Abstract

Various embodiments of the present disclosure are directed towards an integrated chip. The integrated chip includes a first photodetector disposed in a first pixel region of a semiconductor substrate and a second photodetector disposed in a second pixel region of the semiconductor substrate. The second photodetector is laterally separated from the first photodetector. A first diffuser is disposed along a back-side of the semiconductor substrate and over the first photodetector. A second diffuser is disposed along the back-side of the semiconductor substrate and over the second photodetector. A first midline of the first pixel region and a second midline of the second pixel region are both disposed laterally between the first diffuser and the second diffuser.
