Claim Text:
1. An image pickup apparatus comprising: a semiconductor substrate; a first photoelectric conversion unit that is disposed in the semiconductor substrate, is configured to accumulate charges, and is of a first conductivity type; a second photoelectric conversion unit that is disposed in the semiconductor substrate, is configured to accumulate charges, and is of the first conductivity type; an electrode that is disposed on a region between the first photoelectric conversion unit and the second photoelectric conversion unit and is configured to control an electrical conduction between the first photoelectric conversion unit and the second photoelectric conversion unit; a first semiconductor region that is disposed under the electrode and between the first photoelectric conversion unit and the second photoelectric conversion unit, is continuous from the first photoelectric conversion unit to the second photoelectric conversion unit, and is of the first conductivity type; and a second semiconductor region that is disposed under the electrode and between the first photoelectric conversion unit and the second photoelectric conversion unit, is provided at a depth different from that of the first semiconductor region, and is of a second conductivity type, wherein a boundary between the first semiconductor region and the second semiconductor region is located between a surface of the semiconductor substrate and a depth at which an impurity concentration peak of the first photoelectric conversion unit is provided.
