Description

technical field [0001] The invention relates to a rotating magnetic field planar target magnetron sputtering device, which belongs to the technical field of electronic machinery, and in particular relates to a magnetron sputtering coating device in the electronic thin film preparation technology. Background technique: [0002] As a coating device, magnetron sputtering device is being widely used in the preparation of electronic thin films. The magnetron sputtering thin film preparation device in the existing electronic thin film preparation technology can realize the preparation of metals, non-metallic substances and compounds, etc., but there are low target utilization rates, small sputtered films, and poor uniformity. Disadvantages such as low sputtering rate. [0003] The principle of magnetron sputtering: Under the action of an electric field, electrons collide with Ar atoms during their flight to the substrate, causing them to ionize out of Ar + and a new electron, th...
