Publication number: 20100037823Abstract: The present invention generally relates to a gas distribution showerhead and a shadow frame for an apparatus. By extending the corners of the gas distribution showerhead the electrode area may be expanded relative to the anode and thus, uniform film properties may be obtained. Additionally, the expanded corners of the gas distribution showerhead may have gas passages extending therethrough. In one embodiment, hollow cathode cavities may be present on the bottom surface of the showerhead without permitting gas to pass therethrough. The shadow frame in the apparatus may also have its corner areas extended out to enlarge the anode in the corner areas of the substrate being processed and thus, may lead to deposition of a material on the substrate having substantially uniform properties.Type: ApplicationFiled: August 7, 2009Publication date: February 18, 2010Applicant: APPLIED MATERIALS, INC.Inventors: TOM K.

Patent number: 7523163Abstract: A distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. Client computers can connect to any available server computer and start or join a conference hosted on either the server computer to which the client computer is connected or any other server in the system. As a result, the system and method of the present invention is easily scalable to support an arbitrary number of participants to a conference by merely adding the appropriate number of server computers to the system. In addition, by replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer.Type: GrantFiled: July 3, 2006Date of Patent: April 21, 2009Assignee: Cisco Technology, Inc.Inventors: Min Zhu, Jian Shen, Steven Li, Guanghong Yang, Bin Zhao, Shi Yan, Zheng Yuan

Patent number: 7459405Abstract: Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.Type: GrantFiled: July 25, 2006Date of Patent: December 2, 2008Assignee: Applied Materials, Inc.Inventors: Nitin K.
