    Abstract: Embodiments of the present disclosure generally relate to methods and apparatus for visual lamp failure detection in a processing chamber, such as an RTP chamber. Visual feedback is facilitated through the use of a wide-angle lens positioned to view lamps within the process chamber. The wide-angle lens is positioned within a probe and secured using a spring in order to withstand high temperature processing. A camera coupled to the lens is adapted to capture an image of the lamps within the process chamber. The captured image of the lamps is then compared to a reference image to determine if the lamps are functioning as desired.

    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.

    Abstract: Embodiments described herein provide apparatus and methods for processing semiconductor substrates with uniform laser energy. A laser pulse or beam is directed to a spatial homogenizer, which may be a plurality of lenses arranged along a plane perpendicular to the optical path of the laser energy, an example being a microlens array. The spatially uniformized energy produced by the spatial homogenizer is then directed to a refractive medium that has a plurality of thicknesses. Each thickness of the plurality of thicknesses is different from the other thicknesses by at least the coherence length of the laser energy.

    Abstract: Examples described herein generally relate to apparatus and methods for rapid thermal processing (RTP) of a substrate. The present disclosure discloses pulsed radiation sources used to measure a broad range of low to high temperatures in the RTP chamber, each at a discrete wavelength, are used at a low temperature regime before using one laser at a discrete wavelength for higher temperatures. In another example, a single laser is used for both the low temperature regime and higher temperatures. These methods are useful for detection of a broad range of low to high temperatures in the RTP chamber with varying substrate types.

    Abstract: The present invention generally describes apparatuses and methods used to perform an annealing process on desired regions of a substrate. In one embodiment, pulses of electromagnetic energy are delivered to a substrate using a flash lamp or laser apparatus. The pulses may be from about 1 nsec to about 10 msec long, and each pulse has less energy than that required to melt the substrate material. The interval between pulses is generally long enough to allow the energy imparted by each pulse to dissipate completely. Thus, each pulse completes a micro-anneal cycle. The pulses may be delivered to the entire substrate at once, or to portions of the substrate at a time. Further embodiments provide an apparatus for powering a radiation assembly, and apparatuses for detecting the effect of pulses on a substrate.
