Abstract:
1. A photoelectric conversion device comprising: a photoelectric conversion unit arranged in a semiconductor substrate; a charge holding portion arranged in the semiconductor substrate; a first transfer electrode arranged at a position above the charge holding portion; a charge-voltage converter arranged in the semiconductor substrate; a second transfer electrode arranged at a position above the semiconductor substrate and between the charge holding portion and the charge-voltage converter; an insulation film arranged to cover the first and second transfer electrodes; a first transfer control line for controlling the first transfer electrode, the first transfer control line being arranged above the insulation film; a second transfer control line for controlling the second transfer electrode, the second transfer control line being arranged above the insulation film; and a light-shielding film arranged between the insulation film and a plane on which at least one of the first and second transfer control lines is arranged, wherein the light-shielding film extends from a position above the first transfer electrode to a position above the second transfer electrode, and wherein (a) the light-shielding film is electrically connected to the first transfer electrode and the first control line, and electrically disconnected from the second transfer electrode and the second control line, or (b) the light-shielding film is electrically connected to the second transfer electrode and the second control line, and electrically disconnected from the first transfer electrode and the first control line.
