  • Patent number: 9039489
    Abstract: An automated method for reconditioning a plurality of digital discs within a reconditioning apparatus is disclosed. The method comprises holding the digital discs in a load area, and then transferring each of the digital discs from the load area to at least one workstation with a disc transfer mechanism. The method also comprises reconditioning each of the digital discs transferred to the workstation with at least one worktool operable to remove a portion of the protective coating of each of the digital discs without removal of the data underlying the protective coating. The method further comprises transferring each of the digital discs from the workstation to an unload area with the disc transfer mechanism, and then holding the digital discs in the unload area for manual retrieval. Advantageously, the digital discs may be automatically reconditioned within the reconditioning apparatus without manual manipulation of the digital discs during the reconditioning process.

  • Patent number: 9022671
    Abstract: A fiber optic connector fiber stub remover and method for automated fiber stub removal. The device has a top plate with a platen opening, and a platen with a well that carries a polishing film over the well. An air pocket is formed between the polishing film and the well. The platen is positioned with a top surface of the polishing film accessible via the platen opening. A fixture holds connector ends of fiber optic cables with fiber stubs extending therefrom, and a weight biases the fiber stubs into contact with the polishing film. A motor is controlled by a motor control unit to control a ramp up time and final speed of movement of the platen over a timespan. Each connector ends moves independently relative to the polishing film. The air pocket provides shock absorption of the polishing film so that an ideal pressure is exerted on each fiber stub during stub removal.

  • Patent number: 8952496
    Abstract: A wafer surface of a semiconductor wafer to be used as a device active region is mirror-polished, and an outer peripheral portion of the mirror-polished wafer surface is further polished, thereby forming an edge roll-off region between the device active region of the wafer surface and a beveled portion formed at the wafer edge. The edge roll-off region has a specific roll-off shape corresponding to an edge roll-off of the oxide film to be formed in a device fabrication process. Thus, a semiconductor wafer can be provided in which reduction in the thickness of an oxide film on the outer peripheral portion of the wafer in a CMP process can be prevented while maintaining high flatness of the wafer surface.

  • Patent number: 8069566
    Abstract: 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.

  • Publication number: 20110294404
    Abstract: 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.

  • Publication number: 20110269378
    Abstract: 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.

  • Patent number: 7910157
    Abstract: 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.
