The scalability of the SiGe channel MOSFET to the 0.1 μm technology generation was studied using the two-dimensional device simulator MEDICI. For this purpose, devices with n+ and p+ polysilicon gates and with intermediate work function SiGe gates were considered. It was found that the SiGe channel pMOSFET offers no advantage for technology generation beyond 0.1 μm.
