Abstract:
1. A photoelectric conversion device including a pixel region, the device comprising: a photoelectric converter arranged in the pixel region; a transfer MOS transistor arranged in the pixel region for transferring charges generated by the photoelectric converter to a floating diffusion; a first film continuously arranged to cover the photoelectric converter and a first region of an upper surface of a gate electrode of the transfer MOS transistor, the first film being an insulating film; a second film continuously arranged to cover the floating diffusion and a second region of the gate electrode of the transfer MOS transistor, the second film being an insulating film; and a contact plug connected with the floating diffusion through the second film, wherein the first film and the second film do not overlap each other on the upper surface of the gate electrode of the transfer MOS transistor.
