Patent ID: 7821092

Claim:
A semiconductor device in which a photoreceptor part and a circuit part are arranged adjacent to each other on a shared semiconductor substrate, the semiconductor device comprising: an electrode region that is a diffusion layer region formed in a surface of the semiconductor substrate at the photoreceptor part, and that gathers signal charges generated by light incident on the photoreceptor part; a wiring structure layer that is layered over the semiconductor substrate, and that includes an interlayer insulation film; an open portion of the wiring structure layer, formed in a position of the photoreceptor part; and a partition wall composed of a metal material that is formed within the wiring structure layer adjacent to the open portion, along a boundary of the photoreceptor portion with the circuit portion, wherein the electrode region has an extended portion that extends farther to an outside than the boundary, the wiring structure layer has a first wiring which is separate from the partition wall and via which the signal charges are read from the electrode region to the circuit portion, and the first wiring is electrically connected with the electrode region at the extended portion.
