  • Patent number: 8444832
    Abstract: The invention relates to the electrical contacting of planar goods 1 in the form of segments in in-line plants for the electrolytic and/or wet chemical treatment of the treatment side 10 of the good by applying electrical external current while keeping the upper contacting side 9 dry and dipping the treatment side 10 into the treatment liquid 11. By use of the known transport systems having upper and lower transport and/or contact means, treatment liquid 11 is transferred from the lower means to the upper ones so that the top side of the good is often inadmissibly wetted and the upper contacts are electroplated, therefore needing to be continuously de-metallized, thus requiring a larger effort. According to the invention, the level is lowered in the region of upper contacts 6. Therefore, the same cannot be wetted, even when no good is present in the region of the contacts 6. This is achieved by means of down pipes 5 which are assigned to each contact 6.

An apparatus in accordance with one embodiment includes a support member configured to releasably carry a microelectronic substrate and first and second electrodes spaced apart from each other and from the microelectronic substrate. A polishing medium is positioned between the electrodes and the support member and has a polishing surface positioned to contact the microelectronic substrate. At least a portion of the first and second electrodes can be recessed from the polishing surface. A liquid, such as an electrolytic liquid, can be provided in the recess, for example, through flow passages in the electrodes and/or the polishing medium. A variable electrical signal is passed from at least one of the electrodes, through the electrolyte and to the microelectronic substrate to remove material from the substrate.

  • Patent number: 7550070
    Abstract: An electrode assembly includes a distribution plate having a plurality of grooves that communicate with openings in an overlying polishing pad layer. The grooves include end openings that allow for draining of process solution, both during processing and subsequent cleaning/rinsing of the pad. Drainage occurs continually during processing, cleaning and rinsing, and so is constricted through the end openings relative to the grooves, to prevent wastage. The end openings are sufficiently large, however, to substantially completely drain fluids from the grooves between steps without delaying robotic motions.

  • Patent number: 7544283
    Abstract: A system for removing a thin metal film is disclosed. The system comprises an inclined metal plate electrode for guiding a downward electrolyte flow, an auxiliary electrode placed on either the upstream or downstream side of the metal plate electrode such that a part of the auxiliary electrode is immersed into the electrolyte, and a power supply for applying a DC voltage to the both electrodes. The system is used to remove a metal thin film on the surface of an insulator by making the electrolyte flowing down the metal plate electrode strike against the metal thin film while the DC voltage is applied to the metal plate electrode and auxiliary electrode.

  • Patent number: 7520966
    Abstract: An electropolishing device for polishing a cylindrical medical device such as a stent includes anodes in the form of rollers arranged to contact an exterior surface of the device. A drive mechanism rotates the anodes periodically during the electropolishing process to change a contact point between the anodes and the medical device. A tilting mechanism can also be used for periodically tilting the anodes during the electropolishing process to allow bubbles to escape from one end of the stent.

  • Patent number: 7485258
    Abstract: A method and device for sterilizing containers in which a plasma treatment is executed through excitation of an electromagnetic oscillation so that the plasma is excited in a vacuum in the vicinity of the container regions to be sterilized. Between arrival and discharge, the container regions to be sterilized are moved closer to the oscillation-generating device in the chamber, with continuous movement of the container and/or of the oscillation-generating device for one or more predetermined time intervals in such a way that a plasma is excited in these regions inside and/or outside the container. The chamber is provided with a transport apparatus inside it, which produces an essentially rotating motion of the container during the transport from the arrival to the discharge in the chamber.

Current flows to the electrode via the shaft to machine the work piece, and the force exerted on the electrode by the work piece is transmitted via the shaft and the isolating element to the sensor converting the force into a signal sent to the control module for raising or lowering the base to maintain contact between the electrode and the work piece. The sensor serves as a detecting mechanism to ensure appropriate contact between the electrode and the work piece.
