摘要
A phenomenological model is proposed to describe the chemistry in CVD. The model takes account of the typical characteristics of CVD and is based on irreversible gas-surface reactions. To show its possibilities the model is used to derive rate coefficients from the observed kinetics of titanium nitride and tungsten deposition. It might become a simple and efficient tool to design deposition reactions for novel coatings.
