Abstract
A photoelectric conversion apparatus includes a plurality of units each including a charge generation region disposed in a semiconductor layer. Each of a first unit and a second unit of the plurality of units includes a charge storage region configured to store charges transferred thereto from the charge generation region, a dielectric region located above the charge generation region and surrounded by an insulator layer, and a first light-shielding layer covering the charge storage region that is located between the insulator layer and the semiconductor layer, and the first light-shielding layer having an opening located above the charge generation region. The charge generation region of the first unit is able to receive light through the opening of the first light-shielding layer. The charge generation region of the second unit is covered with a second light-shielding layer.
