Abstract— After more than 30 years of validation of Moore’s law, the CMOS technology has already entered the nanoscale (sub-100nm) regime and faces strong limitations. The nanowire transistor is one candidate which has the potential to overcome the problems caused by short channel effects in SOI MOSFETs and has gained signifi -cant attention from both device and circuit developers. In addition to the effective suppression of short channel effects due to the improved gate strength, the multi-gate NWFETs show excellent current drive and have the merit that they are compatible with conventional CMOS processes. To simulate these devices, accurate modeling and calculations based on quantum mechanics are necessary to assess their performance limits, since cross- sections of the multigate NWFETs are expected to be a few nanometers wide in their ultimate scaling. In this paper we have explored the use of ATLAS including the Bohm Quantum Potential (BQP) for simulating and studying the shortchannel behaviour of nanowire FETs.
