  • Publication number: 20040050689
    Abstract: The invention relates to a vacuum sputter method for producing dielectric layers. The aim of said invention is to obtain a good distribution of said layers over the substrate to be coated, in a reproducible manner over the entire service life of the target (9) to be sputter-coated. To achieve this, the thickness of the dielectric target (9), which is sputter-coated using a high frequency, is profiled. Said profiles are chosen in such a way that the target thickness is greater in the area of increased erosion rates and/or smaller in the area of lower erosion rates.

  • Publication number: 20030075434
    Abstract: To generate an especially good heat transfer between a seating face of a storage plate support and a storage plate, during coating with a sputter source in a vacuum installation, the seating face of the storage plate support is slightly annularly convexly arched and the storage plate is clamped in the center as well as on its outer margin by a center mask and an outer mask against the arched seating face. Hereby an especially good heat transfer is attained with very low arching d, whereby the storage plate is treated gently and simultaneously, during the coating process, no layer thickness distribution problems occur through arching that is too large.

  • Patent number: 6453543
    Abstract: Disclosed is a workpiece conveyor and delivery device for a vacuum processing plant. Workpieces are delivered from one device to another, both devices being located opposite each other and moving in relation to each other. A controllable magnet arrangement is provided on one of the devices. A moveable armature element acts as a holding device for the workpiece on one of the two devices which move in relation to each other, namely the device provided with the magnet arrangement. Magnet arrangement is driven to activate the holding device which can be deactivated for delivery of workpiece.

  • Patent number: 5882171
    Abstract: A transport and transfer arrangement for a workpiece in a vacuum treatment apparatus has a first transport member with at least one first workpiece holder and a second transport member with at least one second workpiece holder. The first and second transport members are movable relative to each other and in a position in which said one first and said one second workpiece holders are in a spaced face-to-face position. At least one transfer armature member is made of magnetic material. The first and second workpiece holders are part of controllable magnetic arrangement which generates in the spaced face-to-face position and between the workpiece holders, a magnetic force controllable to act in either direction and magnetically driving said transfer armature member controllably in a first direction from the first workpiece holder towards and onto said second workpiece holder and vice versa in a second direction as the workpiece holders are face to face.
