Patent ID: 8415664

Claim:
A semiconductor device comprising: a light-transmitting substrate; a transistor over the substrate, the transistor comprising a source, a drain, a gate electrode, and a channel portion; a color filter over the substrate; a photoelectric conversion layer over the substrate, the photoelectric conversion layer including a first semiconductor layer of one conductivity type, a second semiconductor layer, and a third semiconductor layer of an opposite conductivity type from that of the first semiconductor layer; an insulating layer interposed between the color filter and the photoelectric conversion layer; an electrically conductive light-shielding layer overlapping with an end portion of the photoelectric conversion layer, and in electrical contact with the photoelectric conversion layer and one of the source and the drain of the transistor; and another electrically conductive light-shielding layer interposed between the substrate and a second end portion of the photoelectric conversion layer, and made from a same material as the gate electrode of the transistor.
