Zusammenfassung:The present disclosure relates to an integrated chip including a semiconductor layer and a photodetector disposed along the semiconductor layer. A color filter is over the photodetector. A micro-lens is over the color filter. A dielectric structure comprising one or more dielectric layers is over the micro-lens. A receptor layer is over the dielectric structure. An optical signal enhancement structure is disposed along the dielectric structure and between the receptor layer and the micro-lens.
