Abstract
The primary goal of this study is to optimize the dynamic axial magnetic field distribution in magnetron sputtering system, guiding the target ions to project directly to the substrate. A group of electromagnetic coils were set up to generate an auxiliary axial magnetic field. The configuration of axial magnetic field in different electrifying modes on coils were simulated using numerical integration. Based on the general theoretical results, this paper proposed an optimization of coil arrangement and electrifying modes for a C-shape direct current(DC) magnetron. A 3D model of the coils was set up and the finite element analysis results verified the accuracy of theoretical results. Consequently, this study proposed an arrangement and electrified scheme of electromagnetic coils to provide a dynamic auxiliary axial magnetic field, which could match with the shape and movement of the primary magnetron.
