Abstract :
This work shows that the recovery of NBTI degradation in ultra-small gate area pMOSFETs presents abrupt steps which are related to the detrapping of one hole. These results can be obtained by using a new approach to monitor the recovery, which is extremely more sensitive than previously proposed methodology. This result opens the way to model the NBTI degradation for ultra-small gate area devices which are main components of SRAM cells.
