  • Publication number: 20230174420
    Abstract: A method of fabricating a metal thin film-on-glass structure. A glass substrate, on a top surface of which a layer is formed, is prepared. A local area of the glass substrate is etched from a bottom of the glass substrate to expose the layer downwardly, thereby forming an exposed area of the layer. The layer is a metal thin film. The etching includes first-etching the glass substrate to a depth less than a thickness of the glass substrate using a first etching solution containing hydrofluoric acid and at least one of nitric acid and sulfuric acid, resulting in a first-etched portion of the glass substrate; and second-etching the first-etched portion of the glass substrate using an etching solution containing hydrofluoric acid without nitric acid or sulfuric acid, so that the layer is exposed downwardly, whereby the metal thin film is supported by a remaining portion of the glass substrate.

  • Patent number: 9169154
    Abstract: A method of cutting chemically toughened glass which is chemically toughened in a chemical toughening process of creating compressive stress in the surface of glass by exchanging first alkali ions in the glass with second alkali ions. The method includes the steps of applying a paste on a portion of the chemically toughened glass that is to be cut, heating the paste, and cutting the chemically toughened glass along the portion on which the paste is applied. The paste contains alkali ions. The ion radius of the alkali ions in the paste is smaller than an ion radius of the second alkali ions which substitute the first ions in the chemical toughening process.

  • Patent number: 9030664
    Abstract: An apparatus for measuring transmissivity of a patterned glass substrate. A beam radiator radiates a laser beam. A collimation lens collimates the laser beam radiated from the laser beam radiator. A beam expander expands a size of the laser beam collimated by the collimation lens. A detector has a light-receiving section, which receives the laser beam that has passed through the patterned glass substrate after having been expanded by the beam expander. A measuring instrument measures a transmissivity of the patterned glass substrate using the laser beam received by the detector.
