Patent ID: 7816748

Claim:
A semiconductor device in which a light-receiving part and a circuit part are positioned adjacent to one another on a shared semiconductor substrate, the semiconductor device comprising: a silicon oxide film that is formed on and in contact with a surface of the semiconductor substrate; an aperture bottom layer that is layered on and in contact with the silicon oxide film at a position that corresponds to the light-receiving part and is formed from polysilicon; a multilayer wiring-structure layer that is layered above the semiconductor substrate above which the aperture bottom layer is formed and includes metal wiring and an interlayer insulating layer that constitute the circuit part; an apertured part in the wiring-structure layer that is formed in a position of the light-receiving part and penetrates the wiring-structure layer to reach the silicon oxide film; and a moisture-proof film for covering side-wall and bottom surfaces of the apertured part.
