Abstract:
1. A photoelectric conversion device comprising: a first-conductivity type first semiconductor region located in a pixel region; a second-conductivity type second semiconductor region provided in the first semiconductor region and capable of accumulating photoelectric carriers in a floating state, wherein said first and second semiconductor regions form a photodiode; a wiring for electrically connecting directly the second semiconductor region to a circuit element located outside the pixel region; and a conductor maintained at a predetermined potential and disposed over one side of said wiring within the pixel region, wherein an insulator is inserted between said conductor and said wiring so that said conductor does not contact said wiring, and the one side of said wiring is opposite to a side of said wiring at which said wiring is connected to said second semiconductor region, and, wherein said conductor is formed in the same layer as a light-screening layer in said pixel region.
