WebThe extracted work functions of fully NiSi and NiGe gates from thickness-dependent flat band voltage were 4.55 and 5.2 eV respectively, which may provide possible wide work function tuning using NiSi/sub t-x/Ge/sub x/. WebJun 4, 1998 · Self-aligned silicidation is a well-known process to reduce source, drain, and gate resistances of submicron metal-oxide-semiconductor devices. This process is particularly useful for devices built on very thin Si layers (∼1000 Å or less) on insulators because of the large source and drain resistances associated with the thin Si layer.NiSi is …
