  • Patent number: 7573829
    Abstract: A method and apparatus for testing network performance are provided. In data provided by an application on a first host for transport or communication to an application associated with a second host according to a first data transport protocol is intercepted at the first host and wrapped or encapsulated in a test data packet formatted according to a second data transport protocol. The test data packet formatted according to the second data transport protocol includes, in addition to data comprising all or a portion of the original data packet, instrumentation information. The test data packet is then delivered to the second host, which unpacks the original data packet and the instrumentation information. A response packet containing instrumentation information may be sent from the second host to the first host to provide roundtrip performance metrics.

  • Patent number: 7529558
    Abstract: A system and method are provided for establishing location-based push-to-talk communication groups. A location determining application is incorporated within a communication network for members of a push-to-talk group. This application may include global positioning satellite technology incorporated in mobile communication devices carried by the members, a triangulation application incorporated at a communications server, or an RFID application associated with the members. Location data obtained on the members is maintained in a database that is accessible to a communications server facilitating communication between the members. When a member initiates a push-to-talk communication, other members of the group are contacted based upon their locations. The communication can be selectively transmitted to either those within a pre-designated location, or outside of the pre-designated location.

  • Patent number: 7389489
    Abstract: Techniques are provided for converting a circuit design file so that it is compatible with a new programmable IC. Black box declarations and instances of black boxes in the circuit design file are located automatically. Then, information about the function and structure of the black boxes is gathered from various user files.

  • Publication number: 20080054228
    Abstract: Adding at least one non-silicon precursor (such as a germanium precursor, a carbon precursor, etc.) during formation of a silicon nitride, silicon oxide, silicon oxynitride or silicon carbide film improves the deposition rate and/or makes possible tuning of properties of the film, such as tuning of the stress of the film. Also, in a doped silicon oxide or doped silicon nitride or other doped structure, the presence of the dopant may be used for measuring a signal associated with the dopant, as an etch-stop or otherwise for achieving control during etching.

  • Publication number: 20080042166
    Abstract: A semiconductor structure for use as a template for forming high-performance metal oxide semiconductor field effect transistor (MOSFET) devices is provided. More specifically, the present invention provides a structure that includes a SiGe-on-insulator substrate including a tensile-strained SiGe alloy layer located atop an insulating layer; and a strained Si layer atop the tensile-strained SiGe alloy layer. The present invention also provides a method of forming the tensile-strained SGOI substrate as well as the heterostructure described above. The method of the present invention decouples the preference for high strain in the strained Si layer and the Ge content in the underlying layer by providing a tensile-strained SiGe alloy layer directly atop on an insulating layer.

  • Publication number: 20080013457
    Abstract: A programmable channel-swap crossbar switch for swapping signal flow from one channel to another within an Ethernet physical layer device (PHY) is presented. The crossbar switch includes two or more programmed multiplexers, each multiplexer configured to receive two or more input signals and to select which one of the input signals to pass to a programmed corresponding channel, such that a first input signal associated with a first channel can be swapped to a second channel as operating conditions necessitate. The crossbar switch can be used for Ethernet communications with various communication speeds, such as 10BaseT, 100BaseT, and Gigabit communications. A crossbar switch can be used in both a transmit path and a receive path. Two crossbar switches may be used in a receive path in order to undo channel swapping for control signal processing. A method of channel-swapping in an Ethernet PHY communications system is also presented.

  • Publication number: 20070293031
    Abstract: A multi-layered gate electrode stack structure of a field effect transistor device is formed on a silicon nano crystal seed layer on the gate dielectric. The small grain size of the silicon nano crystal layer allows for deposition of a uniform and continuous layer of poly-SiGe with a [Ge] of up to at least 70% using in situ rapid thermal chemical vapor deposition (RTCVD). An in-situ purge of the deposition chamber in a oxygen ambient at rapidly reduced temperatures results in a thin SiO2 or SixGeyOz interfacial layer of 3 to 4 A thick. The thin SiO2 or SixGeyOz interfacial layer is sufficiently thin and discontinuous to offer little resistance to gate current flow yet has sufficient [O] to effectively block upward Ge diffusion during heat treatment to thereby allow silicidation of the subsequently deposited layer of cobalt. The gate electrode stack structure is used for both nFETs and pFETs.

  • Publication number: 20070291784
    Abstract: A physical layer device (PLD) includes a first serializer-deserializer (SERDES) device and a second SERDES device. Each SERDES device includes an analog portion with a serial port that is configured to communicate serial data with various network devices, and a digital portion that is configured to communicate parallel data with other various network devices. The PLD includes a first signal path that is configured to route serial data signals between the analog portions of the SERDES devices, bypassing the digital portions of the SERDES devices. Therefore, the SERDES devices can directly communicate serial data without performing parallel data conversion. A second signal path is configured to route recovered clock and data signals between the analog portions of the SERDES devices, but still bypassing the digital portions of the SERDES devices. The recovered clock and data signals are then regenerated before being transmitted over a network device.

  • Publication number: 20070278517
    Abstract: The present invention provides semiconductor structures and a method of fabricating such structures for application of MOSFET devices. The semiconductor structures are fabricated in such a way so that the layer structure in the regions of the wafer where n-MOSFETs are fabricated is different from the layer structure in regions of the wafers where p-MOSFETs are fabricated. The structures are fabricated by first forming a damaged region with a surface of a Si-containing substrate by ion implanting of a light atom such as He. A strained SiGe alloy is then formed on the Si-containing substrate containing the damaged region. An annealing step is then employed to cause substantial relaxation of the strained SiGe alloy via a defect initiated strain relaxation. Next, a strained semiconductor cap such as strained Si is formed on the relaxed SiGe alloy.
