Abstract
An integrated chip including includes a substrate having a first side and a second side opposite the first side. The integrated chip further includes a first photodetector positioned in a first pixel region within the substrate. A floating diffusion region with a first doping concentration of a first polarity is positioned on the first side of the substrate in the first pixel region. A first body contact region with a second doping concentration of a second polarity different from the first polarity is positioned on the second side of the substrate in the first pixel region.
