PDF NEGATIVE BIAS TEMPERATURE INSTABILITY

So, energy higher than this enhances the NBTI and this enhanced NBTI leads to more Si-H bond breakdowns. Fig. 1.4 shows the variation of average hole energy with the S/D bias i.e. V ds. Fig 1.4: Average Energy vs S/D bias The main contribution to the V th shift is the energetic hole which induces higher NBTI degradation with higher S/D bias. 2.

5. NBTI Reliability Analysis

5. NBTI Reliability Analysis While most of the miniaturization problems in CMOS technology are more or less related to doping issues, the continued reduction of the gate oxide thickness has necessitated the incorporation of nitrogen into silicon dioxide, which in turn has aggravated NBTI negative bias temperature instability , especially, since we have entered the 90nm and 65nm technology nodes.
