Patent number: 8070555Abstract: A visual feedback system and method for airfoil polishing is disclosed. In one aspect there is a system for providing visual feedback during a polishing operation of a workpiece. In this system there is a model having a representation of a desired shape of the workpiece. A scanning system generates a representation of a current shape of the workpiece while in-process during the polishing operation. A comparator compares the current shape of the workpiece to the desired shape of the workpiece. An illumination system highlights the workpiece with visible light during the polishing operation. The highlighting of the workpiece with visible light is a function of the comparison between the current shape and the desired shape. The illumination system highlights a portion of the workpiece that needs additional polishing to conform to the desired shape.Type: GrantFiled: November 3, 2008Date of Patent: December 6, 2011Assignee: General Electric CompanyInventor: Douglas Carl Hofer

Patent number: 8052505Abstract: A wafer processing method for processing a wafer (20) having bumps (B) formed on a front surface (21) comprises the steps of: holding on a table (51), a bump region-conforming member (40) that has an outer shape conforming only to a bump region (25) where said bumps are formed in the wafer; forming a resin layer (29) by applying resin around the bump region-conforming member up to a thickness equal to or greater than that of the bump region-conforming member; grinding the bump region-conforming member along with the resin layer to a predetermined thickness; removing the bump region-conforming member from the table to form a concave part (45) in the resin layer; applying a film (11) on the front surface of the wafer; and disposing the wafer in the concave part of the resin layer and holding the wafer on the table so that a back surface (22) of said wafer faces upward. After that, the back surface of the wafer can also be ground.Type: GrantFiled: January 27, 2009Date of Patent: November 8, 2011Assignee: Tokyo Seimitsu Co., Ltd.Inventors: Masaki Kanazawa, Hajime Akahori
