Abstract: Various embodiments of the present application are directed towards image sensors including composite backside illuminated (CBSI) structures to enhance performance. In some embodiments, a first trench isolation structure extends into a backside of a substrate to a first depth and comprises a pair of first trench isolation segments. A photodetector is in the substrate, between and bordering the first trench isolation segments. A second trench isolation structure is between the first trench isolation segments and extends into the backside of the substrate to a second depth less than the first depth. The second trench isolation structure comprises a pair of second trench isolation segments. An absorption enhancement structure overlies the photodetector, between the second trench isolation segments, and is recessed into the backside of the semiconductor substrate. The absorption enhancement structure and the second trench isolation structure collectively define a CBSI structure.

Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip. The method may be performed by forming a first conductive wire within a first dielectric structure formed on a first surface of a first substrate. A through-substrate-via (TSV) is formed to extend though the first substrate. A second conductive wire is formed within a second dielectric structure formed on a second surface of the first substrate opposing the first surface. The TSV electrically couples the first conductive wire and the second conductive wire. The first conductive wire, the second conductive wire, and the TSV define an inductor that wraps around an axis.
