Patent number: 8083207Abstract: Improved gate movement is provided in a wet process environment in which fluid collecting from a gate occurs adjacent to an access opening provided in a wall of a process chamber while the gate is moved relative to the opening. A minimum space environment is adjacent to the chamber due to a requirement for fluid collection next to the opening, yet the gate movement is provided without interference with a wafer transfer unit that moves the wafer through the access opening. Drives are configured within the minimum space environment to move the gate into and out of alignment with the opening and when aligned, to move the gate into and out of a gate closure position. The configuration of the drives avoids interference with the wafer transfer unit and the gate is received in a fluid collector during the gate movement to provide fluid collection during the wafer transfer.Type: GrantFiled: November 11, 2008Date of Patent: December 27, 2011Assignee: Lam Research CorporationInventors: Jacob Wylie, Gregory A.

Publication number: 20080179010Abstract: A bevel etcher incorporating a vacuum chuck used for cleaning the bevel edge and for reducing the bending curvature of a semiconductor substrate. The bevel etcher includes a vacuum chuck and a plasma generation unit which energizes process gas into a plasma state. The vacuum chuck includes a chuck body and a support ring. The top surface of the chuck body and inner periphery of the support ring form a vacuum region enclosed by the bottom surface of a substrate mounted on the support ring. A vacuum pump evacuates the vacuum region during operation. The vacuum chuck is operative to hold the substrate in place by the pressure difference between the top and bottom surfaces of the substrate. The pressure difference also generates a bending force to reduce the bending curvature of the substrate.Type: ApplicationFiled: January 26, 2007Publication date: July 31, 2008Applicant: Lam Research CorporationInventors: Andrew D.

Publication number: 20030155079Abstract: A plasma processing system that includes a plasma processing chamber that provides enhanced control over an etch process is disclosed. The plasma processing chamber is connected to a gas flow system. The gas flow system can be employed to control the release of gases into different regions within the plasma processing chamber. In addition, the volume of the released gas, e.g., the flow rate of the gas, can be adjusted by a gas flow control mechanism. In this manner, both the position and the amount of the gas that is delivered to the plasma processing chamber can be controlled. The ability to adjust the position and the amount of gas that is released into the plasma processing chamber provides for a better control over the distribution of the neutral components. This in turn enhances control over the etching process.Type: ApplicationFiled: November 15, 1999Publication date: August 21, 2003Inventors: ANDREW D. BAILEY, ALAN M. SCHOEPP, DAVID J. HEMKER, MARK H.
