Abstract:A novel anisotropic grid adaptation procedure for the stationary 2D drift-diffusion model in semiconductor device simulation is presented. The adaptation approach is based on the principle of equidistributing local dissipation rate errors and suitable for the Scharfetter-Gummel box method discretization on quad-tree based boundary Delaunay grids. In analogy to standard a posteriori error estimation techniques new error indicators are proposed and a novel iterative recomputation procedure is developed for robust adaptive simulations.
