摘要：

We report experimental results of the N/PBTI (Negative/Positive Bias Temperature Instability) reliability of vertically stacked Gate-All-Around (GAA) silicon nanowire (NW) MOSFETs. We benchmark the lifetime of these novel devices against FinFETs with different widths and similar gate-stack. We do not only compare the average degradation, but also the time-dependent variability. At last, we predict the impact of the nanowire diameter on the reliability using TCAD simulations. Both the experimental results and the simulations indicate that BTI reliability is not negatively impacted down to a nanowire diameter of 6nm.
