  • Patent number: 9171746
    Abstract: A heater assembly with enhanced cooling pursuant to various embodiments described herein makes use of fluidic flow in the insulation or in the space used for insulation. By creating a natural convection or forced convection flow, the heater cools down faster, it can operate at lower temperatures and/or higher temperature precision, and it can improve temperature controllability by generating higher heat loss rates.

  • Patent number: 9114479
    Abstract: A method and apparatus are provided for treating a substrate. The substrate is positioned on a support in a thermal treatment chamber. Electromagnetic radiation is directed toward the substrate to anneal a portion of the substrate. Other electromagnetic radiation is directed toward the substrate to preheat a portion of the substrate. The preheating reduces thermal stresses at the boundary between the preheat region and the anneal region. Any number of anneal and preheat regions are contemplated, with varying shapes and temperature profiles, as needed for specific embodiments. Any convenient source of electromagnetic radiation may be used, such as lasers, heat lamps, white light lamps, or flash lamps.

  • Patent number: 9082728
    Abstract: A first flash heating is performed in which a flash lamp emits a first flashing light to a semiconductor wafer having been heated to a first preheating temperature equal to or lower than 650 degrees C. by a light emission from a halogen lamp so that the temperature of a surface of the semiconductor wafer reaches 1000 degrees C. or higher. Then, a second flash heating is performed in which a second flashing light is emitted to the semiconductor wafer having been further heated by a light emission of the halogen lamp. Performing the first flash heating can suppress diffusion of impurity in the subsequent second flash heating. In the second flash heating, the impurity is activated and introduced crystal defects are recovered.

  • Patent number: 8658945
    Abstract: A apparatus and method of thermally treating a wafer or other substrate, such as rapid thermal processing (RTP). An array of radiant lamps directs radiation to the back side of a wafer to heat the wafer. The front side of the wafer on which the patterned integrated circuits are being formed faces a radiant reflector. The wafer is thermally monitored for temperature and reflectivity from the side of the reflector. When the lamps are above the wafer, an edge ring supports the wafer in its edge exclusion zone. Alternatively, a reactor includes upwardly directed lamps and a reflector above and facing the front side of the wafer.

  • Patent number: 8624165
    Abstract: When a semiconductor wafer is preheated by halogen lamps, the temperature of a peripheral portion of the semiconductor wafer is lower than that of a central portion thereof. A laser light emitting part disposed immediately under the center of the semiconductor wafer is rotated about the center line of the semiconductor wafer, while laser light is directed from the laser light emitting part toward the peripheral portion of the semiconductor wafer. Thus, the irradiation spot of the laser light exiting the laser light emitting part swirls around along the peripheral portion of the back surface of the semiconductor wafer so as to draw a circular trajectory. As a result, the entire peripheral portion of the semiconductor wafer at a relatively low temperature is uniformly heated. This achieves a uniform in-plane temperature distribution of the semiconductor wafer.
