Abstract

This invention relates to a novel inverted diffuser stagnation point flow reactor which can be used for vapor deposition of thin solid films on substrates. A metalorganic chemical vapor deposition reactor comprising a gas mixing chamber with gas entry ports into the mixing chamber; a substrate for deposition thereon of solid film; and a gas outlet for conveying gas away from the substrate, characterized by a capillary plug positioned at the base of an inverted diffuser between the mixing chamber and the substrate, the capillary plug serving to streamline the flow of gas to the substrate.
