    摘要: A method and apparatus for hydride vapor phase epitaxial (HVPE) deposition is disclosed. In the HVPE process, a hydride gas flows over a metal source to react with the metal source, which then reacts at the surface of a substrate to deposit a metal nitride layer. The metal source comprises gallium, aluminum, and/or indium. The hydride gas is evenly provided over the metal source to increase efficiency of hydride-metal source reaction. An exhaust positioned diametrically across the chamber from the metal source creates a cross flow of the hydride-metal source product and nitrogen precursor across the chamber tangential to the substrate. A purge gas flowing perpendicular to the cross flow directs the hydride-metal source product and nitrogen precursor to remain as close to the substrate as possible.

    摘要: Embodiments of the invention provide an apparatus and a method for generating a gaseous chemical precursor that may be used in a vapor deposition processing system. In one embodiment, the apparatus contains a valve manifold assembly, which includes a valve assembly body having at least one embedded electric heater, an inlet channel passing through the valve assembly body, a first pneumatic valve and a first manual valve coupled to the valve assembly body and positioned to control fluid flow within the inlet channel, an outlet channel passing through the valve assembly body, and a second pneumatic valve and a second manual valve coupled to the valve assembly body and positioned to control fluid flow within the outlet channel. The valve manifold assembly further contains a bypass channel connected to and between the inlet and outlet channels, and containing a bypass valve positioned to control fluid flow within the bypass channel.
