Abstract
An image sensor array includes a substrate having at least three image sensors located therein. The image sensor array also includes a blue filter positioned proximate to the first image sensor; a green filter proximate to the second image sensor; and a red filter proximate to the third image sensor. A first microlens is positionally arranged with the blue filter and the first image sensor; a second microlens is positionally arranged with the green filter and the second image sensor; and a third microlens is positionally arranged with the red filter and the third image sensor. The first microlens has a larger effective area than the second microlens, and the second microlens has a larger effective area than the third microlens.
Claims20
An image sensor array, comprising:
- a substrate having a plurality of image sensors located therein;
- and
- a microlens layer comprising at least a first, second, and third microlens located over the substrate, each of the plurality of microlenses including a convex portion aligned over a corresponding one of the plurality of image sensors,
- wherein the first, second, and third microlenses of the microlens layer have different effective areas, wherein the first and second microlenses are adjacent each other, and wherein the second microlens is next to the third microlenses and there is a gap between the second and third microlenses.
An image sensor array, comprising:
- a substrate having at least three image sensors located therein;
- a blue filter positioned proximate to the first image sensor, a green filter proximate to the second image sensor, and a red filter proximate to the third image sensor;
- a first microlens positionally arranged with the blue filter and the first image sensor, a second microlens positionally arranged with the green filter and the second image sensor, and a third microlens positionally arranged with the red filter and the third image sensor;
- wherein the first microlens has a larger effective area than the second microlens, and the second microlens has a larger effective area than the third microlens.
An image sensor array, comprising:
- a substrate having at least three image sensors located therein;
- a first color filter positioned proximate to the first image sensor, a second color filter proximate to the second image sensor, and a third color filter proximate to the third image sensor;
- a first microlens positionally arranged with the first color filter and the first image sensor, a second microlens positionally arranged with the second color filter and the second image sensor, and a third microlens positionally arranged with the third color filter and the third image sensor,
- wherein the first and second microlenses are closely adjacent each other, wherein the second microlens is next to the third microlens, wherein there is a gap between the second and third microlenses, and wherein the gap is defined using optical proximity correction.
