Patent number: 7651955Abstract: Embodiments of the invention generally provide a method for depositing films or layers using a UV source during a photoexcitation process. The films are deposited on a substrate and usually contain a material, such as silicon (e.g., epitaxy, crystalline, microcrystalline, polysilicon, or amorphous), silicon oxide, silicon nitride, silicon oxynitride, or other silicon-containing materials. The photoexcitation process may expose the substrate and/or gases to an energy beam or flux prior to, during, or subsequent a deposition process. Therefore, the photoexcitation process may be used to pre-treat or post-treat the substrate or material, to deposit the silicon-containing material, and to enhance chamber cleaning processes.Type: GrantFiled: June 20, 2006Date of Patent: January 26, 2010Assignee: Applied Materials, Inc.Inventors: Joseph M. Ranish, Kaushal K. Singh

Patent number: 7648925Abstract: An improved barrier stack. The barrier stack is made by the process of depositing the polymeric decoupling layer on a substrate; depositing a first inorganic layer on the decoupling layer under a first set of conditions wherein an ion and neutral energy arriving at the substrate is less than about 20 eV so that the first inorganic layer is not a barrier layer, wherein a temperature of the substrate is less than about 150° C.; and depositing a second inorganic layer on the first inorganic layer under a second set of conditions wherein an ion and neutral energy arriving at the substrate is greater than about 50 eV so that the second inorganic layer is a barrier layer. Methods of reducing damage to a polymeric layer in a barrier stack are also described.Type: GrantFiled: July 12, 2007Date of Patent: January 19, 2010Assignee: Vitex Systems, Inc.Inventors: Lorenza Moro, Xi Chu

Patent number: 7642127Abstract: A method of sealing a microelectromechanical system (MEMS) device from ambient conditions is described, wherein the MEMS device is formed on a substrate and a substantially hermetic seal is formed as part of the MEMS device manufacturing process. The method comprises forming a metal seal on the substrate proximate a perimeter of the MEMS device using a method such as photolithography. The metal seal is formed on the substrate while the MEMS device retains a sacrificial layer between conductive members of MEMS elements, and the sacrificial layer is removed after formation of the seal and prior to attachment of a backplane.Type: GrantFiled: July 17, 2007Date of Patent: January 5, 2010Assignee: Qualcomm Mems Technologies, Inc.Inventor: Philip Floyd

Patent number: 7629206Abstract: Fabrication methods for making thin film devices on transparent substrates are described. Gate, source, and drain electrodes of a transistor are formed on a transparent substrate. The widths of the drain electrode and source electrodes are greater than a width of the gate electrode. A dielectric layer is formed on the gate electrode. A semiconductor layer is deposited proximate to the gate, source and drain electrodes. Photoresist is deposited on the semiconductor. The photoresist is exposed to light directed through the transparent substrate so that the gate electrode masks the photoresist from the light. The semiconductor layer is removed in regions exposed to the light.Type: GrantFiled: February 26, 2007Date of Patent: December 8, 2009Assignees: 3M Innovative Properties Company, Palo Alto Research Center IncorporatedInventors: Michael Albert Haase, Robert A.
