  • Patent number: 7276711
    Abstract: A beam space-charge compensation device is applied to an angular energy filter provided in an ion beam processing system that performs processing by irradiating onto a wafer with an ion beam. The beam space-charge compensation device comprises a plasma shower provided in a beam-guiding chamber of the angular energy filter. The plasma shower comprises an arc chamber having a filament for generating thermo-electrons for plasma. The arc chamber comprises an extraction hole for extracting the thermo-electrons. The plasma shower is arranged such that the extraction hole is located on lines of magnetic force, perpendicular to an ion beam advancing direction, of the magnetic field and that a center axis of the filament and a center axis of said extraction hole coincide with the lines of magnetic force, perpendicular to the ion beam advancing direction, of the magnetic field.

  • Publication number: 20060166744
    Abstract: Each of game data storage parts (40), in which, while a replication of game data is created, and an item can be used on the basis of different game data, it is possible to prevent the item from increasing by the replication, stores original item data relating to an original item and replica item data relating to a replica item. Besides, a replication part (54) stores game data into a replication target on the basis of game data stored in a replication source so that a sum of the number of original items relating to the original item data stored in the game data storage part (40) of the replication source and the number of replica items relating to the replica item data stored in the game data storage part (40) becomes the number of replica items relating to the replica item data stored in the game data storage part (40) of the replication target. At this time, link data to correlate the replication target with the replication source is also stored.

  • Publication number: 20060113467
    Abstract: In an irradiation system with an ion beam/charged particle beam having an energy filter, the energy filter is formed by deflection electrodes and a deflection magnet which can be switchingly used. The deflection magnet has a general window-frame shape and is formed with a hollow portion at its center. The deflection electrodes are installed, along with suppression electrodes, in a vacuum chamber arranged in the hollow portion of the deflection magnet. The deflection electrodes are installed with respect to the deflection magnet such that a deflection trajectory of a beam caused by a magnetic field and a deflection trajectory of a beam caused by an electric field overlap each other. Since the deflection electrodes and the deflection magnet can be switchingly used, the system can deal with a wider range of beam conditions and thus is widely usable.

  • Publication number: 20060113492
    Abstract: A charge compensation device according to this invention is for suppressing charging of a wafer when the wafer is irradiated with a beam from a beam generation source unit. The charge compensation device comprises at least one first arc chamber having at least one first extraction hole and a second arc chamber having at least one second extraction hole faced on the reciprocal swinging beam of the predetermined scan range. A first arc voltage is applied to the first arc chamber to generate first plasma in the first arc chamber. The generated first plasma is extracted from the first arc chamber and introduced into the second arc chamber. Second plasma is produced in the second arc chamber, and second extracted plasma from the second arc chamber forms a plasma bridge between the second extraction hole and the reciprocal swinging beam.
