Patent number: 7952851Abstract: An electrostatic chuck and method for clamping and de-clamping a workpiece is provided. The ESC comprises a clamping plate having a clamping surface, and one or more electrodes. An electric potential applied to the one or more electrodes selectively clamps the workpiece to the clamping surface. An arc pin operably coupled to the clamping plate and a power source provides an arc for penetrating an insulating layer of the workpiece. The arc pin is selectively connected to an electrical ground, wherein upon removal of the insulative layer of the workpiece, the arc pin provides an electrical ground connection to the workpiece.Type: GrantFiled: October 31, 2008Date of Patent: May 31, 2011Assignee: Axcelis Technologies, Inc.Inventors: Marvin R. LaFontaine, Ari Eiriksson, Ashwin M. Purohit, William D. Lee

Patent number: 7100759Abstract: A vertical rapid thermal processing system includes a processing chamber and an elevator structure providing for vertical movement of a workpiece within the processing chamber. The elevator structure includes a workpiece support for supporting the workpiece and an elevator shaft coupled to the workpiece support and extending externally from the processing chamber. An end portion of the elevator shaft, external to the processing chamber, has a selected magnetic polarity. The elevator structure also includes moveable carriage coupled to the shaft to provide vertical movement of the workpiece within the processing chamber. The carriage includes a shaft support having the selected polarity. The shaft support is positioned adjacent the polarized end portion of the elevator shaft such that repulsive magnetic forces maintain a gap between the end portion of the elevator shaft and the shaft support as the shaft support and elevator shaft move vertically along a path of travel.Type: GrantFiled: August 9, 2004Date of Patent: September 5, 2006Assignee: Axcelis Technologies, Inc.Inventors: Michel Pharand, Dennis Normandin, Ari Eiriksson

Patent number: 7070661Abstract: A workpiece is supported on a gas cushion to reduce mechanical stresses on the workpiece during processing. A plenum having a workpiece support flange for receiving the workpiece is connected to a gas supply. When gas flows into the plenum and pressure increases sufficiently to lift the workpiece, the workpiece is lifted and the gas flows out of the plenum between the flange and the workpiece edge. The workpiece is thus supported above the flange by the gas during processing.Type: GrantFiled: August 22, 2003Date of Patent: July 4, 2006Assignee: Axcelis Technologies, Inc.Inventors: Ari Eiriksson, Richard Gueler, Michel Pharand

Patent number: 7026581Abstract: A wafer support position control mechanism selectively positions a semiconductor wafer along an axis of excursion within a process chamber. An elevator tube protrudes through an orifice in the chamber surface and is connected at a first distal end to the wafer support. A compliant, dynamic seal within the orifice engages the elevator tube to form a gas curtain within a gap between the seal and the elevator tube to seal the process chamber. A moveable carriage is connected to the elevator tube at a second distal end for moving the wafer support along the axis of excursion. Rigid mechanical structure couples the second distal end of the elevator tube to the moveable carriage.Type: GrantFiled: August 22, 2003Date of Patent: April 11, 2006Assignee: Axcelis Technologies, Inc.Inventors: Michel Pharand, Thomas L.
