Abstract
The random dopant fluctuation (RDF) in double-gate (DG) devices is investigated via physical analyses and numerical simulations. Our results show that extremely scaled devices, especially FinFETs with narrow device width (fin height) in each individual fin, are susceptible to RDF effects. Even in an undoped silicon channel, the existence of unwanted impurity dopant will still have a significant impact on device characteristics. Design implication from RDF is also discussed
