Abstract:
A single photon avalanche diode (SPAD) image sensor is disclosed. The SPAD image sensor include: a substrate of a first conductivity type, the substrate having a front surface and a back surface; a deep trench isolation (DTI) extending from the front surface toward the back surface of the substrate, the DTI having a first surface and a second surface opposite to the first surface, the first surface being level with the front surface of the substrate; an epitaxial layer of a second conductivity type opposite to the first conductivity type, the epitaxial layer surrounding sidewalls and the second surface of the DTI; and an implant region of the first conductivity type extending from the front surface to the back surface of the substrate. An associated method for fabricating the SPAD image sensor is also disclosed.

Claim (Index 19):
The SPAD image sensor of  claim 18 , wherein a center of the lens overlaps a center of the DTI from a top view.
