Patent number: 6764873Abstract: A semiconductor wafer provided with a thermosetting porous insulating film, wherein the insulating film is made porous, cured and polymerized on the wafer. The film is characterized by a very low dielectric constant based on its constituency and porosity, the latter property of which is caused by the inclusion of liquid or supercritical carbon dioxide in the polymeric reaction mixture.Type: GrantFiled: July 18, 2002Date of Patent: July 20, 2004Assignee: International Business Machines CorporationInventors: Habib Hichri, Kelly Malone, Arthur Martin

Publication number: 20040067309Abstract: A method and device of treating an irregularly shaped article to prepare the article for painting is provided. The device includes a burner which can produce an adjustable flame tongue which can fit into crevices, openings and other irregular topographical features of an item to be painted or otherwise coated. The burner device further provides means to apply a grafting chemical on a freshly oxidized surface. Further, the invention provides means to colorize treated objects so that they may be recognized as having been treated. In another embodiment, the grafting chemicals may be enhanced with electrolytic solutions such that electrostatic methods of painting may be subsequently employed on the item. In an alternate embodiment, the burner is adapted to spray a powder inside of a generally enclosed flame, and is used in conjunction with chop guns to manufacture glass or carbon fiber preforms.Type: ApplicationFiled: October 2, 2003Publication date: April 8, 2004Applicant: FTS Systems LLC (aka FTS LLC)Inventors: Russell Brynolf, Michael D. Elberson

Patent number: 6511718Abstract: A venturi mist generator creates a mist comprising droplets having a mean diameter less than one micron from liquid precursors containing multi-metal polyalkoxide compounds. The mist is mixed and then passed into a gasifier where the mist droplets are gasified at a temperature of between 100° C. and 250° C., which is lower than the temperature at which the precursor compounds decompose. The gasified precursor compounds are transported by carrier gas through insulated tubing at ambient temperature to prevent both condensation and premature decomposition. The gasified precursors are mixed with oxidant gas, and the gaseous reactant mixture is injected through a showerhead inlet into a deposition reactor in which a substrate is heated at a temperature of from 300° C. to 600 ° C. The gasified precursors decompose at the substrate and form a thin film of solid material on the substrate. The thin film is treated at elevated temperatures of from 500° C. to 900° C.Type: GrantFiled: December 17, 1999Date of Patent: January 28, 2003Assignee: Symetrix CorporationInventors: Carlos A.

Patent number: 6495378Abstract: A Pb3GeO5 phase PGO thin film is provided. This film has ferroelastic properties that make it ideal for many microelectromechanical applications or as decoupling capacitors in high speed multichip modules. This PGO film is uniquely formed in a MOCVD process that permits a thin film, less than 1 mm, of material to be deposited. The process mixes Pd and germanium in a solvent. The solution is heated to form a precursor vapor which is decomposed. The method provides deposition temperatures and pressures. The as-deposited film is also annealed to enhanced the film's ferroelastic characteristics. A ferroelastic capacitor made from the present invention PGO film is also provided.Type: GrantFiled: March 21, 2001Date of Patent: December 17, 2002Assignee: Sharp Laboratories of America, Inc,Inventors: Tingkai Li, Fengyan Zhang, Yoshi Ono, Sheng Teng Hsu

Patent number: 6475570Abstract: A method and apparatus for delivering a fine mist of a lubricant to a micromechanical device. A mixture 402 of a lubricant and a diluent carrier fluid is held in a supply reservoir 404. The mixture is forced through a nebulizer tip 406 to produce a fine aerosol. A particle selector 408 removes large droplets from the aerosol as the aerosol passes. The aerosol travels a distance through a delivery conduit 410 while the diluent carrier fluid evaporates from the nebulized droplets. The evaporation removes the vast majority of the diluent carrier fluid from the droplets, greatly reducing the size of the lubricant droplets. The evaporated aerosol enters a deposition chamber 412 and is deposited on a micromechanical device 414. The micromechanical devices may be lubricated in wafer form, in which case the lubricant aerosol will lubricate an entire wafer of micromechanical devices at one time. One embodiment produces an aerosol having a mean droplet size of less than 10 microns.Type: GrantFiled: December 31, 2001Date of Patent: November 5, 2002Assignee: Texas Instruments IncorporatedInventor: Simon Joshua Jacobs
