Abstract: This paper presents a physics based, computationally efficient compact modeling approach for 3D vertical gate-all-around junctionless nanowire transistor (JLNT) arrays designed for future high performance computational logic circuit. The model features an explicit continuous analytical form adapted for a 14 nm channel JLNT technology and has been validated against extensive characterization results on a wide range of JLNT geometry, depicting good accuracy. Finally, preliminary logic circuit simulations have been performed for benchmarking performances of transistor logic circuits, such as inverters and ring oscillators, designed using the developed model.
