Patent ID: 8390088

Claim:
A photoelectric conversion device having an effective region in which a photoelectric conversion unit is not shielded against light, and a light-shielded region including a driving circuit, the device comprising: a semiconductor substrate in which the photoelectric conversion unit in the effective region and the driving circuit are arranged; and a multilayer wiring structure, which is arranged on the semiconductor substrate and includes: an interlayer insulation film arranged in the effective region and the light-shielded region, wherein the interlayer insulation film extends from the effective region into the light-shielded region, a first wiring layer arranged on the interlayer insulation film, wherein the first wiring layer serves as a top wiring layer in the effective region and includes aluminum as a principal component, a first insulation film arranged in the effective region and the light-shielded region so as to cover the first wiring layer and the interlayer insulation film, wherein the first insulation film extends from the effective region into the light-shielded region, and a second wiring layer, which serves as a top wiring layer arranged on the first insulation film in the light-shielded region and which includes aluminum as a principal component, wherein the first insulation film includes, in the effective region, a first portion that is positioned above the photoelectric conversion unit and that functions as at least a part of an interlayer lens.
