Publication number: 20230049196Abstract: Methods of producing a glass article include melting a first glass composition and feeding a second glass composition into the melter. Both glass compositions include the same combination of components but at least one component has a concentration that is different in each. At least three glass articles may be drawn from the melter, including: a first glass article formed from the first glass composition; at least one intermediate glass article composed of neither the first nor the second glass composition; and a final glass article not composed of the first glass composition. The concentration of the at least one component in the intermediate glass article may be between the concentration in the first and second glass compositions.

Patent number: 11328950Abstract: Embodiments of the disclosure relate to a method for fabricating semiconductor-on-insulator (SemOI) electronic components. In the method, a device wafer is bonded to a handling wafer. The device wafer includes a semiconductor device layer and a buried oxide layer. A substrate is adhered to the handling wafer. The substrate is a glass or a ceramic, and bonding occurs at an interface between the semiconductor device layer and the substrate. Material is removed from the device wafer to expose the buried oxide layer. The substrate is debonded from the handling wafer so as to provide an SemOI electronic component including the substrate, the semiconductor device layer, and the buried oxide layer.Type: GrantFiled: January 20, 2021Date of Patent: May 10, 2022Assignee: Corning IncorporatedInventors: Ya-Huei Chang, Jen-Chieh Lin, Jian-Zhi Jay Zhang
