Abstract
An extension of the twodimensional device simulation of smallgeometry semiconductor devices is described. The EBIC response is determined by means of device simulation. An important improvement of the determination of lateral dopant distribution in VLSI structures is obtained by combining of simulation and measurement. For calculation of EBIC signal the generation of electrons and holes due to the electron radiation must be modelled. The entire system of semiconductor equations which consists of Poisson equation, transport equations and continuity equations including the electron beam induced generation rate is solved. The corresponding current (EBIC signal) caused by the separation of the generated electronhole pairs in regions of high electric field strength and the following drift and diffusion to the contacts can be calculated for any structural and electrical conditions. The results of the combination of simulation and EBIC measurement is shown for VLSI transistors.
