Title
Germanium N and P Multifin Field-Effect Transistors With High-Performance Germanium (Ge)
and  were formed by a mesa structure using these p<sup>+</sup>-Ge/n-Si and n<sup>+</sup>-Ge/p-Si heterojunctions. A high-κ/metal gate stack was employed. The body-tied Ge multifin FinFET with a fin width (<i>W</i><sub>Fin</sub>) of ~ 40 nm, and the channel length (L<sub>Channel</sub>) was 150 nm for p-FinFET and of 110 nm for n-FinFET, exhibiting a driving current of 174 μA/μm at <i>V</i><sub>G</sub>=-2 V and 102 μA/μm at <i>V</i><sub>G</sub>=2 V , respectively. This is the first experimental demonstration of a body-tied high mobility Ge channel multifin FinFET using a top-down approach.</div></div>
