Abstract
Embodiments of the present invention provide a circuit and method to characterize the impact of bias temperature instability on semiconductor devices. The circuit comprises a transistor having a gate, drain, source, and body terminal. Two AC pad sets each having a plurality of conductive pads. Two DC pads are in communication with a DC supply and/or meter. The gate terminal is in communication with a first conductive pad included in the plurality of conductive pads of each of the AC pad sets. The drain terminal is in communication with a second conductive pad of an AC pad set and the source terminal with a second conductive pad of another AC pad set. One DC pad is in communication with the gate terminal through a first serial resistor and another DC pad with the body terminal through a second serial resistor and provides an open-circuit for the gate and body terminals.
