Atomic Layer Deposition of HfO2 Thin Films on Ultrathin SiO2 Formed by Remote Plasma Oxidation An ultrathin SiO2 layer was grown on a H-terminated Si substrate by using remote plasma oxidation. The subsequent HfO2 deposition on the ultrathin SiO2 was... S Kim,S Woo,H Kim,... - Journal-...
In an effort to improve performance on Si and SiGe devices, multilayered oxides (SiO2/Ta2O5, Ta2O5/ZrO2, ZrO2/HfO2, SiO2/ZrO2, etc.) have been studied with the goal of lowering EOT, reducing leakage current, increasing interfacial layer stability, suppressing dopant diffusion, and improving ...

On the contrary, at a given stress voltage, the threshold voltage degradation and stress-induced leakage current degradation in HfAlO samples are higher, indicating shorter device lifetime compared to the HfO2 samples of same EOT. In addition, the mechanism of charge trapping in the oxide as ...
In this study, the spatial and energetic distributions of electrons trapped within a SiO2/HfO2 dual layer gate stack (EOT = 1 nm) of fully processed high-k/metal gate nFETs were investigated by discharging-sweep mode amplitude charge pumping (DSACP). DSACP enables the separate energy ...
