Abstract :
In this paper we summarize the basics of the conformal mapping technique and demonstrate its usefulness to two-dimensional bulk MOS transistor modeling. Furthermore we present an analytical technique, which allows to apply the 2D conformal mapping technique to the 3D potential problem in a triple-gate device. Herewith model equations for potential barrier, subthreshold slope and threshold voltage in FinFETs have been derived.
