  • Publication number: 20080041831
    Abstract: The thermal processing device includes a stage, a continuous wave electromagnetic radiation source, a series of lenses, a translation mechanism, a detection module, a three-dimensional auto-focus, and a computer system. The stage is configured to receive a substrate thereon. The continuous wave electromagnetic radiation source is disposed adjacent the stage, and is configured to emit continuous wave electromagnetic radiation along a path towards the substrate. The series of lenses is disposed between the continuous wave electromagnetic radiation source and the stage, and are configured to condense the continuous wave electromagnetic radiation into a line of continuous wave electromagnetic radiation on a surface of the substrate. The translation mechanism is configured to translate the stage and the line of continuous wave electromagnetic radiation relative to one another. The detection module is positioned within the path, and is configured to detect continuous wave electromagnetic radiation.

  • Publication number: 20070293058
    Abstract: A thermal processing apparatus and method in which a first laser source, for example, a CO2 emitting at 10.6 ?m is focused onto a silicon wafer as a line beam and a second laser source, for example, a GaAs laser bar emitting at 808 nm is focused onto the wafer as a larger beam surrounding the line beam. The two beams are scanned in synchronism in the direction of the narrow dimension of the line beam to create a narrow heating pulse from the line beam when activated by the larger beam. The energy of GaAs radiation is greater than the silicon bandgap energy and creates free carriers. The energy of the CO2 radiation is less than the silicon bandgap energy so silicon is otherwise transparent to it, but the long wavelength radiation is absorbed by the free carriers.

Optionally, the layer further comprises a dopant selected from the group consisting of nitrogen, boron, phosphorus, fluorine, and combinations thereof. In one aspect, the layer comprising amorphous carbon is an anti-reflective coating and an absorber layer that absorbs the electromagnetic radiation and anneals a top surface layer of the substrate. In one aspect, the substrate is exposed to the electromagnetic radiation in a laser annealing process.

  • Publication number: 20070218644
    Abstract: The present invention generally describes one or more apparatuses and various methods that are used to perform an annealing process on desired regions of a substrate. In one embodiment, an amount of energy is delivered to the surface of the substrate to preferentially melt certain desired regions of the substrate to remove unwanted damage created from prior processing steps (e.g., crystal damage from implant processes), more evenly distribute dopants in various regions of the substrate, and/or activate various regions of the substrate. The preferential melting processes will allow more uniform distribution of the dopants in the melted region, due to the increased diffusion rate and solubility of the dopant atoms in the molten region of the substrate. The creation of a melted region thus allows: 1) the dopant atoms to redistribute more uniformly, 2) defects created in prior processing steps to be removed, and 3) regions that have hyper-abrupt dopant concentrations to be formed.

  • Publication number: 20060286763
    Abstract: Embodiments of the invention generally provide a method for forming a doped silicon-containing material on a substrate. In one embodiment, the method provides depositing a polycrystalline layer on a dielectric layer and implanting the polycrystalline layer with a dopant to form a doped polycrystalline layer having a dopant concentration within a range from about 1×1019 atoms/cm3 to about 1×1021 atoms/cm3, wherein the doped polycrystalline layer contains silicon or may contain germanium, carbon, or boron. The substrate may be heated to a temperature of about 800° C. or higher, such as about 1,000° C., during the rapid thermal anneal. Subsequently, the doped polycrystalline layer may be exposed to a laser anneal and heated to a temperature of about 1,000° C. or greater, such within a range from about 1,050° C. to about 1,400° C., for about 500 milliseconds or less, such as about 100 milliseconds or less.

  • Patent number: 7041931
    Abstract: In a system for thermal processing of a semiconductor substrate, a reflector plate has a stepped surface facing the substrate during heating and cooling of the substrate. The raised surface of the reflector plate has reduced reflectivity, providing advantages during, among other things, cooling of the substrate. The reflector plate also includes a number of recesses to which one or more pyrometers are coupled. These recesses have a highly reflective surface, providing advantages in the performance of the pyrometers.
