Abstract
An imager, including: a semiconductor substrate; a plurality of spaced image pixels formed in the substrate; and a dielectric layer formed over the image pixels, the dielectric layer having a top surface. The imager further includes a plurality of depressions formed in the top surface; and a plurality of lenses having top surfaces, each lens formed in the depression corresponding to an underlying image pixel, the top surface of each lens being optically planar with the top surface of the dielectric.
