Abstract
An imager device having a recessed color filter array formed in a trench of a material layer above a pixel array. Light-sensitive pixels are formed in the center area of the array, while non-light-sensitive pixels are formed in a buffer region adjacent the light-sensitive pixels and beneath an area of the color filter array having a non-uniform thickness. The non-light-sensitive pixels may be anti-fuse pixels functioning as individual, programmable memory cells, thereby providing in-pixel memory for the imager device.
