    Abstract: The present invention relates to a thermal processing method wherein a cylindrical process tube that has at one end an entrance/exit is provided at the other end thereof with a heat source, and thermal processing is performed on a workpiece which has been brought in from the entrance/exit of the process tube to a prescribed position therein. This thermal processing method and an apparatus therefor is characterized in that, when the workpiece is moved to the prescribed position, it is first moved to a proximity position that is closer to the heat source than the prescribed position, then it is returned therefrom to the prescribed position. The invention is further characterized in that, if the actual processing temperature at the prescribed position changes while the workpiece is undergoing thermal processing, the workpiece is moved such that the position of the workpiece with respect to the heat generation source is changed in order to return the processing temperature at the prescribed position, to the prescribed processing temperature. This ensures that the temperature of the workpiece can be rapidly raised to the prescribed processing temperature and also that, if the temperature of the workpiece should change, it can be rapidly returned to the prescribed processing temperature.

    Abstract: In a processing chamber that includes a wafer pedestal adapted to heat and cool a wafer during wafer processing, where the wafer is secured to the pedestal with a wafer clamp ring, a yoke having a surface in spaced facing relation with a wafer surface is positioned atop the clamp ring proximate to the wafer. The yoke surface includes a concave circumferential portion that is curved to provide a reflector, for example a parabolic or elliptical reflector, that is positioned having a focal point coincident with the wafer edge. Reflector positioning and spacing relative to the wafer surface encourage reflection of heat radiated from the edge portion of the wafer surface back to the wafer edge to mitigate thermal losses at the wafer edge and improve temperature uniformity across the surface of the wafer.

    Abstract: A three zone rapid thermal processing system includes three arrays of radiant heating lamps for heating a semiconductor wafer. The arrays are positioned along the axis of the wafer such that one array is adjacent one face of the wafer, the second array is adjacent the second face of the wafer and the third array is adjacent the edge of the wafer. A wafer holder holds the wafer face transverse to the common axis of the radiant heating lamps. Reflectors at each array reflect radiant heat onto the wafer. The arrays are independently connected to power sources and a controller to provide efficient coupling of the heat sources and a uniform temperature distribution across a wafer.

    Abstract: A conical rapid thermal processing system includes a conical thermal radiation reflector and a plurality of elongated radiant heating sources within the conical thermal radiation reflector. The elongated radiant heating sources pass through an imaginary conical surface within the conical thermal radiation reflector. A wafer holder within the imaginary conical surface holds the wafer face transverse to the common axis of the conical reflector and the conically arranged radiant heating lamps. The conical thermal radiation reflector and conically arranged lamps provide uniform radiant heating across the face of a wafer without significantly degrading coupling efficiency.

    Abstract: In an apparatus for curing semiconductor wafers implementing same is provided. Pursuant to the method, semiconductor wafers, for example, GaAs, are cured in a reaction tube under a protective gas atmosphere of, for example, a mixture of N.sub.2 and AsH.sub.3. The reaction tube is initially heated to a base temperature at which the curing process is not initiated and at which no wall coatings occur. Given semiconductor wafers of compound semiconductors such as, for axample, GaAs, the protective atmosphere contains a compound of the more volatile element, for example, AsH.sub.3, that decomposes at the base temperature and forms an over-pressure of the more volatile element. The semiconductor wafer is heated to the curing temperature with a selective heater, for example a lamp, and is exposed to the curing temperature for 5 through 20 seconds.

    Abstract: A heat-treating apparatus includes a process tube accommodating an object to be heat-treated therein, and a plurality of independent heaters including at least three heaters arranged at both end portions and the central portion of a side wall of the process tube, so as to surround the process tube and, the heating temperatures of the individual heaters being freely adjustable. In this heat-treating apparatus, no direct heat transfer is caused between the heaters, so that the heating temperature of the heater at each end portion of the process tube can be adjusted to a high value, without entailing such an uneven temperature distribution as is caused in the case of a conventional heat-treating apparatus. Thus, uniform temperature distribution can be attained in an area covering the same range for the conventional apparatus, even though the heaters at both end portions are reduced in length.

    Abstract: A semiconductor wafer (1) is thermally treated in a prescribed heating cycle while it is introduced into a furnace casing (4) of a furnace (4) and discharged therefrom. A temperature of a monitor chip (11) is measured by a radiation thermometer (16) immediately before introduction of the semiconductor wafer and memorized as an idling temperature. Then, while the furnace is heated up in order to make a measured temperature of the monitor chip agree with the idling temperature without the semiconductor wafer introduced, a temperature of the furnace casing is measured by a radiation thermometer (8) and memorized as a warm-up temperature. The furnace is controlled on the basis of the warm-up temperature or the idling temperature prior to sequential heat treatment of a number of semiconductor wafers.
