  • Patent number: 6859616
    Abstract: A semiconductor wafer is held by support pins horizontally. A susceptor and a heating plate are moved upwardly so that the semiconductor wafer is transferred from the support pins to the susceptor. At this time, a gas layer is sandwiched between the upper surface of the susceptor and the lower surface of the semiconductor wafer to cause the semiconductor wafer to float over the upper surface of the susceptor for about seventy seconds immediately after the semiconductor wafer is mounted on the upper surface of the susceptor. Then, flash lamps are lit up to perform flash heating while the semiconductor wafer is floating over the upper surface of the susceptor. Even when flashlight irradiation causes rapid thermal expansion of the wafer surface, the semiconductor wafer does not suffer a great stress. This can prevent the semiconductor wafer from breaking.

  • Patent number: 6825615
    Abstract: A lamp for a heat treatment apparatus that provides a rapid temperature rise without using a reflector. The lamp has at least one electrode part to which an electric power is supplied. A light-emitting part, connected to the electrode part, seals a filament for emitting light. A high-reflectance film is formed on an outer surface of a first portion of the light-emitting part so as to reflect light emitted from the filament. Reflected light exits from the light-emitting part through a second portion not having a film formed thereon. Accordingly, directivity of light exiting from the second portion of the light-emitting part is improved.

  • Publication number: 20040234919
    Abstract: A method and apparatus are provided for curing powdered coatings on the face of porous wood products, such as medium density fibreboard (MDF), wherein a pair of inclined infrared catalytic heaters are used to apply heat directly onto the side edges of the board. In addition, catalytic heaters that are normally used to heat and cure the face surface of the board are moved father back to reduce their effectiveness and to limit out-gassing of entrapped air from the inner low density core of the board. This arrangement also allows the coating to cure at the side edges of the board at approximately the same rate as the face of the board, promoting a more uniform curing of the powder coating.

  • Patent number: 6818864
    Abstract: A reactor chamber is positioned between a top array of LED heat lamps and a bottom array of LED heat lamps. The LED heat lamps forming the top and bottom arrays are individually or controllable in groups such that power output along each array of LED heat lamps can dynamically differ. The LED lamps can be controlled in response to, for example, feedback from chamber sensors, a desired temperature profile, and a failed LED lamp. In this way, the methods and systems described herein can dynamically compensate for operational characteristics of the reactor chamber. In one configuration, the LED heat lamps are arranged in a rectangular pattern. In some configurations, the LED heat lamps are arranged in a circular or a concentric pattern.

  • Publication number: 20040206743
    Abstract: A lamp house stores twenty-seven flash lamps in such a state that a longitudinal direction of each of the twenty-seven flash lamps extends in a horizontal direction (Y-direction), and that the twenty-seven flash lamps are arranged in parallel to one another at equally spaced intervals in a horizontal direction (X-direction) perpendicular to the longitudinal direction. There is employed such a layout that a direction of substrate loading and unloading by a transport robot is perpendicular to the longitudinal direction of the flash lamps (the longitudinal direction of the lamp house). In this layout, the distance required for the transport robot to transfer a semiconductor wafer by slidingly moving a transport arm can be minimized to permit a compact transport robot, so that a thermal processing apparatus itself is compact and excellent in maintainability.

  • Patent number: 6803546
    Abstract: A thermal processing method is described in which a temperature response of a substrate may be controlled during a heat-up phase or a cool-down phase, or during both phases. This reduces the thermal budget of the substrate and improves the quality and performance of devices formed on the substrate. In particular, by controlling the rate of heat transfer between the substrate and a thermal reservoir (e.g., a water-cooled reflector plate assembly), the temperature response of the substrate may be controlled during the thermal process. The rate of heat transfer may be changed by changing the thermal conductivity between the substrate and the thermal reservoir, by changing the emissivity of a surface of the thermal reservoir, or by changing the distance between the substrate and the thermal reservoir.
