Patent number: 7842931Abstract: An extraction electrode manipulator system, comprising an ion source, a suppression electrode and a ground electrode, wherein the two electrode are supported by coaxially arranged two water cooled support tubes. A high voltage insulator ring is located on the other end of the coaxial support tube system to act as a mechanical support of the inner tube and also as a high voltage vacuum feedthrough to prevent sputtering and coating of the insulating surface.Type: GrantFiled: September 25, 2008Date of Patent: November 30, 2010Assignee: Axcelis Technologies, Inc.Inventors: Shu Satoh, John Adamik, Manny Sieradzki

Patent number: 6167834Abstract: A high pressure, high throughput, single wafer, semiconductor processing reactor is disclosed which is capable of thermal CVD, plasma-enhanced CVD, plasma-assisted etchback, plasma self-cleaning, and deposition topography modification by sputtering, either separately or as part of in-situ multiple step processing. The reactor includes cooperating arrays of interdigitated susceptor and wafer support fingers which collectively remove the wafer from a robot transfer blade and position the wafer with variable, controlled, close parallel spacing between the wafer and the chamber gas inlet manifold, then return the wafer to the blade. A combined RF/gas feed-through device protects against process gas leaks and applies RF energy to the gas inlet manifold without internal breakdown or deposition of the gas. The gas inlet manifold is adapted for providing uniform gas flow over the wafer.Type: GrantFiled: August 13, 1992Date of Patent: January 2, 2001Assignee: Applied Materials, Inc.Inventors: David Nin-Kou Wang, John M.

Patent number: 5871811Abstract: A method for protecting a selected area of a substrate against deposition on the selected area. The method includes the steps of flowing a process gas into a substrate processing chamber and flowing a purge gas to the selected area of the substrate to prevent the process gas from contacting the selected area or minimize contact between the process gas and the selected area. In various embodiments the selected area is a backside periphery of the substrate or the edge of the substrate. Also in these embodiments, the process gas is flowed into a deposition zone in order to deposit a thin film layer over an upper surface of the substrate, and a flow of the process and purge gas is established such that the process gas flows radically across the upper surface of the substrate, combines with the purge gas near an edge of the substrate and exits the processing chamber through an exhaust system.Type: GrantFiled: June 7, 1995Date of Patent: February 16, 1999Assignee: Applied Materials, Inc.Inventors: David Nin-Kou Wang, John M.

Patent number: 5755886Abstract: A substrate processing reactor capable of thermal CVD, plasma-enhanced CVD, plasma-assisted etchback, plasma self-cleaning and other substrate processing operations all of which can either be performed separately or as part of in-situ multiple step processing. The reactor incorporates a uniform radial gas pumping system which enables uniform reactant gas flow across the wafer. Also included are upper and lower purge gas dispersers. The upper purge gas disperser directs purge gas flow downwardly toward the periphery of the wafer while the lower gas disperser directs purge gas across the backside of the wafer. The radial pumping gas system and purge gas dispersers sweep radially away from the wafer to prevent deposition external to the wafer and keep the chamber clean.Type: GrantFiled: June 7, 1995Date of Patent: May 26, 1998Assignee: Applied Materials, Inc.Inventors: David Nin-Kou Wang, John M.

Patent number: 5354715Abstract: A high pressure, high throughout, single wafer semiconductor processing reactor is disclosed which is capable of thermal CVD, plasma-enhanced CVD, plasma-assisted etchback, plasma self-cleaning and deposition topography modification by sputtering, either separately or as part of in-situ multiple step processing. The reactor provides uniform processing over a wide range of pressures including very high pressures. A low temperature process for forming a highly conformal layer of silicon dioxide from a plasma of TEOS, oxygen and ozone is also disclosed. This layer can be planarized using an etchback process. Silicon oxide deposition and etchback can be carried out sequentially in the reactor.Type: GrantFiled: April 1, 1992Date of Patent: October 11, 1994Assignee: Applied Materials, Inc.Inventors: David N-K.
