Patent number: 7480129Abstract: A detachable electrostatic chuck can be attached to a pedestal in a process chamber. The electrostatic chuck has an electrostatic puck comprising a dielectric covering at least one electrode and a frontside surface to receive a substrate. A backside surface of the chuck has a central protrusion that can be a D-shaped mesa to facilitate alignment with a mating cavity in the pedestal. The protrusion can also have asymmetrically offset apertures, which further assist alignment, and also serve to receive electrode terminal posts and a gas tube. A heat transfer plate having an embedded heat transfer fluid channel is spring loaded on the pedestal to press against the chuck for good heat transfer.Type: GrantFiled: September 7, 2005Date of Patent: January 20, 2009Assignee: Applied Materials, Inc.Inventors: Karl Brown, Semyon Sherstinsky, Wei W.

Publication number: 20070261951Abstract: The present invention generally comprises one or more cooled anodes shadowing one or more gas introduction tubes where both the cooled anodes and the gas introduction tubes span a processing space defined between one or more sputtering targets and one or more substrates within a sputtering chamber. The gas introduction tubes may have gas outlets that direct the gas introduced away from the one or more substrates. The gas introduction tubes may introduce reactive gas, such as oxygen, into the sputtering chamber for depositing TCO films by reactive sputtering. During a multiple step sputtering process, the gas flows (i.e., the amount of gas and the type of gas), the spacing between the target and the substrate, and the DC power may be changed to achieve a desired result.Type: ApplicationFiled: April 6, 2007Publication date: November 15, 2007Inventors: Yan Ye, Ankur Kadam, Yanping Li, Allen Lau, Makoto Inagawa, Bradley Stimson, Akihiro Hosokawa

Patent number: 7252737Abstract: Generally, a substrate support member for supporting a substrate is provided. In one embodiment, a substrate support member for supporting a substrate includes a body coupled to a lower shield. The body has an upper surface adapted to support the substrate and a lower surface. The lower shield has a center portion and a lip. The lip is disposed radially outward of the body and projects towards a plane defined by the first surface. The lip is disposed in a spaced-apart relation from the body. The lower shield is adapted to interface with an upper shield disposed in a processing chamber to define a labyrinth gap that substantially prevents plasma from migrating below the member. The lower shield, in another embodiment, provides the plasma with a short RF ground return path.Type: GrantFiled: April 6, 2004Date of Patent: August 7, 2007Assignee: Applied Materials, Inc.Inventors: Karl Brown, Vineet Mehta, See-Eng Phan, Semyon Sherstinsky, Allen Lau

Publication number: 20060151306Abstract: An apparatus for a lock out/tag out device that is a permanent attachment to a standard breaker box is disclosed. The device is designed to prevent movement of an electrical breaker handle to a closed position when the device is in use. The device also prevents locking a breaker in an on position, thereby lowering safety concerns. When the device is not in use, the device will not interfere with the operation of the breakers and stays conveniently attached to the breaker box. The device also allows storage of locking devices when not in use, thereby enabling personnel to perform a service procedure more efficiently.Type: ApplicationFiled: December 20, 2005Publication date: July 13, 2006Inventors: Allen Lau, Michael Rosenstein, Carl Johnson, Sharon Niehoff
