  • Publication number: 20150092924
    Abstract: We disclose targets for generating x-rays using electron beams, along with their method of fabrication. The targets comprise a number of microstructures fabricated from an x-ray target material arranged in close thermal contact with a substrate such that the heat is more efficiently drawn out of the x-ray target material. This in turn allows irradiation of the x-ray generating substance with higher electron density or higher energy electrons, which leads to greater x-ray brightness, without inducing damage or melting. The microstructures may comprise conventional x-ray target materials (such as tungsten) that are patterned at micron-scale dimensions on a thermally conducting substrate, such as diamond. The microstructures may have any number of geometric shapes to best generate x-rays of high brightness and efficiently disperse heat. In some embodiments, the target comprising microstructures may be incorporated into a rotating anode geometry, to enhance x-ray generation in such systems.

    Abstract: A method is provided to isolated conductive pads on top of a multi-layer polymer device structure. The method utilizes laser radiation to ablate conductive material and create a non-conductive path, electrically isolating the conductive pads. The process is self-limiting and incorporates at least one layer within the stack that absorbs the radiation at the required wavelength. The prevention of radiation degradation of the underlying layers is achieved, as absorption of radiation occurs primarily on the surface of the structure, but not in any of the radiation sensitive underlying layers of the electronic device. The method preferably uses low energy infrared radiation which has been shown to produce little debris and no device degradation.

    Abstract: A new Rhenium alloy usable for improving the performance of emission filaments used in mass spectrometers or other similar scientific instruments, which is made by adding low level concentrations of Yttrium Oxide to Rhenium of less than 10%. This new alloy has demonstrated superior performance characteristics compared to pure Rhenium for this purpose. Filaments made from the Yttria/Rhenium alloy exhibit the same voltage, current and emission properties as Rhenium but have the added advantage of greatly decreasing warping during use. The Rhenium alloy filaments are usable with various shapes and configurations including straight filaments, multiple coiled filaments and pin shaped filaments. Electron microscopy and microscopy studies verify that the Yttria/Rhenium material of the new alloy has a smaller grain size and increased strength when compared to pure Rhenium, which accounts for the enhanced structural strength.

  • Patent number: 8021204
    Abstract: All lights generated in an organic compound layer are not taken out towards a TFT from a cathode as a transparent electrode. For instance, the light is emitted in a lateral direction (direction parallel to the substrate surface) but the light emitted in the lateral direction is not taken out resultantly, which leads to a loss. Therefore, a light emitting device structured so as to increase the amount of light taken out in a certain direction is provided as well as a method of manufacturing this light emitting device. As a result of etching treatment, an upper edge portion of an insulator (19) is curved to have a radius of curvature, a slope is formed along the curved face while partially exposing layers (18c and 18d) of a first electrode, and a layer (18b) of the first electrode is exposed in a region that serves as a light emitting region.
