  • Publication number: 20220165770
    Abstract: A solid-state imaging device according to the present disclosure includes a semiconductor layer, a plurality of on-chip lenses, a first separation region, and a second separation region. The semiconductor layer is provided with a plurality of photoelectric conversion units. The plurality of on-chip lenses causes light (L) to be incident on the corresponding photoelectric conversion units. The first separation region separates the plurality of photoelectric conversion units on which the light (L) is incident through the same on-chip lens. The second separation region separates the plurality of photoelectric conversion units on which light is incident through the different on-chip lenses. In addition, the first separation region has a higher refractive index than the second separation region.
