Patent number: 6458696Abstract: The specification describes interconnection techniques for interconnecting large arrays of micromechanical devices on a silicon platform. Interconnections are routed through vias extending through the thickness of the substrate. The vias are formed by etching holes through the silicon wafer, depositing an insulating layer on the sidewalls of the holes, depositing a barrier layer on the insulating layer, electrolytically depositing a metal selected from the group consisting of copper and nickel to form via plugs in the holes, and depositing another barrier layer over the via plugs. It is found that electrolytic deposition will successfully plug the holes even when the aspect ratio of the through holes is greater than four and the hole diameter less than 100 microns.Type: GrantFiled: April 11, 2001Date of Patent: October 1, 2002Assignee: Agere Systems Guardian CorpInventor: Michal Edith Gross

Publication number: 20020100695Abstract: A method and apparatus for anodizing a component. The component is placed in a container having first and second seal members that seal an annular surface of the component to be anodized. The first and second seal members, the annular surface of the component, and an inner surface of the container form a reaction chamber that holds a reaction medium therein. The reaction medium is supplied to the reaction chamber through a supply passage formed in the container. The reaction medium is drained from the reaction chamber through a drain passage formed in the container.Type: ApplicationFiled: January 15, 2002Publication date: August 1, 2002Applicant: UNISIA JECS CORPORATIONInventors: Masato Sasaki, Yuzuru Morioka, Sachiko Sugita, Masazumi Ishikawa

Patent number: 6413440Abstract: In a process for manufacturing an electrode (1) on a substrate (2) using a conventional structuring process, an electrically conducting surface structure is created which has at least one tip (3) or edge (4). In the area of the tip (3) or edge (4), an electrode layer (5) is galvanized onto the substrate (2) and/or applied by electrostatic powder coating. Then, a surface area of the substrate (2), which surrounds the electrode layer (5) located on the tip (3) or edge (4), is converted into an insulating layer (8) by a chemical reaction. The electrode layer (5) can also be applied in a manner where, in the area of the tip (3) or edge (4), a chemical is released, which upon irradiation by electromagnetic and/or particle radiation, precipitates an electrically conducting material. This chemical is then impinged in the area of the tip (3) or edge (4) with optical radiation.Type: GrantFiled: July 13, 1999Date of Patent: July 2, 2002Assignee: Micronas GmbHInventor: Günter Igel

Patent number: 6372110Abstract: The electrochemical processing of a component such as an injection nozzle, must be calibrated in order to compare the throughput of the nozzle to a standard nozzle. Both throughput rates are determine at the same high pressure which is far above 100 bar. As a throughput medium, electrolyte is used in an ecm unit. From this a sufficient quantity is delivered into a temporarily pressure chamber in which another fluid has been supplied by a high pressure pump. A predetermined high pressure is built up which by way of a highly accurate control valve is maintained during the calibration procedure.Type: GrantFiled: March 23, 2000Date of Patent: April 16, 2002Inventor: Fritz-Herbert Frembgen
