    摘要: The plasma-assisted metal-organic chemical vapor deposition (MOCVD) fabrication of a p-type group III-nitride material is described. For example, a method of fabricating a p-type group III-nitride material includes generating a nitrogen-based plasma. A nitrogen-containing species from the nitrogen-based plasma is reacted with a group III precursor and a p-type dopant precursor in a metal-organic chemical vapor deposition (MOCVD) chamber. A group III-nitride layer including p-type dopants is then formed above a substrate.

    摘要: A method for in-situ cleaning of a deposition system is disclosed. The method includes providing a deposition system with portions of the deposition system deposited with at least a group III element or a compound of a group III element. Halogen containing fluid is introduced into the deposition system. The halogen containing fluid is permitted to react with the group III element to form a halide. The halide in solid state is converted to a gaseous state. The halide in gaseous state is purged out of the deposition system.

    摘要: Embodiments of the present invention generally relate to methods and apparatus for removing unwanted deposition build-up from one more interior surfaces of a substrate processing chamber after a substrate is processed in a chamber to form, for example, Group III-V materials by metal-organic chemical vapor deposition (MOCVD) deposition processes and/or hydride vapor phase epitaxial (HVPE) deposition processes. In one embodiment, a method for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber is provided. The method comprises depositing one or more Group III containing layers over a substrate disposed in the substrate processing chamber, transferring the substrate out of the substrate processing chamber, and pulsing a halogen containing gas into the substrate processing chamber to remove at least a portion of the unwanted deposition build-up from one or more interior surfaces of the substrate processing chamber.
