Publication number: 20140058266Abstract: A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.Type: ApplicationFiled: August 20, 2013Publication date: February 27, 2014Inventors: Josef R. Call, Kenneth D.

Publication number: 20060111575Abstract: The non-routine (e.g., emergency) shutdown of a chemical reaction process is achieved by a method of safely operating a chemical reaction process which comprises the steps of detecting an undesirable condition capable of affecting the process, minimizing the reaction of the reactants, and maintaining a flow of materials through the reaction zones of the process such that the reaction mixture is displaced from the reaction zones. The flow of materials may be maintained for a period of time such that the substantially all of the reaction mixture is displaced from the reaction zones, thereby flushing the reaction zones. The reaction mixture may then be purged to an ancillary vessel, such as an absorber.Type: ApplicationFiled: November 7, 2005Publication date: May 25, 2006Inventors: Michael DeCourcy, Nam Le

Patent number: 6843881Abstract: In a substrate processing apparatus, a substrate processing chamber has a substrate support to support a substrate, a gas delivery system to provide an energized cleaning gas to the chamber to clean process residues formed on surfaces in the chamber during processing of the substrate, and an exhaust to exhaust the cleaning gas. A detector monitors a chemiluminescent radiation emitted from about a surface during cleaning of the process residues by the energized cleaning gas and generates a signal in relation to the monitored chemiluminescent radiation. A controller receives the signal and evaluates the signal to determine an endpoint of the cleaning process.Type: GrantFiled: April 2, 2002Date of Patent: January 18, 2005Assignee: Applied Materials, Inc.Inventors: Bok Hoen Kim, Nam Le, Martin Seamons, Ameeta Madhava, Michael P.

Patent number: 6436303Abstract: A method and device for removing film from a substrate are provided that take advantage of a remote plasma source to etch away undesired portions of films, such as dielectric films formed on a substrate. To that end, the method includes forming a plasma remotely with respect to the process chamber, from which a flow is created that is directed toward the substrate. The substrate is of a type having opposed major surfaces with a peripheral surface extending therebetween. A film, such as a dielectric film, is disposed on one of the opposed major surfaces and on the peripheral surface. The opposed major surface having the film thereon is shielded from the flow of reactive radicals while the peripheral surface is left exposed. In this fashion, the flow is maintained for a sufficient amount of time to remove film present on the peripheral surface.Type: GrantFiled: July 21, 1999Date of Patent: August 20, 2002Assignee: Applied Materials, Inc.Inventors: Bok Heon Kim, Nam Le, Joseph V.

Patent number: 6413321Abstract: Backside particle contamination of semiconductor wafers subjected to chemical vapor deposition is significantly reduced by optimizing various process parameters, alone or in combination. A high quality oxide seasoning layer is deposited to improve adhesion and trapping of contaminants remaining after a prior chamber cleaning step. Second, wafer pre-heating reduces thermal stress on the wafer during physical contact between the wafer and heater. Third, the duration of the gas stabilization flow of thermally reactive process gas species prior to CVD reaction is reduced, thereby preventing side products produced during this stabilization flow from affecting the wafer backside. Fourth, the wafer heater is redesigned to minimize physical contact between the heater surface and the wafer backside.Type: GrantFiled: December 7, 2000Date of Patent: July 2, 2002Assignee: Applied Materials, Inc.Inventors: Bok Hoen Kim, Mario Dave Silvetti, Ameeta Madhava, Davood Khalili, Martin Seamons, Emanuele Cappello, Nam Le, Lloyd Berken
