The deposition of thin solid films in CVD processes is determined by hydrodynamics, the chemical kinetics of the process and transport phenomena (heat transfer, species diffusion) in the reactor. The electric field must also be taken into account in simulation of some type CVD reactors (PECVD and RPCVD reactors). The paper deals with the modelling of CVD process in electric field. The purpose of this study was to estimate influence of electric field on deposition rate.
