  • PECVD PROCESS
    Publication number: 20160017497
    Abstract: A method of processing a substrate according to a PECVD process is described. Temperature profile of the substrate is adjusted to change deposition rate profile across the substrate. Plasma density profile is adjusted to change deposition rate profile across the substrate. Chamber surfaces exposed to the plasma are heated to improve plasma density uniformity and reduce formation of low quality deposits on chamber surfaces. In situ metrology may be used to monitor progress of a deposition process and trigger control actions involving substrate temperature profile, plasma density profile, pressure, temperature, and flow of reactants.

  • Mobile communication apparatus having anti-theft and auto-notification functions
    Patent number: 9241058
    Abstract: A mobile communication apparatus comprises an anti-theft control circuit and a transmission control circuit. The anti-theft control circuit has an information management module and a security module. The information management module is used for storing a user personal database comprising at least one of a phonebook database, a schedule database, and an e-mail database. The transmission control circuit is used for transmitting data and/or signals. When the transmission control circuit receives a remote message, the security module examines whether the remote message is a predetermined legitimate remote control message; wherein if YES, the transmission control circuit sends out at least one record of the phonebook database, the schedule database, and the e-mail database to an electronic apparatus indicated by the remote message.

  • Data communication with compensation for packet loss
    Patent number: 9237105
    Abstract: Described is a technology by which a relay is coupled (e.g., by a wire) to a network and (e.g., by a wireless link) to an endpoint. Incoming data packets directed towards the endpoint are processed by the relay according to an error correction scheme, such as one that replicates packets. The reprocessed packets, which in general are more robust against packet loss, are then sent to the endpoint. For outgoing data packets received from the endpoint, the relay reprocesses the outgoing packets based upon the error correction scheme, such as to remove redundant packets before transmitting them to the network over the wire. Also described are various error correction schemes, and various types of computing devices that may be used as relays. The relay may be built into the network infrastructure, and/or a directory service may be employed to automatically find a suitable relay node for an endpoint device.
