    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.

    摘要: The present invention generally provides a method and apparatus for cleaning a showerhead of a deposition chamber, such as a metal organic chemical vapor deposition (MOCVD) chamber. In one embodiment, the showerhead is cleaned without exposing the chamber to the atmosphere outside of the chamber (i.e., in situ cleaning). In one embodiment, flow of liquid coolant through a cooling system that is in fluid communication with the showerhead is redirected to bypass the showerhead, and the liquid coolant is drained from the showerhead. In one embodiment, any remaining coolant is flushed from the showerhead via a pressurized gas source. In one embodiment, the showerhead is then heated to an appropriate cleaning temperature. In one embodiment, the flow of liquid coolant from the cooling system is then redirected to the showerhead and the system is adjusted for continued processing. Thus, the entire showerhead cleaning process is performed with minimal change to the flow of coolant through the cooling system.

    摘要: One embodiment of a quantum well structure comprises an active region including active layers that comprise quantum wells and barrier layers wherein some or all of the active layers are p type doped. P type doping some or all of the active layers improves the quantum efficiency of III-V compound semiconductor light emitting diodes by locating the position of the P-N junction in the active region of the device thereby enabling the dominant radiative recombination to occur within the active region. In one embodiment, the quantum well structure is fabricated in a cluster tool having a hydride vapor phase epitaxial (HVPE) deposition chamber with a eutectic source alloy. In one embodiment, the indium gallium nitride (InGaN) layer and the magnesium doped gallium nitride (Mg—GaN) or magnesium doped aluminum gallium nitride (Mg—AlGaN) layer are grown in separate chambers by a cluster tool to avoid indium and magnesium cross contamination. Doping of group III-nitrides by hydride vapor phase epitaxy using group III-metal eutectics is also described. In one embodiment, a source is provided for HVPE deposition of a p-type or an n-type group III-nitride epitaxial film, the source including a liquid phase mechanical (eutectic) mixture with a group III species. In one embodiment, a method is provided for performing HVPE deposition of a p-type or an n-type group III-nitride epitaxial film, the method including using a liquid phase mechanical (eutectic) mixture with a group III species.

    摘要: One embodiment of fabricating a p-down light emitting diode (LED) structure comprises depositing a high crystal quality p type contact layer, depositing an active region on top of the p type contact layer, and depositing an n type contact layer on top of the active region using a hydride vapor phase epitaxy (HVPE) process. The high crystal quality p type contact layer is deposited at high temperature to ensure the high crystal quality of the p type film. The n type contact layer is formed on top of the active region in a HVPE chamber at a low temperature to prevent thermal damage to the quantum wells in the active region below the n type contact layer. The processing chamber used to form the p type contact layer is a separate processing chamber than the processing chamber used to form the n type contact layer.

    摘要: One embodiment of depositing a gallium nitride (GaN) film on a substrate comprises providing a source of indium (In) and gallium (Ga) and depositing a monolayer of indium (In) on the surface of the gallium nitride (GaN) film. The monolayer of indium (In) acts as a surfactant to modify the surface energy and facilitate the epitaxial growth of the film by suppressing three dimensional growth and enhancing or facilitating two dimensional growth. The deposition temperature is kept sufficiently high to enable the indium (In) to undergo absorption and desorption on the gallium nitride (GaN) film without being incorporated into the solid phase gallium nitride (GaN) film. The gallium (Ga) and indium (In) can be provided by a single source or separate sources.
