Claim Text:
1. A semiconductor device, comprising: a substrate including: a grid disposed on a back side illuminating film over the substrate, the grid comprising a conductive material, the grid having walls projecting outwardly from a topmost surface of the back side illuminating film to define a cavity, the cavity vertically aligned with the pixel region, wherein the back side illuminating film comprises a plasma enhanced oxide layer over an anti-reflective coating; a shield disposed on the back side illuminating film, the shield being vertically aligned with the BLC region, the shield comprising the conductive material; and a color filter disposed in the cavity between the walls of the grid, a topmost surface of the color filter being substantially coplanar with a topmost surface of the conductive material, a sidewall of the color filter contacting a sidewall of the shield, wherein a material of the color filter does not extend over and vertically aligned with the bonding-pad region of the substrate.
