Abstract
A solid-state imaging device includes: a first lens layer; and a second lens layer, wherein the second lens layer is formed at least at a periphery of each first microlens formed based on the first lens layer, and the second lens layer present at a central portion of each of the first microlenses is thinner than the second lens layer present at the periphery of the first microlens or no second lens layer is present at the central portion of each of the first microlenses.
Claims21
An imaging device comprising a micro lens comprising:
- a first lens layer comprising a plurality of first micro lenses with inter pixel gaps therebetween;
- and
- a second lens layer above the first lens layer;
- wherein a thickness of the second lens layer at a central portion of one of the first micro lenses in the plurality of first micro lenses is less than a thickness of the second lens layer at a periphery of the one of the first micro lenses and throughout an inter pixel gap;
- and
- wherein an inter pixel gap in an opposite side direction is smaller than an inter pixel gap in a diagonal direction.
