US 10,256,269 B2 · Solid-state imaging element, imaging device, and electronic apparatus

Abstract

The present technology relates to a solid-state imaging element, an imaging device, and an electronic apparatus which enable enhancement of focusing accuracy and sensitivity and suppression of color mixing, in a high image height portion. Incident light is condensed by a main lens, and the condensed light is condensed by a plurality of on-chip lenses. The on-chip lenses are each shared by a plurality of photodiodes that receive the light condensed by the on-chip lens and that generate and accumulate electric charges corresponding to the amounts of light. The plurality of photodiodes sharing the on-chip lens are shaped, in accordance with the image height of the on-chip lens, in such a manner as to have substantially uniform light reception characteristics. The present technology is applicable to a CMOS image sensor.

A solid-state imaging element, comprising:

a main lens configured to condense incident light to generate first condensed light;
a plurality of on-chip lenses configured to condense the first condensed light to generate second condensed light;
and
a plurality of photodiodes that share a first on-chip lens of the plurality of on-chip lenses, wherein the plurality of photodiodes are configured to:
receive the second condensed light;
generate a plurality of electric charges based on an amount of the incident light;
and
accumulate the plurality of electric charges,
wherein a shape of each the plurality of photodiodes that share the first on-chip lens is based on a distance of the first on-chip lens from an image height center, and wherein the image height center is on an optical axis of the main lens.
