Abstract :
In this work, we investigate recovery characteristics post NBTI stress when the recovery bias remains negative but lower in magnitude than the stress bias, consolidating the viewpoint involving role of hole trapping during NBTI degradation. We show that successive negative recovery biases can be applied to view trapping and detrapping behavior explicitly
