    摘要: A method of forming a sheet wafer melts feedstock material in a crucible that is part of a crystal growth furnace, and passes a plurality of filaments through the crucible to form a (un-separated) sheet wafers. A plurality of sheet wafers may be formed in different lanes in the crucible. One or more vision systems is used, during growth, to determine if a sheet wafer has a defective condition. If a defect is detected, then any of a variety of corrective actions may be taken, such as activating a cutting device to remove at least a portion of the sheet wafer, assessing the defect and grading a portion of the sheet wafer (e.g., for sorting based on grade), and/or producing an indicia. In a multiple-lane embodiment, a defect may be attended to in one lane while sheet growth continues in one or more other lanes.

    摘要: A leak detection system includes a trace gas leak detector having a wireless base unit, and a handheld wireless remote unit to generate an alphanumeric display of leak rate measured by the leak detector, in response to leak detector information received by wireless link from the leak detector. The remote unit may include a wireless transceiver to communicate with the wireless base unit of the leak detector, a display unit and a controller, responsive to the received leak detector information, to generate the display on the display unit. The remote unit may be configured to control the leak detector and may be configured to display a leak detector operating mode.

    摘要: A method and apparatus for forming a sheet wafer melts feedstock material in a crucible that is part of a crystal growth furnace, passes a plurality of filaments through the crucible to form a sheet wafer, and cuts a portion of the sheet wafer to form a smaller sheet wafer. The method and apparatus then determine the weight of the smaller sheet wafer, and control the temperature of the melted feedstock material (e.g., by controlling crucible temperature or by interfacing with another temperature control system) as a function of the determined weight.

    摘要: A method of forming a sheet wafer 1) passes at least two filaments through a molten material to produce a partially formed sheet wafer, 2) directs a cooling fluid at a flow rate toward the partially formed sheet wafer to convectively cool a given portion of the partially formed sheet wafer, and 3) monitors the thickness of the given portion of the partially formed sheet wafer. To ensure appropriate thicknesses of the wafer, the method controls the flow rate of the cooling fluid as a function of the thickness of the given portion of the partially formed sheet wafer.
