  • Publication number: 20200152466
    Abstract: A method of doping a substrate. The method may include providing a substrate in a process chamber. The substrate may include a semiconductor structure, and a dopant layer disposed on a surface of the semiconductor structure. The method may include maintaining the substrate at a first temperature for a first interval, the first temperature corresponding to a vaporization temperature of the dopant layer. The method may further include rapidly cooling the substrate to a second temperature, less than the first temperature, and heating the substrate from the second temperature to a third temperature, greater than the first temperature.

  • Publication number: 20180270143
    Abstract: Spectrum analysis (SA) capability is included in various communication devices within a communication network. One or more of the devices use the SA information from other devices in the system to determine status of various communication links were devices in the system. One or more processors within one or more devices can identify any actual/existing or expected failure or degradation of the various components within the system. Such components may include communication devices, communication channels or links, interfaces, interconnections, etc. When an actual/existing or expected failure or degradation is identified, the affected components may be serviced or devices within the system may operate to mitigate any reduction in performance caused by such problems. Such SA functionality/capability may be implemented in one communication device or in a distributed manner across a number of devices in a communication system.

  • Patent number: 8817865
    Abstract: Linear distortion and interference estimation using decision feedback equalizer coefficients. Processing of different respective groups of equalizer coefficients may be made to determine the residual frequency response of an equalizer and/or device in which the equalizer is implemented. Such an equalizer may be implemented within any of a number of respective communication devices including those operative within satellite, wireless, wired, fiber-optic, and/or mobile communication systems. A first group of equalizer coefficients corresponds to certain filtering characteristics of the equalizer and/or device in which the equalizer is implemented. The equalizer is implemented to process a signal to generate a second group of equalizer coefficients.

  • Patent number: 8724689
    Abstract: Narrowband ingress estimation and characterization using equalizer taps. A equalizer including a feed forward equalizer (FFE) and a decision feedback equalizer (DFE) is implemented to process an input signal thereby generating an output signal. Analysis of the frequency response of the equalizer including the FFE and the DFE of the equalizer allows for the determination of whether or not narrowband ingress exists within the signal received by the equalizer. For example, analysis of the signal output from the equalizer provides for determination of the overall frequency response of the equalizer. In addition, analysis of the respective equalizer coefficients within one or both of the FFE and the DFE of the equalizer may be used to determine the overall frequency response of the equalizer. Narrowband ingress may be identified when the combination of the FFE (having a notch therein) and the DFE provides for an overall flat frequency response.

  • Patent number: 8320088
    Abstract: An improved power transfer mechanism is disclosed, which is particularly beneficial in power transmission applications. The mechanism allows the SCFCL system to have more than one electrical reference. The use of hydraulic power simplifies the design of systems in which one part of the system is referenced to ground, while a second part of the system is referenced to a different voltage, typically much higher than ground. For example, the tank of the SCFCL system may not be connected to ground, while hydraulic power supply is referenced to ground. This embodiment is performed without the use of an electrically conductive path between the two parts of the system.
