Abstract
The disclosure provides an integrated circuit (IC) structure with a body contact to a well with multiple diode junctions. A first doped well is in a substrate. A transistor is on the first doped well. A trench isolation (TI) is adjacent a portion of the first doped well. A second doped well within the substrate has a bottom surface beneath a bottom surface of the first doped well. A sidewall of the TI horizontally abuts the second doped well. A first diode junction is between the second doped well and the first doped well. A second diode junction is between the second doped well and the substrate. A body contact is on the second doped well.
