Abstract
Various embodiments of the present disclosure are directed towards an integrated chip including a substrate comprising a first semiconductor material and a recess in a top surface of the substrate. An absorption structure is disposed within the recess and comprising a second semiconductor material different from the first semiconductor material. The absorption structure has a first doping type. A vertical well region is disposed within the substrate and underlies the absorption structure. The vertical well region has a second doping type different from the first doping type. A liner layer is disposed between the absorption structure and the substrate. The liner layer comprises the second semiconductor material and separates the vertical well region from the absorption structure.
