Abstract
Provided is a light receiving element capable of improving a transfer failure in a structure in which a photoelectric converter is embedded. A light receiving element includes a photoelectric conversion region of a first conductivity type, a well region of a second conductivity type provided on a side of one surface of the photoelectric conversion region, a floating diffusion region of the first conductivity type provided on a side of a one surface of the well region opposite to the photoelectric conversion region, a transfer gate electrode that is embedded in a depth direction of the well region with a gate insulating film interposed therebetween and transfers a signal charge photoelectrically converted in the photoelectric conversion region to the floating diffusion region, and an auxiliary electrode that is embedded in the well region with the gate insulating film interposed therebetween and extends toward a side surface of the transfer gate electrode.
