摘要: Embodiments of the present invention generally relate to methods and apparatus for chemical vapor deposition (CVD) on a substrate, and, in particular, to a process chamber and components for use in metal organic chemical vapor deposition. The apparatus comprises a chamber body defining a process volume. A showerhead in a first plane defines a top portion of the process volume. A carrier plate extends across the process volume in a second plane forming an upper process volume between the showerhead and the susceptor plate. A transparent material in a third plane defines a bottom portion of the process volume forming a lower process volume between the carrier plate and the transparent material. A plurality of lamps forms one or more zones located below the transparent material. The apparatus provides uniform precursor flow and mixing while maintaining a uniform temperature over larger substrates thus yielding a corresponding increase in throughput.

摘要: A method and apparatus that may be utilized for chemical vapor deposition and/or hydride vapor phase epitaxial (HVPE) deposition are provided. In one embodiment, a metal organic chemical vapor deposition (MOCVD) process is used to deposit a Group III-nitride film on a plurality of substrates. A Group III precursor, such as trimethyl gallium, trimethyl aluminum or trimethyl indium and a nitrogen-containing precursor, such as ammonia, are delivered to a plurality of straight channels which isolate the precursor gases. The precursor gases are injected into mixing channels where the gases are mixed before entering a processing volume containing the substrates. Heat exchanging channels are provided for temperature control of the mixing channels to prevent undesirable condensation and reaction of the precursors.

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: A method and apparatus that may be utilized in deposition processes, such as hydride vapor phase epitaxial (HVPE) deposition of metal nitride films, are provided. A first set of passages may introduce a metal containing precursor gas. A second set of passages may provide a nitrogen-containing precursor gas. The first and second sets of passages may be interspersed in an effort to separate the metal containing precursor gas and nitrogen-containing precursor gas until they reach a substrate. An inert gas may also be flowed down through the passages to help keep separation and limit reaction at or near the passages, thereby preventing unwanted deposition on the passages.
