  • 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: 7398693
    Abstract: The present invention generally relates to methods for the rapid thermal processing (RTP) of a substrate. Embodiments of the invention include controlling a thermal process using either a real-time adaptive control algorithm or by using a control algorithm that is selected from a suite of fixed control algorithms designed for a variety of substrate types. Selection of the control algorithm is based on optical properties of the substrate measured during the thermal process. In one embodiment, a combination of control algorithms are used, wherein the majority of lamp groupings are controlled with a fixed control algorithm and a substantially smaller number of lamp zones are controlled by an adaptive control algorithm.

  • Publication number: 20080090309
    Abstract: A method for rapid thermal annealing is disclosed. As the substrate is inserted into an annealing chamber, it begins to heat due to the heat radiating from chamber components that were heated when a previous substrate was annealed. Thus, the leading edge of the substrate may be at an elevated temperature while the trailing edge of the substrate may be at room temperature while the substrate is inserted causing a temperature gradient is present across the substrate. Once the substrate is completely inserted into the annealing chamber, the temperature gradient may still be present. By compensating for the temperature gradient across the substrate, the substrate may be annealed uniformly.

  • Publication number: 20070215049
    Abstract: Three wafer support fixtures transfer a wafer for thermal processing in an inverted orientation within a heating chamber. Two co-planar support fixtures grab the wafer edge inside the chamber from a blade within a 1.5 mm wafer exclusion zone and hold it above the edge ring during heat-up and then withdraw thermal processing. A third support fixture chucks the wafer backside and transfers it to sloping support areas of the edge ring. The three support fixtures inside the chamber are individually controlled from outside.
