Abstract
Various embodiments of the present disclosure are directed towards an integrated chip having a first image sensor element including a first doped region disposed within a substrate. The substrate comprises a first material and has a first surface opposite a second surface. A second image sensor element overlies the first image sensor element. The second image sensor element includes an active layer disposed in the substrate directly over the first doped region. The first doped region and the active layer are spaced vertically between the first and second surfaces of the substrate. The active layer comprises a second material different from the first material.
