Classification: CPC G  H | IPC G  H

Claim 0:
1. An integrated circuit (IC), comprising:
a source region and a drain region in a semiconductor layer;
a channel region laterally between the source region and the drain region;
a sensing well on a back surface of the semiconductor layer and over the channel region, wherein a bottom surface of the sensing well is defined by the semiconductor layer;
an interconnect structure on a front surface of the semiconductor layer opposite the back surface of the semiconductor layer;
a biosensing film lining the sensing well and contacting the bottom surface of the sensing well;
a coating of selective binding agent over the biosensing film and configured to bind with a cardiac cell;
a plurality of first elongated heaters in the semiconductor layer; and
a plurality of fluid channel walls formed over the coating of the selective binding agent, 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 layer.
