Original Abstract Submitted

In examples, an integrated circuit comprises a semiconductor die including a semiconductor substrate, a dielectric layer on the semiconductor substrate, and a metallization structure in the dielectric layer, in which the semiconductor substrate includes sensor circuitry coupled to the metallization structure, the dielectric layer having a sensing side facing away from the semiconductor substrate. The IC includes an insulation layer on the sensing side and a sensor terminal on the sensing side and coupled to the metallization structure. The IC device includes a restriction structure including an opening, in which the restriction structure encapsulates a fluid cavity on the sensing side and the sensor terminal is in the fluid cavity. The fluid cavity contains a functionalization material, configured to interact with a fluid in the fluid cavity to produce a signal detectable by the sensor circuitry via the sensor terminal.
