Abstract :
A bias-dependent QM correction for surface potential calculation is derived for DG MOSFETs. The QM-corrected surface potential agrees with the 2D simulation results well. This indicates that both Vth shift in the subthreshold and strong inversion regions and gate capacitance degradation in the strong inversion region due to QM are predicted simultaneously. The model can predict the complicated QM effect dependence on various device parameters, such as Nbody, Tsi, Tox, etc
