Abstract :
A physics-based model is used to examine short-channel effects (SCEs) in undoped nanoscale independent-gate FinFETs, e.g., the MIGFET (L. Mathew, , Proc. IEEE Internat. SOI Conf., p. 187, 2004). Predicted current-voltage characteristics of MIGFETs in the single-gate mode show that the SCEs (threshold-voltage rolloff, subthreshold-swing degradation, and drain-induced barrier lowering) are actually less severe than those of the device in the double-gate mode. Insightful explanations of the results are given
