Patent number: 8069566Abstract: An operating method improves the running behavior of gearwheels negatively noticed upon gearwheel testing and is performed by a burnishing device. The gearwheels that were rejected from the production process may be optimized rapidly and in a targeted way so that they may be returned back into the production process. The tooth flanks of a gearwheel to be machined are, in a first method step, mechanically freed of particles adhering to the surfaces of the tooth flanks or slight protrusions protruding therefrom using a first gearwheel machining tool having a machining wheel coated with an abrasive agent. Subsequently, in a second method step in a second gearwheel machining tool known as a burnishing machine, the gearwheel is chucked between gearwheel-shaped rolling tools, the so-called burnishing wheels, and rolled without material abrasion.Type: GrantFiled: March 21, 2008Date of Patent: December 6, 2011Inventor: Wolfgang Linnenbrink

Publication number: 20110294404Abstract: A method and system for tunable removal rates and selectivity of materials during chemical-mechanical polishing using a chemical slurry or solution with increased dissolved oxygen content. The slurry can optionally include additives to improve removal rate and/or selectivity. Further selectivity can be obtained by varying the concentration and type of abrasives in the slurry, using lower operating pressure, using different pads, or using other additives in the dispersion at specific pH values.Type: ApplicationFiled: May 31, 2011Publication date: December 1, 2011Applicant: CLARKSON UNIVERSITYInventors: P.R. Veera Dandu, Naresh K. Penta, Babu V. Suryadevara, Uma Rames Krishna Lagudu

Publication number: 20110269378Abstract: The invention relates to a chemical mechanical polishing system, comprising: at least one polishing platens rotatably installed with a platen pad mounted on its upper surface; a guide rail disposed along a predetermined path; a substrate carrier unit including a rotary union to downwardly press a substrate during a polishing process, the substrate carrier unit moving along the guide rail with loading the substrate; and a docking unit installed to be docked to the substrate carrier unit so as to supply air pressure to the rotary union which downwardly presses the substrate held by the substrate carrier unit, when the substrate carrier unit is positioned over the polishing platen, whereby even though the substrate carrier unit is moved to consecutively polish the substrate on the plural polishing platens, it substantially removes a phenomenon of the twisting of air pressure supply tubes due to the movement of the substrate carrier unit.Type: ApplicationFiled: April 27, 2011Publication date: November 3, 2011Inventors: Jae Phil Boo, Dong Soo Kim, Keon Sik Seo, Chan Woon Jeon, Jun Ho Ban, Ja Cheul Goo

Patent number: 7910157Abstract: In the present invention, an insulating material is applied onto a substrate in a coating treatment unit to form a coating insulating film. The substrate is heated in the heating processing unit, whereby the coating insulating film is hardened partway. A brush is then pressed against the front surface of the coating insulating film in a planarization unit and moved along the front surface of the coating insulating film, thereby planarizing the coating insulating film. The substrate is then heated to completely harden the coating insulating film. According to the present invention, the coating film can be planarized without using the CMP technology.Type: GrantFiled: December 15, 2006Date of Patent: March 22, 2011Assignee: Tokyo Electron LimitedInventors: Shouichi Terada, Tsuyoshi Mizuno, Takeshi Uehara
