  • Publication number: 20150041841
    Abstract: A method for fabricating an LED/phosphor structure is described where an array of blue light emitting diode (LED) dies are mounted on a submount wafer. A phosphor powder is mixed with an organic polymer binder, such as an acrylate or nitrocellulose. The liquid or paste mixture is then deposited over the LED dies or other substrate as a substantially uniform layer. The organic binder is then removed by being burned away in air, or being subject to an O2 plasma process, or dissolved, leaving a porous layer of phosphor grains sintered together. The porous phosphor layer is impregnated with a sol-gel (e.g., a sol-gel of TEOS or MTMS) or liquid glass (e.g., sodium silicate or potassium silicate), also known as water glass, which saturates the porous structure. The structure is then heated to cure the inorganic glass binder, leaving a robust glass binder that resists yellowing, among other desirable properties.

  • Publication number: 20130183457
    Abstract: The present invention fabricates a hydrophobic and oleophobic polymer fabric through two stages of modification using atmospheric plasmas. The modified fabric has a rough surface and a fluorocarbon functional group having the lowest surface free energy. The fabric has a grafted fluorocarbon monomer layer to enhance the graft efficiency of the fluorocarbon functional groups and its wash fastness. The atmospheric plasmas can be mass produced and less expensively. Hence, the present invention can rapidly modify surfaces of polymeric materials with low cost and good environment protection.

  • Publication number: 20130149462
    Abstract: A method of forming a dielectric layer is described. The method first deposits a silicon-nitrogen-and-hydrogen-containing (polysilazane) layer by radical-component chemical vapor deposition (CVD). The silicon-nitrogen-and-hydrogen-containing layer is formed by combining a radical precursor (excited in a remote plasma) with an unexcited carbon-free silicon precursor. A silicon oxide capping layer may be formed from a portion of the carbon-free silicon-nitrogen-and-hydrogen-containing layer to avoid time-evolution of underlying layer properties prior to conversion into silicon oxide. Alternatively, the silicon oxide capping layer is formed over the silicon-nitrogen-and-hydrogen-containing layer. Either method of formation involves the formation of a local plasma within the substrate processing region.

    Abstract: The disclosure is directed to a method of making yttrium oxide, Y2O3, coatings on substrates suitable for use at infrared wavelengths, including use in the 2-12 ?m range. The coating method eliminates or substantially eliminates the absorptions peaks that typically appear at approximately 3.0 ?m, 6.6 ?m and 7.1 ?m. This is achieved by using Y metal as the yttrium source in combination with an oxygen-containing plasma to form the Y2O3, coating in place of the using Y2O3 as the coating material source The disclosure is further directed to optics suitable for use in the infrared that have such coatings. The transmission spectrum of the coated substrate made according to the method described herein is greater than the transmission spectrum of the uncoated substrate over the wavelength range of 4 ?m to 12 ?m.

  • Patent number: 8404302
    Abstract: A solution process is provided for forming a textured transparent conductive oxide (TCO) film. The process provides a substrate, and forms a first layer on the substrate of metal oxide nanoparticles such as ZnO, In2O3, or SnO2. The metal oxide nanoparticles have a faceted structure with an average size greater than 100 nanometers (nm). Voids between the metal oxide nanoparticles have a size about equal to the size of the metal oxide nanoparticles. Then, a second layer is formed overlaying the first layer, filling the voids between the nanoparticles of the first layer, and completely covering the substrate. The result is a continuous TCO film having an average surface roughness that is created by the combination of first and second layers.
