摘要:
Methods, systems, and techniques for dual-mode communication are provided. Example embodiments provide an enhanced mobile device that includes a low latency transceiver and a high latency transceiver. In some cases, the enhanced mobile device is operated by a customer and configured to interact with a point of service computing system via both the low and high latency transceivers to facilitate a customer interaction at a point of service location. For example, the enhanced mobile device may transmit via its high latency transceiver an indication that it is en route to the point of service location. Upon arrival at the point of service location, the enhanced mobile device may transmit via its low latency transceiver an indication that the customer has arrived at the point of service location. The point of service computing system may then provide a service based on the information received from the enhanced mobile device.

A modular plasma source assembly for use with a processing chamber is described. The assembly includes an RF hot electrode with an end dielectric and a sliding ground connection positioned adjacent the sides of the electrode. A seal foil connects the sliding ground connection to the housing to provide a grounded sliding ground connection separated from the hot electrode by the end dielectric. A coaxial feed line passes through a conduit into the RF hot electrode isolated from the processing environment so that the coaxial RF feed line is at atmospheric pressure while the plasma processing region is at reduced pressure.

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.

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.

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:
Described are apparatus and methods for processing a semiconductor wafer in which the gap between the wafer surface and the gas distribution assembly remains uniform and of known thickness. The wafer is positioned within a susceptor assembly and the assembly is lifted toward the gas distribution assembly using actuators. The wafer can be lifted toward the gas distribution assembly by creating a fluid bearing below and/or above the wafer.
