摘要： An aluminosilicate glass, including in mole percent on an oxide basis, MgO + CaO + SrO + Li 2 O + ZnO + Y 2 O 3 + ZrO 2 + La 2 O 3 + TiO 2 + Nb 2 O 5 + Ta 2 O 5 in a range of from 5 mol% to 25 mol%. The glass is processable by (i) flowing the glass in a molten state over forming surfaces to form a glass ribbon, the forming surfaces converging at a root and (ii) drawing the glass ribbon using pulling rollers to form a glass sheet, wherein the pulling rollers are spaced at a pulling roller distance from the root, and wherein the glass exhibits a viscosity curve slope obtained by plotting a temperature gradient to increase a root viscosity of the glass at the root, to a higher viscosity at one of several positions between the root and the pulling rollers, and a viscosity of the glass at the pulling rollers. The glass comprises a liquidus viscosity, the root viscosity being less than the liquidus viscosity, and the glass comprising a viscosity curve slope that prevents a baggy warp defect. In certain embodiments, when the root viscosity of the glass is in a range of from about 70 kP to about 90 kP, and the viscosity of the glass at the pulling rollers is greater than 90 kP and less than or equal 1 X 10 8 kP, the temperature gradient is less than 150 °C.

摘要： A method and apparatus for processing glass comprising a forming apparatus in a first processing zone, the forming apparatus configured to form a glass ribbon having a first direction of travel in the first processing zone. The apparatus also includes a first cutting apparatus in a second processing zone, the first cutting apparatus configured to separate one or more portions of the glass ribbon, the glass ribbon having a second direction of travel. The apparatus includes a first buffer zone between the first processing zone and the second processing zone in which the glass ribbon is supported in a first catenary between two, spaced-apart payoff positions. The second direction of travel in the second processing zone can be orthogonal to the first direction of travel in the first processing zone.

摘要： Disclosed herein are methods for making a thin film device and/or for reducing warp in a thin film device, the methods comprising applying at least one metal film to a convex surface of a glass substrate, wherein the glass substrate is substantially dome-shaped. Other methods disclosed include methods of determining the concavity of a glass sheet. The method includes determining the orientation of the concavity and measuring a magnitude of the edge lift of the sheet when the sheet is supported by a flat surface and acted upon by gravity. Thin film devices made according to these methods and display devices comprising such thin film devices are also disclosed herein.

摘要： A non-polished glass wafer, a thinning system, and a method for using the non-polished glass wafer to thin a semiconductor wafer are described herein. In one embodiment, the glass wafer has a body (e.g., circular body) including a non-polished first surface and a non-polished second surface substantially parallel to each other. In addition, the circular body has a wafer quality index which is equal to a total thickness variation in micrometers plus one-tenth of a warp in micrometers that is less than 6.0.
