An alternative characterization method of PFET sub-threshold slope under NBTI stress

Abstract

The effects of negative bias temperature instability (NBTI) on the sub-threshold performance of a pFET have been investigated by means of experimental methods. Specifically, the sub-threshold slope under static and dynamic NBTI stress has been characterized for different NBTI stress conditions. In order to perform the characterization, a proposal based on an alternative measurement technique to obtain the sub-threshold slope is presented. Our first results indicate that similar sub-threshold slope is obtained in all stress conditions.
