Abstract
An array of pixels is formed using a substrate, where each pixel has a substrate having an incident side for receiving incident light, a photosensitive region formed in the substrate, and a reflector having a complex-shaped surface. The reflector is formed in a portion of the substrate that is opposed to the incident side such that light incident on the complex-shaped surface of the reflector is reflected towards the photosensitive region.
