    摘要: A laser medium comprises a solid-state host material and dopant species provided within the solid-state host material. A first portion of the dopant species has a first valence state, and a second portion of the dopant species has a second valence state. In an embodiment, a concentration of the first portion of the dopant species decreases radially with increasing distance from a center of the medium, and a concentration of the second portion of the dopant species increases radially with increasing distance from the center of the medium. The laser medium further comprises impurities within the solid-state host material, the impurities converting the first portion of the dopant species having the first valence state into the second portion of dopant species having the second valence state.

    摘要: When carrying workpieces from a loading area in which the workpieces are handled into a heat treatment furnace to make the workpieces subjected to a heat treatment process using a predetermined process gas, the loading area is evacuated and controlled at a predetermined low negative pressure. An exhaust for evacuating the loading area is connected to the loading area, and a controller controls the exhaust so that the loading area is maintained at the predetermined low negative pressure. A specific gas and particles contained in a gas discharged from the loading area are removed by filters.

    摘要: A temperature control system for a thermal reactor is disclosed that addresses many of the problems in the art. In accordance with one aspect of the disclosed control system, a plurality of temperature controllers are employed. Each temperature controller employs one or more dynamic models that are optimized for a given temperature range. The temperature range over which a particular controller is optimized is preferably generally exclusive of the temperature ranges over which other controllers of the plurality of temperature controllers are optimized. In accordance with another aspect of the control system the control system employs enhanced ramp trajectory logic. In accordance with another aspect of the control system, the control system employs a virtual temperature sensor in the event of a hardware failure of the corresponding non-virtual temperature sensor. Upon the detection of a failure of the non-virtual temperature sensor, the temperature control system automatically substitutes a virtual temperature sensor in its place as a control system input. In accordance with a still further aspect of the temperature control system, the control system is provided with control logic that switches the control mode of the system in the event of a failure of a heating element. All of the foregoing aspect of the present invention may be combined into a single temperature controller. Alternatively, these temperature control system improvements may be incorporated as individual elements, without reliance on the other inventive aspects disclosed herein.

    摘要: There is provided a heat-treating method and a radiant heating device by which an object to be heat-treated can be heat-treated at an actually desired temperature regardless of the dopant concentration or resistivity of the object at the time of heat-treating the object with a radiant heating device using a radiation thermometer as a temperature detector. In the method, the object is heat-treated at an actually desired temperature by correcting the temperature of the object in accordance with the dopant concentration or resistivity of the object. In the apparatus, the dopant concentration or resistivity of the object is inputted in advance to a temperature controller and the controller calculates an actual temperature of the object by correcting and computing the temperature of the object detected with the radiation thermometer in accordance with the dopant concentration or resistivity of the object and controls the temperature of the object based on the calculated temperature value.

    摘要: An apparatus for heat treating and quickly cooling substrates. The apparatus includes a cylindrical furnace core tube for containing substrates, a heater enclosing the furnace core tube, and outer cylinder enclosing and containing the furnace core tube and the heater, a blower for drafting cooling air to the space between the furnace core tube and the outer cylinder along the longitudinal direction of the furnace core tube, and a switching valve connected between the blower and both ends of the outer cylinder for switching the direction in which the cooling air travels. Since the direction of the cooling air is changed, the entire furnace core tube is uniformly cooled.

    摘要: An improved method for the heat treatment of quartz-glass tubes at temperatures above 1200.degree. C. is disclosed wherein a pressure is maintained within the glass tube which is 3 to 110 mm Hg higher than the pressure on the external surface of the quartz tube over the heated area of the tube for at least the length of time that a temperature of 1200.degree. C. is exceeded. The process is particularly useful for the treatment of quartz-glass tubes within which silicon wafers are disposed for the purpose of diffusing doping agent into silicon wafers or of depositing doped epitaxial layers on silicon wafers.

    摘要: The invention includes deposition apparatuses configured to monitor the temperature of a semiconductor wafer substrate by utilizing conduits which channel radiation from the substrate to a detector/signal processor system. In particular aspects, the temperature of the substrate can be measured while the substrate is spinning within a reaction chamber. The invention also includes deposition apparatuses in which flow of mixed gases is controlled by mass flow controllers provided downstream of the location where the gases are mixed and/or where flow of gases is measured with mass flow measurement devices provided downstream of the location where the gases are mixed. Additionally, the invention encompasses deposition apparatuses in which mass flow controllers and/or mass flow measurement devices are provided upstream of a header which splits a source gas into multiple paths directed toward multiple different reaction chambers.
