  • Patent number: 7695598
    Abstract: A coater having a substrate cleaning device is disclosed. The substrate cleaning device comprises an ion gun (i.e., an ion source) that is positioned beneath a path of substrate travel (e.g., beneath a substrate support) extending through the coater and that is adapted for treating a bottom major surface of a substrate. Certain embodiments involve an upward coating apparatus that is further along the path of substrate travel than the substrate cleaning device. In some embodiments of this nature, the upward coating apparatus is configured for depositing a photocatalytic coating upwardly onto the bottom major surface of the substrate. Certain embodiments of the invention involve a downward coating apparatus, wherein the substrate cleaning device is further along the path of substrate travel than the downward coating apparatus. Some embodiments involve an upward coating apparatus that is further along the path of substrate travel than the substrate cleaning device.

  • Patent number: 7679063
    Abstract: A method of and apparatus for identifying the presence of thin photocatalytic (PCAT) coatings on glass surfaces. An apparatus is disclosed that can determine whether a PCAT coating (which may comprise titanium dioxide, for example) having a thickness of less than about 100 ? is present on the surface of a substrate such as glass. The apparatus may measure the reflectance of electromagnetic energy (such as light energy) at the surface of a substrate using energy at selected wavelengths or wavelength ranges. The apparatus may determine reflectance values for PCAT coated surfaces of any thickness, as well as for uncoated surfaces.

  • Patent number: 7465378
    Abstract: The invention is a method for obtaining a reactive sputtering process with a reduced or eliminated hysteresis behavior. This is achieved by focusing the ion current onto a small area, a reduced erosion area (14), which is in constant motion along the target (10) to avoid melting of target material. This means that the current density is very high at the reduced erosion area (14) while the average overall current density is significantly lower. The problem with arcing during reactive sputtering will be suppressed since the compound layer is effectively removed if the current density is sufficiently high. Moreover, the high current density results in a substantial increase of the fraction of ionized sputtered species.
