Publication number: 20020078893Abstract: A plasma enhanced chemical processing reactor and method. The reactor includes a plasma chamber including a first gas injection manifold and a source of electromagnetic energy. The plasma chamber is in communication with a process chamber which includes a wafer support and a second gas manifold. The plasma generated in the plasma chamber extends into the process chamber and interacts with the reactive gases to deposit a layer of material on the wafer. The reactor also includes a vacuum system for exhausting the reactor. The method includes the steps of generating a plasma within the plasma chamber, introducing at least one gaseous chemical into the process chamber proximate to the wafer support and applying r.f. gradient to induce diffusion of the plasma to the area proximate the wafer support.Type: ApplicationFiled: November 16, 2001Publication date: June 27, 2002Applicant: Applied Materials , Inc.Inventors: Ron van Os, William J. Durbin, Richard H. Matthiesen, Dennis C. Fenske, Eric D. Ross

Patent number: 5838528Abstract: An electrostatic support system for retaining a wafer. The support system generally includes a support body having a support surface for retaining said wafer, a voltage source coupled to the support body for electrostatically coupling the wafer to the support surface, and a cooling system for cooling the wafer. A plurality of arm members extend from the support body to a carriage assembly for releasably mounting the support body to the processing chamber with the support body and the arm members separated from the chamber floor. This invention also includes the method of supporting a wafer in a processing chamber which includes the steps of positioning the wafer on a wafer supporting surface, applying a voltage to an electrode assembly to electrostatically attract the wafer to the support surface and, after processing the wafer, substantially grounding the electrode assembly to sufficiently deactivate the electrostatic charge for release of the wafer from the support surface.Type: GrantFiled: June 26, 1997Date of Patent: November 17, 1998Assignee: Watkins-Johnson CompanyInventors: Ron van Os, Eric D.
