Abstract:
1. A photoelectric conversion device comprising: a semiconductor substrate that includes a first region receiving light and containing a plurality of photoelectric converters and a second region that is shielded from light; a multilayer wiring structure arranged on the semiconductor substrate and including a first wiring layer, an interlayer insulation film arranged to cover the first wiring layer, and a second wiring layer arranged on the interlayer insulation film, wherein the second wiring layer is thinner than the first wiring layer; a passivation film arranged to cover the second wiring layer and the interlayer insulation film; an interlayer lens arranged on the passivation film in the first region in which the second wiring layer is not arranged, with the interlayer lens being arranged at a level where the second wiring layer is arranged, and no interlayer lens being arranged in the second region in which the second wiring layer is arranged, and with a top face of the interlayer lens and a top face of the passivation film in the second region being almost the same height level; and a planarized layer arranged to cover the second wiring layer and the interlayer lens.
