Original Abstract Submitted
a photoelectric conversion apparatus including an avalanche photodiode is provided. the photoelectric conversion apparatus includes an oxide film disposed on a semiconductor layer and a member provided on the oxide film. the member is disposed to overlap at least a boundary between a first semiconductor region and a third semiconductor region in plan view. the work function of the member differs from the work function of each of the first semiconductor region and the third semiconductor region so that a potential gradient for signal charge is generated in a depth direction of the semiconductor layer at at least the boundary.
