Patent number: 6627051Abstract: A cathode current control system employing a current thief for use in electroplating a wafer is set forth. The current thief comprises a plurality of conductive segments disposed to substantially surround a peripheral region of the wafer. A first plurality of resistance devices are used, each associated with a respective one of the plurality of conductive segments. The resistance devices are used to regulate current through the respective conductive finger during electroplating of the wafer. Various constructions are used for the current thief and further conductive elements, such as fingers, may also be employed in the system. As with the conductive segments, current through the fingers may also be individually controlled. In accordance with one embodiment of the overall system, selection of the resistance of each respective resistance devices is automatically controlled in accordance with predetermined programming.Type: GrantFiled: July 20, 2001Date of Patent: September 30, 2003Assignee: Semitool, Inc.Inventors: Robert W. Berner, Joseph J. Fatula, Jr., Robert Hitzfeld, Richard Contreras, Andrew Chiu

Patent number: 6599415Abstract: A method and apparatus for electropolishing a workpiece without immersing the workpiece in a bath of electrolytic solution. The workpiece is held in an atmospheric environment, while electrolytic solution is discharged from a reservoir in the form of a plurality of jet streams onto the surface of the workpiece. A voltage difference is applied across the workpiece and the jet streams, thereby inducing a current to flow, between the workpiece acting as anode and the jet streams acting as cathode. The workpiece may be rotated about an axis and moved linearly along the same axis while the jet streams of electrolytic solution are discharged onto the workpiece. Anodic dissolution causes polishing of the workpiece surface. The electrolytic solution may be collected after discharge and recycled back into the reservoir, after being filtered and cooled.Type: GrantFiled: April 30, 2001Date of Patent: July 29, 2003Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Yu-Chun Ku, Ryan John Santos
