Abstract

Schottky-barrier source/drain (S/D) Germanium p-channel MOSFETs are demonstrated for the first time with HfAIO gate dielectric, HfN-TaN metal gate and self-aligned NiGe S/D. The drain drivability is improved over the silicon counterpart with PtSi S/D by as much as ~5 times due to the lower hole Schottky barrier of the NiGe-Ge contact than that of PtSi—Si contact as well as the higher mobility of Ge channel than that of Si.
