  • Patent number: 10438860
    Abstract: The implementations described herein generally relate to steps for the dynamic, real-time control of the process spacing between a substrate support and a gas distribution medium during a deposition process. Multiple dimensional degrees of freedom are utilized to change the angle and spacing of a substrate plane with respect to the gas distributing medium at any time during the deposition process. As such, the substrate and/or substrate support may be leveled, tilted, swiveled, wobbled, and/or moved during the deposition process to achieve improved film uniformity. Furthermore, the independent tuning of each layer may be had due to continuous variations in the leveling of the substrate plane with respect to the showerhead to average effective deposition on the substrate, thus improving overall stack deposition performance.

Sets of isothermal plasma operating conditions have been found that create a narrow deposition zone, assuring that the deposited material is clear glass rather than soot particles. The chemical delivery system, in one arrangement, utilizes rods of solid phase source material (which may otherwise be difficult to obtain in gaseous form). The operating conditions are selected such that the hot plasma does not transfer a substantial amount of heat to the substrate tube, where the presence of such heat has been found to result in vaporizing the reactant material (creating soot) and developing hot spots.

  • Patent number: 8815337
    Abstract: Polymer-based optically-variable devices (OVDs) for security applications and methods for producing the same. The uniformity of thickness of the structure of such devices is optimized by controlling previously neglected process parameters such as the temperature distribution of the deposition nozzle, the substrate and the deposition drum, their emissivities, the micro-roughness of the substrate, and the rate of monomer re-evaporation. Re-evaporation is minimized by initiating radiation-curing within two seconds of monomer deposition. A method includes equipment reducing all sources of emissivity non-homogeneities, such as surface blemishes in the surface areas exposed to the substrate to preferentially fabricate substrates with haziness less than 5% and gloss greater than 90%. Controlling, a maximum variation of thickness of the transmissive layer of an OVD ensures that no appreciable color-shift variation is visible to the naked eye.

  • Patent number: 7985443
    Abstract: The invention relates to a self-cleaning lighting device comprising a light source and a wall, which permits a portion of at least the radiation emitted by said source to pass therethrough and which is covered, over a portion of at least one of its two faces, by a photocatalytically active layer. The invention is characterized in that under the weakest illumination conditions, the photocatalytic activity of said layer is high enough for degrading and reducing organic soilings into easily eliminable particles that do not adhere to said layer, and/or for conferring a hydrophilic character to this layer. The invention also relates to a method for producing the aforementioned device, a translucent wall provided for this device, and to the use of the device for lighting tunnels, public lighting, airport runway lighting, indoor lighting or for headlamps or indicator lights of transportation vehicles.

  • Patent number: 7968201
    Abstract: A multi-layer thin film stack, particularly suitable as a component of a solar cell, is deposited on a transparent dielectric substrate. The multi-layer film stack comprises a transparent electrically conductive metal oxide layer deposited over the dielectric substrate, the conductive metal oxide layer having a refractive index less than 2.0, a light transmittance optimizing interlayer having a refractive index between 2.3 and 3.5, deposited over the electrically conductive metal oxide layer, and a silicon layer having a refractive index of at least 4.5 deposited over the light transmittance optimizing interlayer. The film stack can be deposited by any suitable method, but deposition of each of these layers by atmospheric chemical vapor deposition is preferred.

  • Patent number: 7964238
    Abstract: A method of making a heat treated (HT) coated article to be used in shower door applications, window applications, or any other suitable applications where transparent coated articles are desired. For example, certain embodiments of this invention relate to a method of making a coated article including a step of heat treating a glass substrate coated with at least a layer of or including diamond-like carbon (DLC) and an overlying protective film (e.g., of or including zinc oxide) thereon. In certain example embodiments, the protective film may be ion beam treated with at least carbon ions. It has been found that the ion beam treatment improves the shelf-life of the product prior to HT. Following and/or during heat treatment (e.g., thermal tempering, or the like), the protective film may be removed.

  • Patent number: 7939129
    Abstract: A method is defined for producing an iron oxide coating on a glass article. The article is preferably for use as an architectural glazing. The method includes providing a heated glass substrate having a surface on which the coating is to be deposited. Ferrocene and an oxidant are directed toward and along the surface to be coated, and the ferrocene and the oxidant are reacted at or near the surface of the glass substrate to form an iron oxide coating.

  • Patent number: 7923063
    Abstract: This invention relates to a method of making glass. In certain example embodiments, a major surface(s) of the glass is treated with aluminum chloride (e.g., AlCl3). This treating, or application of an aluminum chloride based layer on the glass substrate, may be performed using combustion deposition. The combustion deposition may be performed at or just prior to the annealing lehr in certain example embodiments, or at any other suitable location. The aluminum chloride barrier layer, applied at a desirable glass temperature, helps to reduce sodium leaching or diffusion from the glass during conditions such as high heat and/or humidity, thereby improving the durability and/or stability of the resulting product.

  • Patent number: 7914857
    Abstract: There is provided a method of making a heat treated (HT) coated article to be used in shower door applications, window applications, or any other suitable applications where transparent coated articles are desired. The method may include heat treating a glass substrate coated with at least a layer of or including diamond-like carbon (DLC) or other type of carbon, with an oxygen barrier layer provided thereon directly or indirectly. Optionally, a release layer of a material such as zinc oxide or the like may be provided between the oxygen barrier layer and the DLC. In certain example embodiments, the oxygen content of at least part of the protective film when deposited may be determined based on whether the coated surface is to be bent in a convex manner, to be bent in a concave manner, or to remain flat. Following heat treatment, which may include bending the coated surface into a convex or concave shape, and quenching, the protective film may be removed by washing or the like.
