Fusion Bonding Of Glass To A Formed Part Patents (Class 65/36)
  • Patent number: 10126061
    Abstract: Methods and systems for localized strengthening of features of a component formed from a sapphire material include a combination of holistic heating and localized surface heating. In one example, the localized heating may occur via laser thermal, flame polishing, hot wire heating, plasma etching, or chemical treatment. By combining the localized surface heating with holistic heating, near-melt or melt processing in a localized area can be achieved while avoiding overheating of well-polished areas, and therefore minimizing defects that would otherwise be caused by excessive heating. This may be used for strengthening features of components formed from sapphire material that are difficult to polish, such as non-planar features.

  • Patent number: 8980115
    Abstract: A cover glass element can extend to the edges of an electronic device while maintaining the optical flatness and thickness needed for the cover glass. A first glass sheet with the desired thickness and flatness can be thermally bonded to a second glass sheet machined to include an opening to be received by the edges of the electronic device. The resulting three-dimensional cover element forms a uni-body frame that is significantly stiffer than a single sheet of glass, and the larger surface area of the edge provides for enhances pressure distribution, particularly after chemical strengthening, thus enhancing the durability of the electronic device. Further, the thermal bonding process uses lower temperatures than processes such as slumping or pressing, which could potentially affect the flatness and optical clarity of the original sheet glass.

    Abstract: An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.

  • Patent number: 8434328
    Abstract: An antimony-free glass suitable for use in a frit for producing a hermetically sealed glass package is described. The hermetically sealed glass package, such as an OLED display device, is manufactured by providing a first glass substrate plate and a second glass substrate plate and depositing the antimony-free frit onto the first substrate plate. OLEDs may be deposited on the second glass substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first glass substrate plate to the second glass substrate plate and also protects the OLEDs. The antimony-free glass has excellent aqueous durability, good flow, low glass transition temperature and low coefficient of thermal expansion.

  • Patent number: 8424746
    Abstract: To easily bond substrates even made of materials whose linear expansion coefficients are different from each other when manufacturing an optical component used by transmitting light through an inside thereof. Buffer layers made of an amorphous inorganic substance causing a brittle fracture are formed on bonding surfaces of a plurality of substrates having linear expansion coefficients different from one another, and the substrates to be bonded are stacked so that the buffer layers are faced to each other. Then, a heat treatment is performed for a stack, and thereby direct bonding via an atom is formed between the buffer layers.

  • Publication number: 20130095260
    Abstract: Methods for ultrashort pulse laser processing of optically transparent materials. A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with side-illumination and not clearly visible without side-illumination. In addition, a method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. The ultrashort pulse duration causes nonlinear absorption of the laser radiation, and the high repetition rate of the laser causes pulse-to-pulse accumulation of heat within the materials.

  • Publication number: 20130071601
    Abstract: A cover glass element can extend to the edges of an electronic device while maintaining the optical flatness and thickness needed for the cover glass. A first glass sheet with the desired thickness and flatness can be thermally bonded to a second glass sheet machined to include an opening to be received by the edges of the electronic device. The resulting three-dimensional cover element forms a uni-body frame that is significantly stiffer than a single sheet of glass, and the larger surface area of the edge provides for enhances pressure distribution, particularly after chemical strengthening, thus enhancing the durability of the electronic device. Further, the thermal bonding process uses lower temperatures than processes such as slumping or pressing, which could potentially affect the flatness and optical clarity of the original sheet glass.

  • Patent number: 8387413
    Abstract: In a known method for producing a component with a layer of transparent quartz glass, comprising: applying particles of synthetically produced quartz glass to a base body made of quartz glass and sintering the particles so as to form the quartz glass layer. Starting therefrom, in order to permit a comparatively inexpensive and reproducible production of a component with at least one layer of transparent quartz glass that is distinguished by ultrahigh purity and the absence of bubbles, it is suggested according to the invention that at least part of the SiO2 particles should be present in the form of cylindrical fragments of quartz glass fibers having a mean diameter ranging from 0.1 mm to 3 mm and a mean length ranging from 0.5 mm to 20 mm.

    Abstract: A method for manufacturing a light-emitting-element mounting substrate includes a step of applying a glass paste using powder of a glass material having a softening point higher than a softening point of a glass component contained in a glass-ceramic green sheet and lower than a melting point of silver so as to cover a conductor paste which is applied to a main surface of the glass-ceramic green sheet and consists of or consists primarily of silver; and a step of coating a metal layer obtained by heating them and sintering the conductor paste, with a transparent glass layer obtained by melting and then cooling the glass paste. By using the glass paste, the reaction of silver in the conductor paste with the glass component in the glass paste upon heating is suppressed, and the metal layer can be coated with the glass layer having high transparency.
