This work reports for the first time a new Positive Bias Temperature Instability (PBTI) degradation mode in n-channel MOSFETs related to the introduction of plasma nitridation process step. The degradation is explained only by interface traps creation, differently to NBTI on p-channel MOSFETs where hole trapping might be dominant.
