  • Publication number: 20230246048
    Abstract: Incident light transmitted through a semiconductor substrate is shielded at a boundary between pixels. An imaging element is provided with a pixel, a front surface side light shielding unit, and a back surface side light shielding unit. The pixel is provided with a photoelectric conversion unit that is arranged in a semiconductor substrate on a front surface side of which a wiring region is formed and performs photoelectric conversion of incident light applied from a back surface side of the semiconductor substrate. The front surface side light shielding unit is embedded on the front surface side of the semiconductor substrate at the boundary between the pixels to shield the incident light.
