  • Patent number: 8608918
    Abstract: A magnet structure and the like are provided, which can reduce the labor required to make a magnet design for producing a tunnel-shaped leakage magnetic field for plasma confinement in a well-balanced manner over an obverse surface of a target, based on a quadridirectional magnetic field produced by magnetic interaction between plural magnets.
    Type: Grant
    Filed: August 23, 2006

  • Publication number: 20090229977
    Abstract: Provided are a magnet structure and the like capable of changing a magnetic force line distribution on a surface of a target to thereby achieve wide erosion of a target, using a simple drive mechanism. A magnet structure (110) comprises a main magnet (10, 13) disposed at a reverse surface (20B) side of a target (20) to produce a main magnetic force line reaching an obverse surface (20A) of the target, an adjustment magnet (11) disposed at the reverse surface (20B) side of the target (20) to produce an adjustment magnetic force line for changing a magnetic flux density distribution produced by the main magnetic force line, a magnetic path (21A, 21B, 24) of the adjustment magnetic force line which is disposed at the reverse surface (20B) side of the target 20, and a magnetic field adjustment means (12, 14) configured to be able to change strength of the adjustment magnetic force line passing through inside of the magnetic path (21A, 21B, 24).

  • Publication number: 20080289957
    Abstract: A vacuum film forming apparatus is provided that is intended to use a portion of its cylindrical member as a target and moreover have an additional function of plasma polymerization using the cylindrical member. A vacuum film forming apparatus (100) is provided with an electrically conductive vacuum chamber (13) having an interior space, a frame member (15) having a plurality of curved members (31, 32) each curved in a sector shape and arranged in the interior space (10) so as to form a substantially cylindrical shape, and a magnetic field forming device (33) disposed in an interior surrounded by the frame member (15) and configured to form a magnetic field along the circumference of the frame member (15). At least one of the curved members (15, 16) is a target used for sputtering, and a region of the frame member (15) other than the target is used for plasma polymerization.

  • Publication number: 20070277732
    Abstract: A film forming apparatus which can perform a film forming process to a base material while the base material is being mounted on a die for a molding process. The film forming apparatus is provided with a cylinder-shaped frame body (1h) having one end closed with a bottom part and the other end opened, a target (1a) arranged on an inner plane of the bottom part, and a port (3b) formed to penetrate a wall part of the frame body (1h).
