ABSTRACT:
A pixel for use in CMOS or CCD image sensors is disclosed. The pixel includes a light sensitive element, such as a photodiode, formed in a semiconductor substrate. An anti-reflective coating is formed over the photodiode to reduce reflection of incident light. The reduced reflection results in greater “signal” reaching the photodiode.
