Abstract
The present disclosure relates to an integrated chip having an integrated optical bio-sensor, and an associated method of fabrication. In some embodiments, the integrated optical bio-sensor has a sensing device arranged within a semiconductor substrate. An optical waveguide structure is located over a first side of the semiconductor substrate at a position over the sensing device. A dielectric structure is disposed onto the optical waveguide structure at a position that separates the optical waveguide structure from a sample retention area configured to receive a sample solution.
