Claim Text:
1. A semiconductor image pickup device comprising a pixel area including a plurality of pixels arranged in a matrix and a non-pixel area arranged outside the pixel area, the device comprising: a semiconductor substrate; a first photoelectric conversion element formed in the pixel area on the semiconductor substrate; a first transistor formed in the pixel area and connected to the first photoelectric conversion element; a second photoelectric conversion element formed in the non-pixel area on the semiconductor substrate; a second transistor formed in the pixel area and connected to the first photoelectric conversion element; a first interlayer insulating film formed on the semiconductor substrate; a metal contact formed through the first interlayer insulating film and in contact with the semiconductor substrate; a first metal wire formed on the first interlayer insulating film and connected to the metal contact; a second interlayer insulating film formed on the first metal wire; a dummy via wire formed in the non-pixel area, formed directly above and to face the non-pixel area, penetrating the second interlayer insulating film, and connected to the first metal wire; and a second metal wire formed over the dummy via wire and connected to an upper end of the dummy via wire.
