Abstract

Non-equilibrium Green’s functions (NEGF) simulations are carried out to determine the impact of an unintentional dopant in the middle of the channel of a FinFET. We consider two different geometries scaled according to the ITRS and two different types of dopants, donors and acceptors. We show that there is a degradation of the subthreshold characteristics with the scaling of the smooth device and also a stronger impact of the stray dopants in the middle of the channel, with variations up to 32% in the current in on-state conditions.
