Abstract
An image sensor in accordance with embodiments disclosed herein includes an array of imaging pixels, an insulator layer, and a plurality of metal reflectors. The array of imaging pixels are disposed within a semiconductor layer, where each imaging pixel in the array of imaging pixels includes a photosensitive element configured to receive light from a backside of the image sensor. The insulator layer is disposed on a frontside of the semiconductor layer and the plurality of metal reflectors are disposed within the insulator layer to reflect the light to a respective photosensitive element. A width of each of the plurality of metal reflectors is equal to a width of a metal reflector at the center of the array multiplied by a scaling factor, where the scaling factor is dependent on a distance of the metal reflector from the center of the array.
