  • Patent number: 8748952
    Abstract: A system and method for image sensing is disclosed. An embodiment comprises a substrate with a pixel region, the substrate having a front side and a backside. A co-implant process is performed along the backside of the substrate opposing a photosensitive element positioned along the front side of the substrate.
