Publication number: 20150062688Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.Type: ApplicationFiled: November 5, 2014Publication date: March 5, 2015Inventors: Robin Friedman, Sridhar Kailasam, Rao Mulpuri, Ronald Powell, Dhairya Shrivastava

Publication number: 20130312835Abstract: A gas expansion module for use with semiconductor wafer loadlocks and other regulated-pressure components of semiconductor processing tools is provided. The gas expansion module may be barometrically isolated from the loadlock or other component and pumped down to a vacuum condition while the loadlock is performing operations at a higher pressure, such as ambient atmospheric conditions. After an initial pump-down of the loadlock is performed, the gas expansion module may be fluidly joined to the loadlock volume and the gases within each allowed to reach equilibrium. A further pump-down of the combined volume may be used to bring the loadlock pressure to a desired vacuum condition.Type: ApplicationFiled: May 23, 2013Publication date: November 28, 2013Inventors: Edmund B.

Patent number: 8053861Abstract: Provided are methods and apparatuses for depositing barrier layers for blocking diffusion of conductive materials from conductive lines into dielectric materials in integrated circuits. The barrier layer may contain copper. In some embodiments, the layers have conductivity sufficient for direct electroplating of conductive materials without needing intermediate seed layers. Such barrier layers may be used with circuits lines that are less than 65 nm wide and, in certain embodiments, less than 40 nm wide. The barrier layer may be passivated to form easily removable layers including sulfides, selenides, and/or tellurides of the materials in the layer.Type: GrantFiled: January 26, 2009Date of Patent: November 8, 2011Assignee: Novellus Systems, Inc.Inventors: Thomas W.
