Abstract
An integrated imaging device supports front face illumination with one or more photosensitive regions formed in a substrate. A lower dielectric region is provided over the substrate, the lower dielectric region having an upper face. A metal optical filter having a metal pattern is provided on the upper face (or extending into the lower dielectric region from the upper face). An upper dielectric region is provided on top of the lower dielectric region and metal optical filter. The lower dielectric region is at least part of a pre-metal dielectric layer, and the upper dielectric region is at least part of a metallization layer.
