Abstract :
Degraded junction leakage current in scaled MOSFETs due to enhanced band-to-band tunneling (i.e. local Zener effect) is characterized based on a modified band-to-band tunneling model. To suppress the severe drain leakage current in the presence of high-dose halo implants, the impact of implant conditions on drain leakage current is estimated based on implant induced damage (point defect) profiles.
