摘要： PURPOSE:To reduce the quantity of permanent magnets and the manufacturing cost by arranging a magnetic metal on the inside of a permanent magnet on the reverse side of a target in a magnetron sputtering devise and bringing one end of the magnetic metal into contact with a permanent magnet to be magnetized. CONSTITUTION:When a permanent magnet for the center part and a permanent magnet for the peripheral part are arranged on the reverse side of target 2 as a film forming material to a base 3 in a magnetron sputtering device, Fe or other magnetic metal 6 on behalf of the permanent magnet for the center part is arranged, the magnetic metal 6 is magnetized by bringing its one end into contact with the permanent magnet 5 for the external peripheral part and at the same time, the part facing the target 2 of the magnetic metal 6 is operated as a magnetic pole. A permanent magnet of past complicated form composed of a permanent magnet for the peripheral part and a permanent magnet for the central part is not required, part of a permanent magnet on the rear of a target for a magnetron sputtering is substituted by a magnetic metal and, accordingly, the structure of permanent magnet is simplified and the cost of the permanent magnet also can be drastically reduced.

摘要： PURPOSE:To suppress the high-frequency intrusion into ion extracting power supplies and stabilize the operation as an ion source by inserting a high-frequency attenuator reducing high-frequency propagation between an ion extracting device and both pole terminals of the power supplies feeding the voltage to the ion extracting device. CONSTITUTION:An ion extracting device is constituted of an extracting electrode 2 applied with the positive voltage with respect to the container potential of a machining chamber 4 and an accelerating electrode 3 applied with the negative voltage with respect to the container potential of the machining chamber 4, and the electric field for accelerating positive ions from a plasma chamber 1 toward the machining chamber 4 is formed between the electrodes 2 and 3. DC stabilized power supplied 15, 15' are connected to individual electrodes via high-frequency blocking filters 14, 14' and a filter 14'' between the container of the machining chamber 4 and the DC power supplies. In addition, if high-frequency blocking filters 17, 17' and insulating transformers 15, 15' are inserted in commercial-frequency power supplies 18, 18' for the DC stabilized power supplies, the high-frequency current intrusion into grounding cables 19, 19' of the commercial-frequency power supplies is blocked.

摘要： PURPOSE:To eliminate the attraction force by a permanent magnet in the stage of exchanging a target by respectively independently attaching and detaching the permanent magnet and target in the stage of assembling a target electrode. CONSTITUTION:The target 5 is assembled and installed and thereafter the permanent magnet 6 is assembled in the prescribed position in the stage of assembling the target electrode 4. The electrode 4 is removed from a vacuum vessel 1 and is fixed onto a hydraulic operating table 16 in the stage of exchanging the target 5. a supporting plate 8 is removed and a shaft 18 is forced upward to release the target 5 and the magnet 6. The target 5 is held fixed to a target electrode container 9 by a hermetic means but the attraction force of the magnet 6 does not act at this point of the time and therefore the target can be easily exchanged. The assembly is executed reverse therefrom. The external force by the magnet 6 does not act during the exchange of the target 5 according to the above-mentioned mechanism and therefore the constitution of the target 5 is made simple.
