Abstract
An IC includes a source region and a drain region in a semiconductor layer. A channel region is between the source region and the drain region. A sensing well is on a back surface of the semiconductor layer and over the channel region. An interconnect structure is on a front surface of the semiconductor layer opposite the back surface of the semiconductor layer. A biosensing film lines the sensing well and contacts a bottom surface of the sensing well that is defined by the semiconductor layer. A coating of selective binding agent is over the biosensing film and configured to bind with a cardiac cell.
