Publication number: 20070012341Abstract: An elevated pressure and temperature fluid processing system providing a pressurized fluid delivery system including a process fluid supply system and pump for supplying a process fluid at a process pressure, and a process fluid heater for heating the process fluid; a process chamber with a process chamber heater; and a process discharge collection system. The system also provides a process chamber inflow valve for connecting the pressurized fluid delivery system to the process chamber for fluid flow, and a process chamber outflow valve for connecting the process chamber to the collection system for fluid flow. A process chamber bypass valve connects the pressurized fluid delivery system to the process discharge collection system so as to bypass the process chamber. A computer control system controls the pump, the process fluid heater, the chamber heater, and the valves.Type: ApplicationFiled: August 31, 2006Publication date: January 18, 2007Inventors: Stephen Douglas, Rick White, Keith Pope, David Mount, Heiko Moritz

Patent number: 7108001Abstract: A supercritical fluid cleaning system uses process fluid for operating rotary motors in the chamber with fluid bearings and fluid load levitation for rotating workpieces and impellers. Rotating speed and direction sensors and a home position locator facilitate motor control. Impellers add further agitation of the fluid in the chamber, faster processing, and greater uniformity of supercritical fluid components and increase mass transfer of fluid to the processed surface. Centrifugal operated clips and cassettes hold wafers and impellers. Non-contact, fluid operated rotating mechanisms reduce contamination. Physical, rotational, and shear affects are enhanced through centrifugal forces which can induce the separation of films localized deposits or molecular products of the reaction from the surface. There is a concomitant agitation of fluid, and continuous angular acceleration imparted to the processed surface features.Type: GrantFiled: April 5, 2004Date of Patent: September 19, 2006Inventors: Keith Pope, David J Mount, Laura Rothman, Rick C White, Clifton Busby, Stephen B Douglas, Raymond J Doww, III

Publication number: 20060029310Abstract: Device for fluidic support and bi-directional rotation of an item in a process chamber where the operating fluid is compatible with the process. The device has a rotable load bearing platform with a load bearing interface between it and a base in the chamber. Fluid, which may be supercritical fluid, is applied through load bearing ports into the interface to fluidly support the weight and create rotational forces on the load platform. A turbine on the load platform is actuated by fluid flow directed from turbine ports in the chamber connected to the fluid source. Markers on the load platform and sensors in the chamber provide speed and direction sensing. An electromagnetic source in the chamber reacts with a permanent magnet in the rotable platform to provide an electromagnetic force for moving, or changing or holding the relative position of the load platform.Type: ApplicationFiled: April 5, 2005Publication date: February 9, 2006Applicant: S.C.

Publication number: 20050211269Abstract: A surface cleaning apparatus comprising a chamber, and a thermal transfer device. The chamber is capable of holding a semiconductor structure therein. The thermal transfer device is connected to the chamber. The thermal transfer device has a surface disposed inside the chamber for contacting the semiconducting structure and controlling a temperature of the semiconductor structure in contact with the surface. The thermal transfer device has a thermal control module connected to the surface for heating and cooling the surface to thermally cycle the surface. The thermal control module effects a substantially immediate thermal response of the surface when thermally recycling the surface.Type: ApplicationFiled: May 12, 2005Publication date: September 29, 2005Inventors: John Simons, Kenneth McCullough, Wayne Moreau, John Cotte, Keith Pope, Charles Taft, Dario Goldfarb
