Abstract

Method, apparatus, and/or system providing a backside illuminated imaging device. A non-planar metallic or otherwise reflective layer is provided in an image pixel cell at the frontside of the device substrate to capture radiation passing through the device substrate. The non-planar surface is formed to be capable of reflecting substantially all such radiation back to a photosensor located in the same pixel cell.
