摘要： Controlling crystal growth in a crystal growing system is described. The crystal growing system includes a heated crucible including a semiconductor melt from which a monocrystalline ingot is grown according to a Czochralski and the ingot is grown on a seed crystal pulled from the melt. The method includes applying a cusped magnetic field to the melt by supplying an upper coil with a first direct current (IUDC) and supplying a lower coil with a second direct current (ILDC). The method also includes supplying the upper coil with a first alternating current (IUAC) and supplying the lower coil with a second alternating current (ILAC) to generate a time-varying magnetic field, wherein the time-varying magnetic field generates a pumping force in the semiconductor melt.

摘要： A method for automatically attempting to recover equipment from a transient fault includes detecting a fault associated with the equipment in a node in a communications network, determining whether the fault associated with the equipment is transient, if the fault is transient automatically attempting to recover the equipment from the transient fault without user intervention, if the recovery attempt is successful monitoring the equipment for a pre-determined period of time to determine if the fault recurs, and if the fault recurs automatically re-attempting to recover the equipment from the fault until the fault does not recur in the pre-determined period of time or until a pre-determined number of attempts to recover the equipment have been performed.

摘要： The present invention provides a methods and system for producing semiconductor grade single crystals that are substantially free of undesirable agglomerated defects. A vacancy/interstial (V/I) boundary simulator analyzes various melt-solid interface shapes to predict a corresponding V/I transition curve for each of the various melt-solid interface shapes. A target melt-solid interface shape corresponding to a substantially flat V/I curve is identified for each of a plurality of axial positions along the length of the crystal. Target operating parameters to achieve each of the identified melt-solid interface shapes are stored in a melt-solid interfaced shape profile. A control system is responsive to the stored profile to generate one or more control signals to control one or more output devices such that the melt-solid interfaced shape substantially follows the target shapes as defined by the profile during crystal growth.

摘要： Methods and apparatus for establishing communication between a Mobile Node and a Home Agent are disclosed. The Home Agent receives a registration request packet from the Mobile Node, the registration request packet including an IP source address and a Home Agent address. The Home Agent then detects from the registration request packet when network address translation has been performed. When it has been detected that network address translation has been performed, a tunnel is set up between the Home Agent address and the IP source address.

摘要： A process for imparting controlled oxygen precipitation behavior to a single crystal silicon wafer. Specifically, prior to formation of the oxygen precipitates, the wafer bulk comprises dopant stabilized oxygen precipitate nucleation centers. The dopant is selected from a group consisting of nitrogen and carbon, and the concentration of the dopant is sufficient to allow the oxygen precipitate nucleation centers to withstand thermal processing, such as an epitaxial deposition process, while maintaining the ability to dissolve any grown-in nucleation centers.

摘要： A silicon wafer having a controlled oxygen precipitation behavior such that a denuded zone extending inward from the front surface and oxygen precipitates in the wafer bulk sufficient for intrinsic gettering purposes are ultimately formed. Specifically, prior to formation of the oxygen precipitates, the wafer bulk comprises dopant stabilized oxygen precipitate nucleation centers. The dopant is selected from a group consisting of nitrogen and carbon and the concentration of the dopant is sufficient to allow the oxygen precipitate nucleation centers to withstand thermal processing such as an epitaxial deposition process while maintaining the ability to dissolve any grown-in nucleation centers.

摘要： A system and method for context driven centralized help is provided. A daemon application initiated on a workstation or mobile device is configured to intercept a help request received in connection with an active application when a pre-defined triggering event is invoked. The daemon application captures context corresponding to the current page or function in use with the active application and generates a corresponding information dataset pertaining to the captured context. The information dataset is transmitted to a remote site, configured to query a content database, to determine if help-related content has been previously associated with the captured context, wherein a positive determination of the existence of such an association results in the help-related content being retrieved and displayed on the workstation or mobile device.
