Abstract:
1. A photoelectric conversion device comprising: a photoelectric conversion unit which is arranged in a semiconductor substrate; a charge holding portion which is arranged in the semiconductor substrate and temporarily holds a charge generated by the photoelectric conversion unit; a first transfer electrode which is arranged at a position above the semiconductor substrate to transfer a charge generated by the photoelectric conversion unit to the charge holding portion; a charge-voltage converter which is arranged in the semiconductor substrate and converts a charge into a voltage; a second transfer electrode which is arranged at a position above the semiconductor substrate to transfer a charge held by the charge holding portion to the charge-voltage converter; transfer control lines for controlling the first and second transfer electrodes; an insulation film arranged to cover the first transfer electrode and the second transfer electrode; and a light-shielding film arranged between the insulation film and a plane on which the transfer control lines are arranged, wherein the light-shielding film extends from a position above the first transfer electrode to a position above the second transfer electrode, wherein the first transfer electrode is arranged to cover the charge holding portion so as to optically shield the charge holding portion, and not to overlap the second transfer electrode.
