Patent number: 7413272Abstract: The present invention provides methods and apparatus for controlling the quantity of fluid output (e.g., drop size) by individual nozzles of a print head to a very high precision at a frequency equal to the frequency at which fluid is normally dispensed. This is achieved by mapping fluid quantity control information into the data that represents the image to be printed. Data representative of an image is received and converted into pixel data. In at least one embodiment, the pixel data includes pixels represented by N bits, and the N bits may represent a drop size for the pixel and a union of the N bits may represent a nozzle status. A print head may be controlled based on the pixel data, and the print head may include nozzles that are each adapted to deposit at least one drop size quantity of a fluid on a substrate.Type: GrantFiled: February 18, 2005Date of Patent: August 19, 2008Assignee: Applied Materials, Inc.Inventors: Bassam Shamoun, Janusz Jozwiak, Quanyuan Shang, Hongbin Ji

Publication number: 20080190765Abstract: The invention relates to a magnetron with a planar target and a planar magnet system. The planar magnet system comprises a bar-shaped first magnet pole with enlarged ends and a frame-shaped second magnet pole, wherein a relative movement between the magnet poles and the target is such that every point of the magnet system moving with the target being stationary moves on a circular path. If the magnet system is stationary, each point of the target moves on such a circular path. During the relative movement with respect to one another the magnet system and the target are in parallel planes. The diameter of the circular path corresponds to the mean distance between two parallel arms of a plasma tube, which during the sputter operation develops between the first and the second magnet pole. Thereby that the magnets in the curve region of the plasma tube are disposed such that the pole lines form at this site a circle arc or a circular area, holes in the target are avoided.Type: ApplicationFiled: June 4, 2005Publication date: August 14, 2008Applicant: Applied Materials GmbH & Co.KGInventors: Andreas Lopp, Manfred Ruske

Patent number: 7410737Abstract: A method to extend the process monitoring capabilities of a semiconductor wafer optical inspection system so as to be able to detect low-resolution effects of process variations over the surface of a wafer at much higher sensitivity than heretofore possible. The method consists, in essence, of grouping sensed pixels by geometric blocks over the inspected surface and comparing each block with a corresponding one from another die on the same wager, from another wager of from a stored model image. In one embodiment of the invention, pixel values are compared directly and differences are thresholded at a considerably lower level than during a defects detection process. In another embodiment, there is calculated a signature for each block, based on the sensed light intensity values, and corresponding signatures are compared.Type: GrantFiled: April 17, 2006Date of Patent: August 12, 2008Assignee: Applied Materials Israel, Ltd.Inventors: Evgeni Levin, Gilad Almogy, Efrat Rozenman

Publication number: 20080184933Abstract: A process chamber 1 for PECVD (Plasma Enhanced Chemical Vapor Deposition) coating of a substrate includes an electrode, which is integrated in a contact frame, which is firmly connected to the recipient. A movable carrier in the process chamber carries at least one substrate. The carrier is transported by means of a driven roller positioner into the process chamber or out of the process chamber along a transport route defined by the movement. As soon as the carrier inside the recipient has reached a certain position, the lower roller positioner is uncoupled from carrier by lowering by means of a lifting device. In this regard, the carrier detaches itself from the upper roller positioner. Then, the carrier is accepted by a transfer device (not shown) and brought from the transport position laterally into a treatment position in contact with the contact frame. In this way, reliable contact is produced between the electrode and a counter-electrode provided in carrier.Type: ApplicationFiled: February 28, 2007Publication date: August 7, 2008Applicant: Applied Materials, Inc.Inventors: Juergen Henrich, Michael Schaefer, Edgar Haberkorn
