Abstract

The invention provides a megnetron sputtering cathode system which comprises an annular target material and a magnetic assembly that is rotatably arranged in the annular target material. The magneticfield line of the magnetic assembly penetrates through the annular target material. The magnetic assembly moves relative to the target material. The magnetic field line change which is formed by the magnetic assembly on the surface of the target material prevents a boundary effect of the target material through function of a fixed magnetic field, reduces partial loss of the target material and improves film plating quality.
