Claim 16:
17. An 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 coating of selective binding agent over the biosensing film;
a plurality of fluid channel walls over the coating of selective binding agent and defining a fluid containment region over the sensing well; and
a plurality of first elongated heaters in the semiconductor substrate, wherein one of the fluid channel walls forms a horizontal interface with the coating of the selective binding agent, and an entirety of the horizontal interface vertically overlaps with one of the plurality of first elongated heaters in the semiconductor substrate.
