Patent attributes
The present technology relates to a solid-state imaging device and an electronic apparatus capable of improving sensitivity while suppressing deterioration of color mixing. The solid-state imaging device includes a substrate, a first photoelectric conversion region in the substrate, a second photoelectric conversion region in the substrate, a trench between the first photoelectric conversion region and the second photoelectric conversion region and penetrates through the substrate, a first concave portion region that has a plurality of concave portions provided on a light receiving surface side of the substrate, above the first photoelectric conversion regions, and a second concave portion region that has a plurality of concave portions provided on the light receiving surface side of the substrate, above the second photoelectric conversion region. The technology of the present disclosure can be applied to, for example, a backside illumination solid-state imaging device and the like.
