Abstract: Embodiments of the invention provide a magnetron and a magnetron sputtering device, including an inner magnetic pole and an outer magnetic pole with opposite polarities. Both the inner magnetic pole and the outer magnetic pole comprise multiple spirals. The spirals of the outer magnetic pole surround the spirals of the inner magnetic pole, and a gap exists therebetween. In addition, the gap has different widths in different locations from a spiral center to an edge. Moreover, both the spirals of the outer magnetic pole and the spirals of the inner magnetic pole follow a polar equation: r=a?n+b(cos ?)m+c(tan ?)k+d, 0<=n<=2, 0<=m<=2, c=0 or k=0. Because the gap between the inner magnetic pole and the outer magnetic pole has the different widths in a spiral discrete direction, width sizes of the gap in the different locations can be changed to control magnetic field strength distribution in a plane, thus adjusting uniformity of a membrane thickness.
