Abstract

The present invention provides a chemical vapor deposition using, as feed gases, a silicon compound and hydrazine or a derivative thereof, or a compound containing both silicon and nitrogen, and a process and a system useful for chemical vapor deposition growth, in which a chlorinated silane compound and ammonia, feed gases, are preliminarily reacted with each other, and the resulting reaction gas mixture from which the ammonium halide produced by the preliminary reaction has been eliminated is fed to form a thin film on a substrate.
