Patent number: 8865259Abstract: Disclosed are an inline chemical vapor deposition method and system for fabricating a device. The method includes transporting a web or discrete substrate through a deposition chamber having a plurality of deposition modules. A buffer layer, a window layer and a transparent conductive layer are deposited onto the substrate during passage through a first deposition module, a second deposition module and a third deposition module, respectively. Advantageously, the steps for generating the buffer layer, window layer and transparent conductive layer are performed sequentially in a common vacuum environment of a single deposition chamber and the use of a conventional chemical bath deposition process to deposit the buffer layer is eliminated. The method is suitable for the manufacture of different types of devices including various types of solar cells such as copper indium gallium diselenide solar cells.Type: GrantFiled: June 9, 2011Date of Patent: October 21, 2014Assignee: Singulus MOCVD GmbH I.GR.Inventors: Piero Sferlazzo, Thomas Michael Lampros

Patent number: 8715777Abstract: In a method in which a cut line is formed on one surface of a planar glass material, and the cut line is allowed to extend in the thickness direction of the glass material, thereby cutting a glass substrate from the glass material, the cut line is selectively formed on a surface having relatively small surface waviness out of two opposing surfaces of the glass material. In the case of a glass material formed into a planar shape on a molten metal, the surface which has come into contact with the molten metal is selected as the surface having relatively small surface waviness. When a disk-shaped glass substrate is cut from the glass material, cutting is performed under conditions where either one of the thickness and the radius of the glass material and the maximum height of surface waviness of the glass material satisfy a predetermined relationship.Type: GrantFiled: April 30, 2012Date of Patent: May 6, 2014Assignee: Hoya CorporationInventors: Joseph Marquez, Elmer Mahia
