Abstract :
The Fowler-Nordheim (FN) stress on PMOSFET cause Idsat decrease and Vth increase. In this work, we have investigated FN stress induced device degradation mechanisms in PMOSFETs with different gate length and oxide thickness. We describe a quantitative relationship between Idsat, Idlin and Vth change under FN stress condition.
