Patent number: 7834994Abstract: An apparatus and method incorporating at least two sensors that detect the presence of a substrate is provided. In one embodiment, a method for transferring a substrate in a processing system is described. The method includes positioning a substrate on an end effector in a first chamber, moving the substrate through an opening between the first chamber and a second chamber along a substrate travel path, and sensing opposing sides of the substrate travel path using at least two sensors positioned proximate to the opening, each of the at least two sensors defining a beam path that is directed through opposing edge regions of the substrate when at least a portion of an edge region traverses the beam path.Type: GrantFiled: October 21, 2008Date of Patent: November 16, 2010Assignee: Applied Materials, Inc.Inventors: William A. Bagley, Paohuei Lee, Kyung-Tae Kim, Sam-Kyung Kim, Toshio Kiyotake, Sam Kim, Takayuki Matsumoto, Jonathan Erik Larson, Makoto Inagawa, James Hoffman, Billy C. Leung

Patent number: 7641247Abstract: Generally, an end effector assembly for a substrate transfer robot is provided. In one embodiment, an end effector assembly for supporting a quadrilateral substrate during substrate transfer includes an end effector having an inner edge support disposed on a first end and a first outer edge support disposed on a distal end. The first end of the end effector is adapted for coupling to a robot linkage. The first inner edge support has a face that is oriented parallel to and facing the face of the first outer edge support. This configuration of edge supports captures the substrate to the end effector thereby minimizing substrate slippage during transfer. In another embodiment, lateral guides may be utilized to further enhance capturing the substrate along the edges of the substrate open between the inner and outer edge supports.Type: GrantFiled: December 17, 2002Date of Patent: January 5, 2010Assignee: Applied Materials, Inc.Inventors: Wendell T. Blonigan, Takayuki Matsumoto, William N. Sterling, Billy C. Leung

Patent number: 7575220Abstract: Embodiments of an apparatus for sealing a substrate transfer passage in a chamber are provided. In one embodiment, an apparatus for sealing a substrate transfer passage in a chamber includes an elongated door member having a convex sealing face and a backside. In another embodiment, a chamber having an apparatus for sealing a substrate transfer passage is provided that includes a chamber body having an interior volume, at least one substrate access defined through the chamber body configured to allow passage of a large area substrate therethrough, and a door member having a convex sealing face moveable between a first position that covers the substrate transfer port and a second position clear of the substrate transfer port. In yet another embodiment, the chamber body may be a load lock chamber.Type: GrantFiled: June 14, 2004Date of Patent: August 18, 2009Assignee: Applied Materials, Inc.Inventors: Yoshiaki Tanase, Billy C.

Patent number: 7440091Abstract: An apparatus and method incorporating at least two sensors that detect the presence of substrate defects, such as breakage or misalignment, along the lengths of at least two parallel edges of a moving substrate. In one embodiment, an apparatus for detecting substrate defects includes a sensor arrangement including at least two sensors that continuously sense a substrate near at least two parallel edges of the substrate as the substrate passes the sensors. In another embodiment, an apparatus for detecting substrate defects includes a robot having a substrate support surface, and a sensor arrangement including at least two sensors that continuously sense a substrate near at least two parallel edges of the substrate during substrate transfer on the substrate support surface.Type: GrantFiled: October 26, 2004Date of Patent: October 21, 2008Assignee: Applied Materials, Inc.Inventors: William A. Bagley, Paohuei Lee, Kyung-Tae Kim, Sam-Kyung Kim, Toshio Kiyotake, Sam Kim, Takayuki Matsumoto, Jonathan Erik Larson, Makoto Inagawa, James Hoffman, Billy C. Leung

Patent number: 6047082Abstract: An automatic system for inspecting contact lenses that are suspended in a saline solution within a lens holder. In the manufacturing process a first electronic image is taken of each lens disposed in its holder. Thereafter a second image is taken of the lens after the holder has been rotated and the solution and lens have moved. The two images are compared and any dark spots on the first image that move with respect to the second image are eliminated as artifacts that are caused by contaminants in the solution or marks on the lens holder. The rim of the lens, optical zone, printed logo and colored iris area of the lens are automatically inspected by a computer program for defects. The lens is rejected if defect features are found in any of the inspected areas.Type: GrantFiled: November 14, 1997Date of Patent: April 4, 2000Assignee: Wesley Jessen CorporationInventors: Harvey E.
