Patent number: 10837928Abstract: Reaction vessels which allow visualization while speeding vaporization or other reactions. In one illustrative embodiment, a reaction vessel may have sidewalls formed from a transparent material such as a clear quartz glass having relatively smooth surface and relatively low thermal transfer properties while allowing for visualization into the vessel. The vessel floor may be formed from a porous textured opaque quartz glass bottom. Liquids in the vessel will more readily react due to the numerous pores on the surface of the material of the bottom which serve as active nucleation sites during a chemical reaction process. Additionally, an unexpectedly higher rate of thermal diffusivity into the vessel interior may further increase reaction speeds. Methods of conducting and analyzing reactions using such vessels are further included in the present disclosure.Type: GrantFiled: July 2, 2018Date of Patent: November 17, 2020Inventor: Jason Locke Barney

It is ensured that insulation is stripped from an end 14 of the stranded wire. An electrically conductive lead-frame connection structure 16 is associated with the lead-frame body. The end 14 of the stranded wire is inserted into the lead-frame connection structure 16 so that the lead-frame connection structure substantially surrounds the wire end. Solder flux is injected so as to be substantially about a portion of the end of the stranded wire. The lead-frame connection structure is placed in contact with a bottom resistance welding electrode 18 or a top resistance welding electrode 20.Type: GrantFiled: October 3, 2006Date of Patent: December 16, 2008Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 7303967Abstract: Disclosed is a method for fabricating a transistor of a semiconductor device, the method comprising the steps of: providing a semiconductor; forming a gate electrode; performing a low-density ion implantation process with respect to the substrate, thereby forming an LDD ion implantation layer; forming an insulation spacer on a sidewall of the gate electrode; forming a diffusion barrier; performing a high-density ion implantation process with respect to the substrate, thereby forming a source/drain; performing a first thermal treatment process with respect to a resultant structure, so as to activate impurities in the source/drain, and simultaneously causing a diffusion velocity of the impurities in the source/drain to be reduced by the diffusion barrier; and forming a salicide layer.Type: GrantFiled: June 23, 2004Date of Patent: December 4, 2007Assignee: Hynix Semiconductor Inc.Inventor: Seung Hoon Sa

Patent number: 7268037Abstract: A process for modifying sections of a semiconductor includes covering the sections to remain free of doping with a metal oxide, e.g., aluminum oxide. Then, the semiconductor is doped, for example, from the gas phase, in those sections that are not covered by the aluminum oxide. Finally, the aluminum oxide is selectively removed again, for example using hot phosphoric acid. Sections of the semiconductor surface which are formed from silicon, silicon oxide or silicon nitride remain in place on the wafer.Type: GrantFiled: January 24, 2005Date of Patent: September 11, 2007Assignee: Infineon Technologies, AGInventors: Stefan Jakschik, Thomas Hecht, Uwe Schröder, Matthias Goldbach

Patent number: 7101812Abstract: A process for forming and/or modifying dielectric films on semiconductor substrates is disclosed. According to the present invention, a semiconductor wafer is exposed to a process gas containing a reactive component. The temperature to which the semiconductor wafer is heated and the partial pressure of the reactive component are selected so that, sometime during the process, diffusion of the reactive components occurs through the dielectric film to the film/semiconductor substrate interface. Further, diffusion also occurs of semiconductor atoms through the dielectric film to an exterior surface of the film. The process of the present invention has been found well suited to forming and/or modifying very thin dielectric films, such as films having a thickness of less than 8 nm.Type: GrantFiled: March 10, 2003Date of Patent: September 5, 2006Assignee: Mattson Technology, Inc.Inventors: Ignaz Eisele, Alexandra Ludsteck, Jörg Schulze, Zsolt Nenyei, Waltraud Dietl, Georg Roters
