Patent number: 6322337Abstract: The present invention provides systems and methods of dispensing liquids. In one embodiment, the system includes a pump with a removable pump module with at least one displacement piston and at least one piston valve. A motor and base assembly provide the supporting components of the pump which can be used in environments where precise small volumes of ultra-pure liquids must be transferred from a reservoir to a point of use. The preferred embodiment of the system prevents contaminants and air bubbles from being introduced into the liquid to be dispensed by placing a filter across the discharge line downstream from the pump, and providing a separate drawback line for performing the drawback of the liquid in the dispensing nozzle.Type: GrantFiled: July 24, 1999Date of Patent: November 27, 2001Assignees: Ivek Corporation, Silicon Valley Group, Inc.Inventors: Douglas S. Bensley, John E. Barney, Frank Dimaggio, Mark Tanny, Dikran Babikian

Patent number: 6141203Abstract: An electrostatic chuck is provided having a plurality of small electrostatic structures for holding an electrically conductive workpiece forming a plate of a capacitor. Each electrostatic structure includes a first thermally conductive single-crystal dielectric sheet, and a first electrode in sheet form sandwiched between the first dielectric sheet and a second dielectric surface. The workpiece, typically a conductive or semiconductive wafer, is juxtaposed to the first dielectric sheet of each electrostatic structure and forms a second electrode. The second dielectric sheet, if thick, is used as a thermally conducting base plate which can be attached to a low pressure reactor. If the second dielectric is a thin sheet, then it is mounted to a thermally conductive metal base plate through which heat can be controllably conducted. The resultant electrostatic structure may be brazed to the metal base plate if the thermal expansion characteristics of the two elements are sufficiently matched.Type: GrantFiled: November 7, 1997Date of Patent: October 31, 2000Inventor: Arthur Sherman

Patent number: 6136111Abstract: Disclosed are compositions that are useful as microgas-generators, which can be used as propellants in airbags or seatbelt pretensioners. The compositions use a fuel which comprises an organic compound having a high ratio of the number of reactive carbon-oxygen groups to the total number of carbon atoms. The compositions also optionally use an oxidizer to supply oxygen to the fuel and/or a binding agent to form the fuel and optional oxidizer into particles. The compositions are useful as ignitors or squibbs, and can be used in industrial tools, seatbelt pretensioning systems, and airbags.Type: GrantFiled: October 20, 1999Date of Patent: October 24, 2000Assignee: Quantic Industries, Inc.Inventors: Kelly W. Lemons, Albert J. Baggett, Jr., William D. Fahey, Lawrence Weinman

Patent number: 6098843Abstract: The present invention relates to chemical delivery systems and methods for delivery of liquid chemicals. In one embodiment, the present invention relates to systems having multi-reservoir load cell assemblies for delivering chemicals used in the semiconductor industry. In one embodiment, the present invention provides a multi-reservoir load cell assembly, including a controller, a buffer reservoir, a main reservoir, one or more load cells, coupled to the assembly and to the controller, operable to weigh the liquid in the reservoir(s), a plurality of supply lines, each supply line having a valve and connecting one of the supply containers to the main reservoir, and a gas and vacuum sources for withdrawing the liquid from the assembly when demanded by the controller and for refilling the assembly from the supply containers.Type: GrantFiled: December 31, 1998Date of Patent: August 8, 2000Assignees: Silicon Valley Group, Inc., Semco CorporationInventors: David Soberanis, Randy Forshey

Patent number: 6091056Abstract: The invention provides a hot plate oven suitable to bake materials on substrates such as flat panel displays and large semiconductor wafers such as 300 mm in diameter and above. The hot plate oven in one embodiment includes an insulated chamber, a heater in the chamber, a door for entry of a substrate, a frame, preferably water cooled, for suspending the substrate above the heater, a substrate lowering mechanism to hold the frame and lower the substrate to a certain height above the heater at least one fluid cooled pin to counteract sag when the substrate is heated, and a set of manifolds and valves to feed and exhaust gases, vapors, and apply a vacuum to the chamber. In another feature, the oven assembly includes a stack of low profile ovens, each having a door on the side for entry of a substrate.Type: GrantFiled: September 26, 1997Date of Patent: July 18, 2000Assignee: Silicon Valley Group, Inc.Inventors: Chak D. Kannan, Adam Jerome Weber

Patent number: 5997650Abstract: An apparatus for adjusting the tension on a heating filament in a reactor used in carbon deposition on a substrate via chemical-vapor deposition is disclosed, as is a method for preventing breakage of the filaments during operation. The apparatus comprises a force regulator attached to an array of heating filaments. Preferably, the force regulator is adjustable and is adjusted prior to reactor operation and/or periodically or continuously as the filaments lengthen due to carburization in the carbon-vapor environment of the reactor. The adjustable force regulator attached to an array of filaments enables effective regulation of the force on a filament during reactor operation and provides an easily-maintained reactor with quick turn-around time between cycles of use.Type: GrantFiled: November 6, 1998Date of Patent: December 7, 1999Assignee: Sp.sup.3, Inc.Inventors: James E. Herlinger, David K. Studley, Jerry W. Zimmer
