Abstract
A light receiving element including: a semiconductor substrate; a photoelectric conversion unit (PD) in the semiconductor substrate that converts light into electric charges; a first electric charge accumulation unit (MEM) in the semiconductor substrate to which the electric charges are transferred from the photoelectric conversion unit; a first distribution gate on a front surface of the semiconductor substrate that distributes the electric charges from the photoelectric conversion unit to the first electric charge accumulation unit; a second electric charge accumulation unit (MEM) in the semiconductor substrate to which the electric charges are transferred from the photoelectric conversion unit; and a second distribution gate on the front surface of the semiconductor substrate that distributes the electric charges from the photoelectric conversion unit to the second electric charge accumulation unit, in which the first and second distribution gates each have a pair of buried gate portions.
