Patent number: 10974276Abstract: A system that reduces the amount of water that enters a process chamber via a movable shaft is disclosed. The surface of the shaft is made hydrophobic. Any water droplets that are collected on the hydrophobic shaft are disposed at a high contact angle, making it more likely that these water droplets fall from the shaft. Further, any water that enters the process chamber is more readily removed from the shaft due to the lower energy of liberation. Reducing the amount of water in a process chamber may improve the lifetime of the components in the process chamber and may improve the yield of the workpieces being processed. This may be especially relevant when process gasses that contain halogens are employed.Type: GrantFiled: January 8, 2020Date of Patent: April 13, 2021Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Ernest E. Allen, Jr., Jonathan David Fischer, Jeffrey E. Krampert

Patent number: 9520264Abstract: A system and method are disclosed for holding and cooling substrates during processing. A substrate clamp has an engagement portion for engaging a substrate about the inside diameter as well as a portion of the substrate surface immediately adjacent to the inside diameter. The clamp has a retracted position which enables the engagement portion to fit through the substrate ID, and an expanded position which enables the engagement portion to engage the substrate ID and the substrate surface immediately adjacent to the inside diameter. The clamp can include a conformal coating to enhance engagement between the substrate and the engagement portion. The clamp can also include an energy absorbing coating on one or more surfaces to maximize the absorption of radiative energy emitted from the substrate. Other embodiments are described and claimed.Type: GrantFiled: March 19, 2012Date of Patent: December 13, 2016Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Jeffrey E.

Patent number: 9218990Abstract: A substrate carrier includes a carrier plate, a cover plate and a plurality of substrate support slots. The carrier plate has recesses for receiving substrates. A sidewall of each recess includes protrusions for engaging the OD of a substrate. The cover plate is rotatable and has a cam on an undersurface. The cam is enagageable with a lateral slot in each of a plurality of substrate supports of the carrier plate. Rotating the cover plate causes the cam to move the substrate supports, one by one, so a substrate engaging end of the substrate support moves away from an associated substrate recess. A substrate is loaded into the recess, whereupon the cover plate is rotated further so the cam disengages from the lateral slot. The substrate supports are biased to engage the OD of the substrate to lock the substrate within the recess. Other embodiments are described and claimed.Type: GrantFiled: October 7, 2011Date of Patent: December 22, 2015Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: John Robert Fairhurst, Jeffrey E.

Patent number: 9212949Abstract: An improved system and method of measuring the temperature of a workpiece in a processing chamber is disclosed. Because silicon has very low emissivity in the infrared band, a coating is disposed on at least a portion of the workpiece. This coating may be graphite or any other material that can be readily applied, and has a relatively constant emissivity over temperature in the infrared spectrum. In one embodiment, a coating of graphite is applied to a portion of the workpiece, allowing the temperature of the workpiece to be measured by observing the temperature of the coating. This technique can be used to calibrate a processing chamber, validate operating conditions within the processing chamber, or to develop a manufacturing process.Type: GrantFiled: March 28, 2014Date of Patent: December 15, 2015Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Jeffrey E.

Patent number: 9175710Abstract: A ceramic fastener includes a ceramic body portion, and a containment layer disposed around the ceramic body portion. The containment layer retains pieces of the ceramic body portion when the ceramic body portion is subjected to a torque sufficient to fracture the ceramic body portion. The fastener can be a nut, and the containment layer can be disposed around one or more of the top, bottom and side surfaces of the nut. The containment layer can be a metal shroud having a thickness from 0.01 to 0.125 inches. The ceramic body portion can be alumina or zirconia. A thread insert may be disposed within a fastener bore of the ceramic body portion.Type: GrantFiled: December 19, 2013Date of Patent: November 3, 2015Assignee: Varian Semiconductor Equipment Associates, IncInventors: Michael A.

Patent number: 9070730Abstract: A system and method are disclosed for removing vertically oriented substrates from a cassette. A lifter includes a lifter notch and a stabilizer notch for holding a substrate. The lifter notch engages and lifts the substrate along the substrate ID, while the stabilizer notch captures the substrate OD to prevent lateral movement of the substrate during lifting. In use, the cassette is tilted to bias all substrates to one side and ensure consistent spacing. The lifter moves up into the cassette until the notches are adjacent, but beneath, the ID and OD of a substrate. The lifter is moved laterally to position the notches directly below the ID and OD. Upward movement of the lifter causes the lifter notch to lift the substrate along the ID. The lifter continues upward with the substrate until the substrate clears the top of the cassette. Other embodiments are described and claimed.Type: GrantFiled: October 7, 2011Date of Patent: June 30, 2015Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: John Robert Fairhurst, Jeffrey E.
