    Abstract: A sensor array includes a semiconductor substrate, a first plurality of FET sensors and a second plurality of FET sensors. Each of the FET sensors includes a channel region between a source and a drain region in the semiconductor substrate and underlying a gate structure disposed on a first side of the channel region, and a dielectric layer disposed on a second side of the channel region opposite from the first side of the channel region. A first plurality of capture reagents is coupled to the dielectric layer over the channel region of the first plurality of FET sensors, and a second plurality of capture reagents is coupled to the dielectric layer over the channel region of the second plurality of FET sensors. The second plurality of capture reagents is different from the first plurality of capture reagents.

    Abstract: The present disclosure relates to an integrated chip structure. The integrated chip structure includes a dielectric stack disposed on a substrate. The integrated chip structure further includes one or more piezoelectric ultrasonic transducers (PMUTs) and one or more capacitive ultrasonic transducers (CMUTs). The one or more PMUTs include a piezoelectric stack disposed within the dielectric stack over one or more PMUT cavities. The one or more CMUTs include electrodes disposed within the dielectric stack and separated by one or more CMUT cavities. An isolation chamber is arranged within the dielectric stack laterally between the one or more PMUTs and the one or more CMUTs. The isolation chamber vertically extends past at least a part of both the one or more PMUTs and the one or more CMUTs.
