A chemical vapor deposition process in which an internal reactor is disposed within a chemical vapor deposition reactor including means for enclosing a reaction chamber and means for heating the reaction chamber. The position at which the internal reactor is disposed relative to the heating means is selected to provide control of the temperature within the internal reactor. At least two solid precursor materials are placed in the internal reactor and are contacted with at least one precursor gas, reactive with the solid precursor materials to produce at least two reactant gases. These gases are directed to the reaction chamber to react with one or more additional reactants.

Internal reactor method for chemical vapor deposition

A CVD apparatus including an internal reactor for in-situ generation of source gases for the CVD reaction. The internal reactor comprises a shell for containing solid precursor material, inlet and outlet means for a precursor gas and the gaseous product respectively, and preferably gas distribution means and means for preventing entrainment of the solid precursor in the gas flow. The internal reactor is positioned within the CVD reactor to provide the optimum temperature for the reaction taking place within the internal reactor.
