Unibody gas plasma source technology

摘要

A unibody, monolithic, one-piece PBN plasma chamber for an MBE gas plasma source. The chamber has a cylindrical configuration with at least one effusion orifice and a gas inlet opening. The gas inlet opening is preferably communicatively connected to an elongated, tubular inlet member. The inlet member is preferably coupled to a liquid cooled gas source by an intermediary connection member which is preferably constructed of a refxactory metal. The chamber minimizes leakage and maximizes efficiency. A gas plasma source assembly and a method for making the chamber are also disclosed.
