摘要：
System and method for providing a light shield for a CMOS imager is provided. The light shield comprises a structure formed above a point between a photo-sensitive element and adjacent circuitry. The structure is formed of a light-blocking material, such as a metal, metal alloy, metal compound, or the like, formed in dielectric layers over the photo-sensitive elements.
