In summary, comparison of NBTI characteristics in Al/HfO2/Ge with nitrided and non-nitrided Ge surface at high temperatures (125° C) reveals that nitridation creates additional bulk traps even though shows initial improvements. We, therefore, noticed that nitrided Ge has higher ΔV FB shift and stress induced leakage current than nonnitrided samples. NBTI degradation of nitrided germanium surface is also consistent with literature regarding NBTI on nitrided Si devices. Optimization on nitrogen content and nitridation procedure may improve sensitivity to NBTI.
