Abstract:
1. A method of sputtering comprising: providing a sputtering device for forming a thin film on a substrate, comprising: sputtering in the facing mode so as to coat the substrate with a first layer while controlling a magnetic flux mode of the non-sputtering surfaces to stay in a magnetron mode by controlling the other pole groups to form magnetic flux-lines on the non-sputtering surfaces, wherein the sputtering in the facing mode is performed by the magnetic flux-line pattern control means controlling movement of the first and second movable pole elements in the first directions to adjust a polarity between the first and second targets to form the magnetic flux-lines and thereby forming the first layer as an initial growth layer; and subsequent to the sputtering in the facing mode, sputtering in the mixed mode so as to coat the substrate with a second layer while controlling the magnetic flux mode of the non-sputtering surfaces to stay in the magnetron mode by controlling the other pole groups to form the magnetic flux-lines on the non-sputtering surfaces, wherein sputtering in the mixed mode is performed by the magnetic flux-line pattern control means controlling movement of the first and second movable pole elements in the second directions to form the curved magnetic flux-lines formed on the first and second targets while the magnetic flux-lines are also formed between the first and second targets.
