Patent number: 6814855Abstract: A method and apparatus for measuring a target constituent of an electroplating solution using an electroanalytical technique is set forth. In accordance with the method, at least two electrodes are employed to execute the electroanalytical technique. Gasses that are trapped or generated at the surface of one or both of the electrodes of the pair are reduced and/or removed by directing a flow of solution toward the electrode surface. This flow of solution against the electrode surface acts to automatically flush the generated gasses (typically in the form of small bubbles) from the electrode surface and generally eliminates the need for manual purging by an operator. Elimination of these gasses reduces or eliminates variability in the open circuit potential, and concomitant noise that would otherwise occur in the electroanalytical measurements.Type: GrantFiled: August 16, 2001Date of Patent: November 9, 2004Assignee: Semitool, Inc.Inventors: Lyndon W.

Patent number: 6814897Abstract: The invention relates to methods for making mold tools. More particularly, the mold tools are used for molding a resin substrate which has fine pits, i.e., concavities and protuberances. The invention also pertains to a method for manufacturing a resin substrate. Such resin substrates may be used as an optical disk, a magnetic disk, a hard disk, etc., for recording data. According to a preferred embodiment of the invention, a first metallic (Ni) mold tool (father) is made which is a duplicate of a master substrate, then a resin mold tool (mother) is made which is a duplicate of the first metallic mold tool and finally a second metallic (Ni) mold tool (son) is made which is a duplicate of the resin mold tool. Both the father and son may be referred to a “stamper”. The invention also relates to methods of manufacturing a mold tool for molding the base of an optical disk having at least one signal recording region and at least one non-signal recording region.Type: GrantFiled: December 5, 2000Date of Patent: November 9, 2004Assignee: Discovision AssociatesInventor: Seiji Morita

Patent number: 6814898Abstract: A method of performing imprint lithography of a surface of a workpiece including a substrate, wherein a stamper/imprinter comprised of a material having thermal expansion characteristics different from the material of said substrate is utilized for embossing a desired pattern in said workpiece surface, the method comprising conducting the embossing at room temperature in order to avoid deleterious effects arising from differences in thermal expansion/contraction characteristics between the stamper/imprinter and the workpiece which occur during conventional imprinting at elevated temperatures. Embodiments of the invention include forming servo patterns in disk-shaped substrates utilized in the manufacture of hard disk magnetic recording media.Type: GrantFiled: October 1, 2001Date of Patent: November 9, 2004Assignee: Seagate Technology LLCInventors: Neil Deeman, Gennady Gauzner

Patent number: 6814900Abstract: A method for molding an optical attenuator having a unitary lens portion and supporting portion includes the steps of: providing a mold having cavity and core elements which together define a space in which the optical attenuator can be molded including a movable core pin having a proximal end defining a surface of the lens portion, and a core pin motor coupled to the core pin for adjusting the thickness of the lens portion; injecting a suitable polymer into the space to form the optical attenuator; separating the cavity and core elements to extract the optical attenuator from the mold; optically measuring the thickness of the lens portion; and providing a signal indicative of the thickness of the lens to a controller having an output coupled to the core pin motor, the controller providing a signal to the core pin motor specifying any movement necessary to retain the thickness of the lens portion within a desired range before repeating the injecting step.Type: GrantFiled: October 1, 2002Date of Patent: November 9, 2004Assignee: L.L. Culmat, LPInventors: Ricky W. Tumlin, J. Larry Underwood
