  • Patent number: 10879406
    Abstract: The present disclosure relates to an integrated chip that has a light sensing element arranged within a substrate. An absorption enhancement structure is arranged along a back-side of the substrate, and an interconnect structure is arranged along a front-side of the substrate. A reflection structure includes a dielectric structure and a plurality of semiconductor pillars that matingly engage the dielectric structure. The dielectric structure and semiconductor pillars are arranged along the front-side of the substrate and are spaced between the light sensing element and the interconnect structure. The plurality of semiconductor pillars and the dielectric structure are collectively configured to reflect incident light that has passed through the absorption enhancement structure and through the light sensing element back towards the light sensing element before the incident light strikes the interconnect structure.

  • Patent number: 10833115
    Abstract: In some embodiments, the present disclosure relates to an integrated chip having an inter-layer dielectric (ILD) structure along a first surface of a substrate having a photodetector. An etch stop layer is over the ILD structure, and a reflector is surrounded by the etch stop layer and the ILD structure. The reflector has a curved surface facing the substrate at a location directly over the photodetector. The curved surface is coupled between a first sidewall and a second sidewall of the reflector. The reflector has larger thicknesses along the first sidewall and the second sidewall than at a center of the reflector between the first sidewall and the second sidewall.
