Problems solved by technology

[0011] However, even cooling devices can only reduce the temperature of the uppermost atomic layer of the target to a limited extent
For example, in ITO sputtering, the maximum possible power density is limited by greater than about 3W / cm 2 The power density of the arc occurring under the limitation of this factor

Embodiment Construction

[0081] FIG. 1 shows a coating device 1 according to the invention in a sectional view. In the coating chamber 2 , an oblong cathode 3 with a length of 1 and a width of b is arranged, and a target 4 is installed on the cathode 3 . In this view, the cathode 3 is located below the target 4 within the page. However, within the scope of the invention, the cathode 3 and the target 4 can also be formed as an integral part, ie the cathode 3 can be formed from the target material 4 itself.

[0082] The cathode 3 is connected to a power source 5 by a connecting cable. Electrical energy can be coupled into the coating system 1 in the form of direct current, alternating current, unipolar pulsed current, bipolar pulsed current or RF (radio frequency) voltage.

[0083] FIG. 2 shows a side view of the coating device 1 as indicated by the coordinate system in its upper left corner. In the coating chamber 2 delimited by walls, a cathode 3 and a target 4 mounted to the cathode 3 are arranged...

Abstract

The magnetron sputtering source for a coating unit (1), comprises a cathode (3), a target (4) assigned to the cathode or integrated into the cathode, means for producing a coating plasma, and a magnet arrangement (7) for producing a magnetic field for the influence of the coating plasma in such a way that a plasma channel (8) is produced over a part of the surface of the target, which provides coating- and / or treatment material. The magnet arrangement and the surface of the target are movably arranged relatively to each other by a drive. which is formed for the reduction of the thermal load of the target surface and an exposure time of the plasma on the surface area.

Description

technical field [0001] The invention relates to a magnetron sputtering source for a coating plant, comprising at least one cathode and at least one target, means for generating a coating plasma, at least one magnet part, said The target is arranged on the cathode or is integrated in the cathode and provides coating material and / or treatment material for coating and / or treatment; the at least one magnet part is used to generate coating-affecting plasma in the following manner The magnetic field of the body in such a way that at least one plasma channel is generated above the local surface of the target; the magnet part and the target are arranged such that they are preferably movable relative to each other by at least one drive. In addition, the present invention also contemplates a sputter coating device comprising at least one treatment or coating chamber and also a magnetron sputtering source. The invention also relates to a treatment method, in particular for coating a sub...
