Abstract
An image sensor includes a substrate having photosensitive areas; an insulator spanning the substrate; and a first and second layer of a multi-layer metallization structure, wherein the first layer forms light shield regions over selected portions of the photosensitive area as well forming circuit interconnections and barrier regions to prevent spiking into the substrate or gates at contacts in the non-imaging area; and the second layer spanning the interconnections and barrier regions of the first layer only over the non-imaging areas and the second layer overlays edges of the first layer.
