Abstract: This paper shows high-pressure anneal (HPA) as a performance booster for Si-passivated strained Ge (sGe) p-channel FinFET and gate-all-around (GAA) devices Abstract: In this work, the low-frequency noise (LFN) characteristics of hafnium-zirconium oxide (HZO) ferroelectric field-effect transistors (FeFETs) with and without high-pressure forming gas annealing (HPA) treatment are investigated

HPA was proceeded after TFT fabrication as a post process to improve electrical performance and stability The origin of $1/ {f}$ noise in the FeFET without HPA is changed from carrier number fluctuation to Hooge's mobility fluctuation after wake-up due to the. Meanwhile, the stress-induced leakage current characteristics were only improved by the D 2-HPA process, indicating that D-passivation is more resistant to external electrical stress than H-passivation
Highpressure anneal for indium gallium arsenide transistors. Improved interface quality and hole mobility (~600 cm 2 /Vs) are obtained on FinFET after HPA at 450°C Meanwhile, the stress-induced leakage current characteristics were only improved by the D 2-HPA process, indicating that D-passivation is more resistant to external electrical stress than H-passivation
