Abstract :
An efficient method for including quantum corrections in 3D ensemble Monte Carlo simulations based on the density gradient formalism is presented. The method is used to study the impact of transport on the current variations introduced by the random body thickness pattern in ultra thin body SOI MOSFETs. The resulting increased variability in drive current is studied in comparison between Monte Carlo and drift diffusion simulations
