LIGHT-RECEIVING ELEMENT AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/095491

A1

Provided is a light-receiving element capable of suppressing mismatch between taps and degradation of signal separation performance due to movement delay of electrons. A light-receiving element has a plurality of pixels. Each of the plurality of pixels has a photoelectric conversion unit that receives and photoelectrically converts incident light, and a plurality of storage units to which electrons generated by the photoelectric conversion unit are transferred via respective transfer transistors, and the transfer destination of the electrons is selected from the plurality of storage units and switched. Each of the plurality of pixels is provided with an inter-pixel isolation portion having an insulating film that is formed at least partly in the depth direction from the light incident surface of the pixel to the surface opposite to the light incident surface and at least partly insulates and blocks light between adjacent pixels. The inter-pixel isolation portion is configured to have a thickness toward the inside of the pixel so that at least a portion of each of a plurality of transfer transistors overlaps with at least a portion of the inter-pixel isolation portion in a plan view.
