  • Sputter source with a target arrangement and a holding device
    Patent number: 5833823
    Abstract: A sputter source and a corresponding target and holding device are provided in which the target is held by form locking arrangements. The target is pushed in an x-direction in the manner of a sliding drawer and is fixed by a releasable lock. A foil, which defines a cooling system on the holding device side, braces the fixed target when the cooling system is acted upon by pressure.
