Reliability-Conscious MOSFET Compact Modeling with Focus on the Defect-Screening Effect of Hot-Carrier Injection

Accurate prediction of device aging plays a vital role in the circuit design of advanced-node CMOS technologies. In particular, hot-carrier induced aging is so complicated that its modeling is often significantly simplified, with focus limited to digital circuits. We present here a novel reliability-aware compact modeling method that can accurately capture the full post-stress I-V characteristics of the MOSFET, taking into account the impact of drain depletion region on induced defects.
