Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 6:
7. An integrated chip, comprising:
a first photodetector disposed in a semiconductor substrate;
a second photodetector disposed in the semiconductor substrate, wherein the second photodetector is laterally separated from the first photodetector;
a first diffuser disposed along a back-side of the semiconductor substrate and over the first photodetector, the first diffuser being laterally offset from a lateral center of the first photodetector in a first direction; and
a second diffuser disposed along the back-side of the semiconductor substrate and over the second photodetector, the second diffuser being laterally offset from a lateral center of the second photodetector in a second direction opposite the first direction.
