  • Patent number: 10526242
    Abstract: Certain example embodiments of this invention relate to techniques for converting sputter-deposited TiNx or TiOxNy layers into TiOx layers via activation with electromagnetic radiation. An intermediate layer including TiOxNy, 0<y?1 is formed on a substrate. The intermediate layer is exposed to the radiation, which is preferentially absorbed by the intermediate layer in an amount sufficient to heat the intermediate layer to a temperature of 500-650 degrees C. while keeping the substrate at a significantly lower temperature. A flash light operated with a series of millisecond or sub-millisecond length pulses may be used in this regard. The converting removes nitrogen from, and introduces oxygen into, the intermediate layer, causing the layer to expand beyond its initial thickness. At least some of the final layer may have an anatase phase, and it may be photocatalytic. These layers may be used in low-maintenance glass, antireflective, and/or other applications.

    Abstract: The disclosure relates to a method of making molybdenum films utilizing boron and molybdenum nucleation layers. The resulting molybdenum films have low electrical resistivity, are substantially free of boron, and can be made at reduced temperatures compared to conventional chemical vapor deposition processes that do not use the boron or molybdenum nucleation layers. The molybdenum nucleation layer formed by this process can protect the substrate from the etching effect of MoCl5 or MoOCl4, facilitates nucleation of subsequent CVD Mo growth on top of the molybdenum nucleation layer, and enables Mo CVD deposition at lower temperatures. The nucleation layer can also be used to control the grain sizes of the subsequent CVD Mo growth, and therefore controls the electrical resistivity of the Mo film.

  • Patent number: 9452499
    Abstract: The invention refers to a method for applying heat resistant protection components onto the surface of a heat exposed component. The method including providing at least two separate heat protection components, and joining the at least two separate heat protection components onto their top surface and/or bottom surface and/or at least one side surface by flexible means for obtaining an integrally handable entity. The method further includes fixing the integrally handable entity by applying and brazing the surface of each heat protection component on the surface of the heat exposed component. The materials of the flexible means and for joining the flexible means on the separate heat protection components are selected such that the materials withstand brazing being performed under protective atmosphere, i.e. an atmosphere without or with reduced amount of oxygen, at process temperatures between 700° C. and 1200° C., and that the materials are burned out after brazing during a following oxidizing thermal step.

  • Patent number: 9211611
    Abstract: A method and system are provided for crystallizing thin films with a laser system. The method includes obtaining a thin film comprising a substrate and a target layer that contains nano-scale particles and is deposited on the substrate. The heat conduction between the target layer and the substrate of the thin film is determined based on thermal input from the laser system to identify operating parameters for the laser system that cause crystallization of the nano-scale particles of the target layer in an environment at near room temperature with the substrate remaining at a temperature below the temperature of the target layer. The laser system is then operated with the determined operating parameters to generate a laser beam that is transmitted along an optical path to impinge the target layer. The laser beam is pulsed to create a localized rapid heating and cooling of the target layer.
