    摘要: The present invention generally provides apparatus and methods for forming LED structures. In one embodiment where a sapphire substrate is selected, the growth of bulk Group III-nitrides may be deposited in a HVPE or MOCVD chamber while a separate processing chamber, such as a PVD, MOCVD, CVD, or ALD chamber, may be used to grow buffer layers on the sapphire substrate at lower growth rate. The buffer layer may be GaN, AlN, AlGaN, InGaN, or InAlGaN. In another embodiment where a silicon-based substrate is selected, the growth of bulk Group III-nitrides may be deposited in a HVPE or MOCVD chamber in which an Al-free environment is provided while a separate processing chamber with a Ga-free environment is used to grow a Ga-free buffer layer, such as Al, AlN, or SiN, on the silicon-based substrate. The separate processing chamber may be a PVD, CVD, MOCVD, a plasma assisted MOCVD, or other vapor phase deposition techniques.

    摘要: A method and apparatus for removing deposition products from internal surfaces of a processing chamber, and for preventing or slowing growth of such deposition products. A halogen containing gas is provided to the chamber to etch away deposition products. A halogen scavenging gas is provided to the chamber to remove any residual halogen. The halogen scavenging gas is generally activated by exposure to electromagnetic energy, either inside the processing chamber by thermal energy, or in a remote chamber by electric field, UV, or microwave. A deposition precursor may be added to the halogen scavenging gas to form a deposition resistant film on the internal surfaces of the chamber. Additionally, or alternately, a deposition resistant film may be formed by sputtering a deposition resistant metal onto internal components of the processing chamber in a PVD process.

    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: Highly ordered and aligned epitaxy of III-Nitride nanowires is demonstrated in this work. M-axis is identified as a preferential nanowire growth direction through a detailed study of GaN/AlN trunk/branch nanostructures by transmission electron microscopy. Crystallographic selectivity can be used to achieve spatial and orientational control of nanowire growth. Vertically aligned (Al)GaN nanowires are prepared on M-plane AlN substrates. Horizontally ordered nanowires, extending from the M-plane sidewalls of GaN hexagonal mesas or islands demonstrate new opportunities for self-aligned nanowire devices, interconnects, and networks.

    摘要: IMS gateway systems and methods are disclosed for providing budget control in an IMS network. IMS networks allow for media changes (e.g., audio to audio/video) during an IMS session. An IMS gateway system described herein receives a session control message (e.g., SIP INVITE message) responsive to the media change during the session. The IMS gateway system identifies media information for the new media in the session control message. The IMS gateway system generates a corresponding charging request message, and includes media information for the new media in the charging request message. The IMS gateway system then transmits the charging request message to an online charging system (OCS) to provide for charging of the session based on the new media for the session.
