20100162759 | HIGH PURITY FUSED SILICA WITH LOW ABSOLUTE REFRACTIVE INDEX - A fused silica glass article having a low absolute refractive index and low concentrations of hydroxyl groups, halogens, and metal having a low absolute refractive index. The glass article contains less than about 10 ppm protium-containing and deuterium-containing hydroxyl groups by weight and less than about 20 ppm halogens by weight. The silica glass article also has an absolute refractive index (ARI) less than or equal to 1.560820. In one embodiment, the ARI of the fused silica article is achieved by lowering the fictive temperature of the fused silica. A method of lowering the fictive temperature is also described. | 07-01-2010 |
20120006060 | Method of manufacturing glass substrate and method of manufacturing electronic components - A plurality of via-holes are formed in panel-shaped glass, and a plurality of via-holes are formed in two bases. Then, the panel-shaped glass is interposed between the two bases, positions of a plurality of the via-holes of the bases and a plurality of the via-holes of the panel-shaped glass are aligned, wires made of a conductive material are penetrated, and the wires between the two bases are stretched. Then, the panel-shaped glass is heated to a point higher than a softening point of the glass, the wires between the bases are buried by the glass, and the glass is cooled to form a glass ingot having the buried wires. Then, the ingot is sliced to form a glass substrate, the glass panel is polished to expose the wires on front and rear surfaces as the through electrodes. | 01-12-2012 |
20120006061 | Method of manufacturing glass substrate and method of manufacturing electronic components - Disclosed is a method of manufacturing a glass substrate with through electrodes, the method including: a wire stretching process in which a plurality of conductive wires are stretched in parallel between upper and lower bases; a wire burying process in which a plurality of the wires between the bases are buried by glass; an ingot formation process in which a glass ingot having the buried wires is formed by cooling the glass; a slicing process in which a glass panel is formed by slicing the glass ingot; and a polishing process in which a plurality of the wires are exposed on front and rear surfaces of the glass panel to provide the through electrodes. | 01-12-2012 |
