    摘要: A method of depositing a layer on a substrate includes applying a first magnetic field to a cathode target, electrically coupling the cathode target to a first high power pulse resonance alternating current (AC) power supply, positioning an additional cylindrical cathode target electrode around the cathode, applying a second magnetic field to the additional cylindrical cathode target electrode, electrically coupling the additional cylindrical cathode target electrode to a second high power pulse resonance AC power supply, generating magnetic coupling between the cathode target and an anode, providing a feed gas, and selecting a time shift between negative voltage peaks associated with AC voltage waveforms generated by the first high power pulse resonance AC power supply and the second high power pulse resonance AC power supply. An apparatus includes a vacuum chamber, cathode target magnet assembly, first high power pulse resonance AC power supply, additional electrode, additional electrode magnet assembly, second high power pulse resonance AC power supply, and feed gas.

    摘要: A vacuum treatment apparatus includes a vacuum treatment recipient with a circular opening between an inside and exterior of the recipient. The recipient houses a turntable, which defines a plane (P) along its table surface, is drivingly rotatable around a central axis perpendicular to plane (P), and exhibits a plurality of circular substrates supports. The opening is arranged such that during a turn of the turntable the area of each of the substrate supports and the opening are fully aligned and completely face each other. The vacuum treatment apparatus also includes a PVD deposition source attached to the opening. The PVD source has a a circular material target and a static magnet arrangement. The magnet arrangement is arranged in a plane (M) in parallel to plane (P) and is not rotationally symmetric around a central axis running centrally through the magnet arrangement and being perpendicular to the plane (M).

    摘要: A cathode assembly is provided in which, while preventing the occurrence of abnormal electric discharging between a projected portion of a backing plate and a side surface of a target, particles can be prevented from being generated. The cathode assembly for a sputtering apparatus of this invention has: a target made of an insulating material; a backing plate bonded to one surface of the target; and, where such a side of the backing plate as is on the side of the target is defined as a lower side, an annular shield plate disposed to lie opposite to the lower side of that projected portion of the backing plate which is projected outward beyond an outer peripheral end of the target. The cathode assembly has a bonding portion arranged to be protruded relative to the projected portion. An inner peripheral edge portion of the shield plate is positioned in a clearance between that extended portion of the target which is extended outward beyond the bonding portion in a state in which the target is kept bonded to the bonding portion, and the projected portion of the backing plate.
