A technical object of the present invention is to devise a glass sheet that is suitable for supporting a substrate to be processed to be subjected to high-density wiring and has high end surface strength, and a method of manufacturing the glass sheet, to thereby contribute to an increase in density of a semiconductor package. The glass sheet of the present invention has a total thickness variation of less than 2.0 m, all or part of an end surface of the glass sheet including a melt-solidified surface.

A method of joining panels for a vitrine is disclosed. The ends of the panels to be joined are mitered cut and bonded with a suitable adhesive providing adequate adhesion and transparency. The joints are formed to provide a wedge-shape bond gap sufficient to allow application of the adhesive from the outside of the gap through capillary action. The adhesive may be catalyzed or ultraviolet- or light-hardened.

A method of continuously processing glass ribbon having a thickness 0.3 mm. The method includes providing a glass processing apparatus having a first processing zone, a second processing zone and a third processing zone. The glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. The feed rate of the glass ribbon is controlled through each processing zone using a global control device. A first buffer zone is provided between the first processing zone and the second processing zone in which the glass substrate is supported in a first catenary between two, spaced-apart, payoff positions. A second buffer zone is provided between the second processing zone and the third processing zone in which the glass substrate is supported in a second catenary between two, spaced-apart, payoff positions.

A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.

Methods of forming scribe vents in a strengthened glass substrate having a compressive surface layer and an inner tension layer are provided. In one embodiment, a first and second defect is formed to partially expose the inner tension layer. A first scribe vent may be generated in a first scribing direction by translating a laser beam and a cooling jet on a surface of the strengthened glass substrate at a first scribing speed. A second scribe vent intersecting the first scribe vent may be generated in a second scribing direction by translating the laser beam and the cooling jet on the surface of the strengthened glass substrate at a second scribing speed that is greater than the first scribing speed. The defects may be perpendicular to the scribing directions. In another embodiment, the first scribe vent may be fused at an intersection location prior to generating the second scribe vent.

A method for processing a transparent workpiece including directing a laser beam in a first orientation along a first beam pathway where a first portion of the laser beam includes a first laser beam focal line and generates an induced absorption to produce a first defect segment within the transparent workpiece. The method further includes adjusting the laser beam to a second orientation along a second beam pathway where a second portion of the laser beam includes a second laser beam focal line and generates the induced absorption to produce a second defect segment within the transparent workpiece. Each of the first and second laser beam focal lines include a circular angular spectrum within the transparent workpiece; and at least one of the laser beam focal lines include an internal focal line angle of greater than 10? relative to a plane orthogonal to the impingement surface at the impingement location.

An apparatus, method, and process that includes a substantially transparent substrate having a first surface, a second surface, and an edge extending around at least a portion of a perimeter of the substantially transparent substrate, wherein the edge is a laser induced channel edge having enhanced edge characteristics.
