ABSTRACT:
A color imager, which has a plurality of photodiodes, utilizes a layer of metal that is formed over the photodiodes. The metal layer has a plurality of different sized openings that lie vertically over the photodiodes to physically diffract, and thereby filter, the incident light that strikes the color imager.
