A review is given on actual numerical models for CVD equipment and processes. While the basic work concerning the differential equations and the boundary conditions has been established already a decade or more ago, the more recent availability of increased computing power has enabled simulation to become a predictive tool in equipment and process design. The present task in CVD simulation includes the stabilization of the numerical codes to achieve fast turnaround time and the improvement of transport and chemical models to proceed from qualitative studies to quantitative predictions. We will discuss models for heat and mass transport in low density gas mixtures and for homogeneous and heterogeneous reactions for a number of relevant CVD processes. Actual applications to problems in a submicron manufacturing environment will illustrate the presentation.
