Abstract

The invention belongs to the technical field of production equipment for magneto-controlled sputter coating and particularly relates to a middle and low-vacuum magnetron sputtering target cathode. The magnetron sputtering target cathode comprises a cathode shell (1), a target (2), an outer magnet (3), an inner magnet (4), a base (5) and a cooling channel (6), wherein the cathode shell (1) is in a shape of a hollow cylinder, the outer magnet (3) is embedded in the side wall of the cylinder, the inner magnet (4) is arranged in the center of the cathode shell (1), the cooling channel (6) is arranged between the inner magnet (4) and the cathode shell (1), the target (2) is arranged on the upper surface of the cathode shell (1), the base (5) is arranged on the lower surface of the cathode shell (1), and the height difference between the inner magnet (4) and the outer magnet (3) is 1-10mm. The utilization rate of the target is increased by adopting the method of optimizing the structure of the magnetron sputtering target cathode. The magnetron sputtering target cathode provided by the invention is simple in structure, is strong in operability and is reliable in performance.

Description

technical field [0001] The invention belongs to the technical field of magnetron sputtering coating production equipment, and in particular relates to a magnetron sputtering target cathode used in medium and low vacuum. The utilization rate of the target is improved by optimizing the structure of the magnetron sputtering target cathode. Background technique [0002] Magnetron sputtering is under the action of the static magnetic field generated by the permanent magnet. When the cathode is working, due to the limitation of the glow discharge area, the ionization degree of the area with the largest parallel component of the magnetic field on the target surface is enhanced, and the ionized process gas ions are limited in a narrow space. On the circular "runway", only a part of the target surface is sputtered intensively. After sputtering, a ring-shaped "racetrack"-shaped pit is left on the target surface, and a narrow etching area is formed on the corresponding target surface. ...
