    Abstract: A CMOS image sensor includes PDAF pixels distributed in an array of image pixels in plan view. Each PDAF pixel includes m×m binned photodiodes, a PDAF color filter overlying the binned photodiodes and laterally surrounded by a first isolation structure, and a PDAF micro-lens overlying the PDAF color filter. A first horizontal distance between a center of the PDAF color filter and a center of the binned photodiodes varies depending on a location of the PDAF pixel in plan view in the CMOS image sensor. Additionally, the first isolation structure includes a first low-n dielectric grid, a second low-n dielectric grid underlying the first low-n dielectric grid, and a metal grid enclosed by the second low-n dielectric grid.
