    摘要: A method and apparatus for targeting a beam of radiation is provided. A beam steering mirror and a beam capture mirror are movably disposed along an optical pathway. A controller moves the beam steering mirror and the beam capture mirror in an x-y plane, and rotates the mirrors, to target the beam to a target location on a surface, while keeping the optical path length substantially constant for all target locations on the surface. The surface is rotated by a rotational actuator to bring all target locations to positions accessible by the beam targeting optics. Imprecision in targeting and optical path length may be compensated by providing an actuated aperture at the beam entry point and/or a variable focus lens with an optical range finding detector, all in communication with the controller.

    摘要: Apparatus and methods for measuring the temperature of a substrate are disclosed. The apparatus includes a source of temperature-indicating radiation, a detector for the temperature-indicating radiation, and a decorrelator disposed in an optical path between the source of temperature-indicating radiation and the detector for the temperature-indicating radiation. The decorrelator may be a broadband amplifier and/or a mode scrambler. A broadband amplifier may be a broadband laser, Bragg grating, a fiber Bragg grating, a Raman amplifier, a Brillouin amplifier, or combinations thereof. The decorrelator is selected to emit radiation that is transmitted, at least in part, by the substrate being monitored. The source is matched to the decorrelator such that the emission spectrum of the source is within the gain bandwidth of the decorrelator, if the decorrelator is a gain-driven device.

    摘要: In a laser annealing system for workpieces such as semiconductor wafers, a pyrometer wavelength response band is established within a narrow window lying between the laser emission band and a fluorescence emission band from the optical components of the laser system, the pyrometer response band lying in a wavelength region at which the optical absorber layer on the workpiece has an optical absorption coefficient as great as or greater than the underlying workpiece. A multi-layer razor-edge interference filter having a 5-8 nm wavelength cut-off edge transition provides the cut-off of the laser emission at the bottom end of the pyrometer response band.
