A novel process to etch away the defective Ge near Ge/Si interface from epitaxial Ge grown on SOI achieves a nearly defect-free channel, good gate control triangular gate, and larger effective width. Electrostatic control of SS= 94 mV/dec (at 1V) can be further improved if superior gate stack than EOT= 5.5 nm and D<sub>it</sub>= 1×10<sup>12</sup> cm<sup>-2</sup>eV<sup>-1</sup> is used. The I<sub>on</sub> can be further enhanced if the line edge roughness (LER) can be reduced.

The gate-all-around silicon nanowire transistors (SNWTs) are taken as example, the analog/RF performance, such as cutoff frequency (fT), transconductance efficiency (gm/Id), intrinsic gain (gm/gds) and comprehensive figure of merit (FOM) are optimized by utilizing the proposed method. Through design optimization, higher fT of SNWTs can be obtained compared with planar FETs, which can approach the ITRS projection, manifesting the promising potential of SNWTs for high frequency circuit applications.

Although the length of the considered device structures does not exceed a few nanometers, dissipative scattering mechanisms such as electron-phonon and anharmonic phonon-phonon scattering still play an important role and should therefore be fully taken into account by the modeling approach.
