Publication number: 20020029978Abstract: The present invention is directed to a method and apparatus for plating a surface of a semiconductor workpiece (wafer, flat panel, magnetic films, etc.) using a liquid conductor that makes contact with the outer surface of the workpiece. The liquid conductor is stored in a reservoir and pump through an inlet channel to the liquid chamber. The liquid conductor is injected into a liquid chamber such that the liquid conductor makes contact with the outer surface of the workpiece. An inflatable tube is also provided to prevent the liquid conductor from reaching the back face of the workpiece. A plating solution can be applied to the front face of the workpiece where a retaining ring/seal further prevents the plating solution and the liquid conductor from making contact with each other. In an alternative embodiment, electrical contacts may be formed using an inflatable tube that has either been coated with a conductive material or contains a conductive object.Type: ApplicationFiled: June 7, 2001Publication date: March 14, 2002Applicant: Nutool, Inc.Inventors: Homayoun Talieh, Bulent Basol
