  • Publication number: 20080296165
    Abstract: A plating method and apparatus for a substrate fills a metal, e.g., copper, into a fine interconnection pattern formed in a semiconductor substrate. The apparatus has a substrate holding portion 36 horizontally holding and rotating a substrate with its surface to be plated facing upward. A seal material 90 contacts a peripheral edge portion of the surface, sealing the portion in a watertight manner. A cathode electrode 88 passes an electric current upon contact with the substrate. A cathode portion 38 rotates integrally with the substrate holding portion 36. An electrode arm portion 30 is above the cathode portion 38 and movable horizontally and vertically and has an anode 98 face-down. Plating liquid is poured into a space between the surface to be plated and the anode 98 brought close to the surface to be plated. Thus, plating treatment and treatments incidental thereto can be performed by a single unit.

  • Patent number: 7453046
    Abstract: A fixing member is spaced from a head actuator by a predetermined distance. A flexible printed circuit board extends at least from the head actuator to the fixing member. The flexible printed circuit board is superposed on the surface of the fixing member. A viscoelastic layer and a protecting layer are overlaid on the surface of the flexible printed circuit board. A clip clips all the fixing member, the flexible printed circuit board, the viscoelastic layer and the protecting layer together. When a head slider is positioned, the head actuator changes its attitude relative to a recording disk. The inertial force based on the rotation causes the first flexible printed circuit board to vibrate when the actuator block stops rotating. The viscoelastic layer serves to absorb this residual vibration of the first flexible printed circuit board. Vibration of the flexible printed circuit board can be suppressed.

  • Patent number: 7414815
    Abstract: A magnetic disk device comprises a magnetic disk in which a data zone is formed. An actuator has a voice coil and a head slider carrying a magnetic head, the actuator being swung to move the magnetic head over the disk between an innermost position of the data zone and an outermost position of the data zone. A magnet has a magnetization center and is opposed to the voice coil so that a voice coil motor which swings the actuator is formed, the magnet having a north pole and a south pole confronting each other via the magnetization center. The magnetic disk device is provided so that a deviation of a center of the voice coil from the magnetization center when the magnetic head is in the innermost position of the data zone is substantially equal to a deviation of the center of the voice coil from the magnetization center when the magnetic head is in the outermost position of the data zone.
