Patent ID: 8232132

Claim:
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, wherein forming the array of second color filters having the color pattern on the array of microlenses includes: forming a first blanket color filter layer over the image sensor array having a first color; patterning the first blanket color filter layer to form a first portion of the array of second color filters having the first color; forming a second blanket color filter layer over the image sensor array having a second color; patterning the second blanket color filter layer to form a second portion of the array of second color filters having the second color; forming a third blanket color filter layer over the image sensor array having a third color; and patterning the third blanket color filter layer to form a third portion of the array of second color filters having the third color.
