6.1 Modeling of Low-Pressure Processes

In the following the model for low-pressure processes will be derived in a general way applicable to etching as well as to deposition processes. Starting point for the considerations are the transport kinetics of particles in low-pressure atmospheres, which are completed with the discussion about particle distributions. Finally the derivations lead to the general formulation of the rate equations.
