Abstract
An image sensor pixel includes a photo-sensor region, a microlens, a first color filter layer, and a second color filter layer. The photo-sensor region is disposed within a semiconductor die. The microlens is disposed on the semiconductor die in optical alignment with the photo-sensor region. The first color filter layer is disposed between the photo-sensor region and the microlens. The second color filter layer is disposed on an opposite side of the microlens as the first color filter layer.
Claims5
A method of fabricating an image sensor array, comprising:
- forming an array of photo-sensors on a die;
- forming an array of first color filters having a color pattern over the array of photo-sensors;
- forming an array of microlenses over the array of first color filters;
- and
- forming an array of second color filters having the color pattern on the array of microlenses, wherein the array of second color filters are concentrically conformed over the array of microlenses.
