  • Publication number: 20220254820
    Abstract: An apparatus includes pixels on a substrate. Each pixel includes a first portion, a second, and a microlens. The substrate has a first surface on an incidence side and a second surface opposite to the first surface, and includes an inter-pixel portion isolating adjacent pixels from each other, and an intra-pixel portion isolating the first and second portions from each other. The inter-pixel portion includes a first region located adjacently to the first surface, and a second region located adjacently to the second surface. The intra-pixel portion includes a third region located adjacently to the first surface, and a fourth region located adjacently to the second surface. The first and third regions are shifted with respect to the second and fourth regions, respectively, in an identical direction that is a direction orthogonal to a longitudinal direction of the intra-pixel portion in plan view from the first surface.
