This paper evaluates the electric current terms from the longitudinal gradient of the longitudinal electric field in Bipolar Field-Effect-Transistors(BiFETs) with a pure base and two MOS gates operating in the unipolar(electron) current mode.These nMOS-BiFETs,known as nMOS-FinFETs,usually have electrically short channels compared with their intrinsic Debye length of about 25μm at room temperatures.These longitudinal electric current terms are important short-channel current components,which have been neglected in the computation of the long-channel electrical characteristics.This paper shows that the long-channel electrical characteristics are substantially modified by the longitudinal electrical current terms when the physical channel length is less than 100 nm.
