Photoelectric conversion element, photoelectric conversion apparatus using the same, distance detection sensor, and information processing system

A photoelectric conversion element comprising:

• a first photoelectric conversion unit configured to generate an electron;
• a second photoelectric conversion unit configured to generate a hole;
• a first floating diffusion region to which the electron generated in the first photoelectric conversion unit is transferred;
• a second floating diffusion region to which the hole generated in the second photoelectric conversion unit is transferred;
• an amplifying transistor including a gate electrically connected to the first floating diffusion region and the second floating diffusion region;
• a first charge ejection unit to which the electron generated in the first photoelectric conversion unit is ejected, the first charge ejection unit being arranged outside a position between the first photoelectric conversion unit and the first floating diffusion region;
• and
• a second charge ejection unit to which the hole generated in the second photoelectric conversion unit is ejected, the second charge ejection unit being arranged outside a position between the second photoelectric conversion unit and the second floating diffusion region,
• wherein the first photoelectric conversion unit and the second photoelectric conversion unit are arranged along a principal surface of a semiconductor substrate.
