Classification: CPC G  H | IPC G  H

Claim 11:
12. An integrated circuit (IC), comprising:
a semiconductor substrate having a source region and a drain region;
a sensing well on a back surface of the semiconductor substrate;
a biosensing film lining the sensing well and contacting the back surface of the semiconductor substrate;
a biological material coating layer over the biosensing film;
a first heater in the semiconductor substrate and laterally spaced from the source region and the drain region, the first heater vertically overlapping with the biological material coating layer; and
a plurality of fluid channel walls formed over the biological material coating layer, wherein one of the fluid channel walls forms a horizontal interface with the biological material coating layer, and an entirety of the horizontal interface vertically overlaps with the first heater in the semiconductor substrate.
