TL;DR: A method is described for terminating mesh lines in one or two dimensions within the context of the finite difference formulation of the semiconductor device equations that can result in a system of equations that are better conditioned in the case of devices where the coupling between portions of the device is poor in the numerical sense.
Abstract: In this paper a method is described for terminating mesh lines in one or two dimensions within the context of the finite difference formulation of the semiconductor device equations This saves both computer time and storage since unneeded mesh points are eliminated. However, more importantly it can result in a system of equations that are better conditioned in the case of devices where the coupling between portions of the device is poor in the numerical sense. Several examples are shown of field effect power devices where convergence was only possible after the line termination methods were applied. Finally, a short discussion is presented on the relative advantages of the finite difference formalism in comparison to the finite element methods in light of the line termination technique.
