Description

technical field [0001] The invention relates to a coating device and a coating method, in particular to a device and a method for coating equipment to be coated by magnetron sputtering under vacuum conditions. Background technique [0002] Magnetron sputtering (magnetron-sputtering) is a "high-speed low-temperature sputtering technology" developed rapidly in the 1970s. Magnetron sputtering is the formation of an orthogonal electromagnetic field above the surface of the cathode target. When the secondary electrons generated by sputtering are accelerated into high-energy electrons in the cathode drop region, they do not fly directly to the anode, but oscillate back and forth in an approximately cycloidal motion under the action of an orthogonal electromagnetic field. High-energy electrons continuously collide with gas molecules and transfer energy to them, ionizing them and becoming low-energy electrons themselves. These low-energy electrons eventually drift along the magnet...
