wiring connected to the second light-shielding layer; and the amplification type solid state imaging device comprises further a third light-shielding layer formed in a spacing between the light-receiving portion and the noise rejection circuit, as a layer below the first light-shielding layer and the second light-shielding layer, so that the third light-shielding layer overlaps partially with the first light-shielding layer and the second light-shielding layer in a direction of thickness of the semiconductor substrate.
