Magnetron sputtering apparatus

特許 権利維持 A sputtering method includes disposing a plurality of thin and long deposition regions such that the thin and long deposition regions each cross in a first direction a circular reference region having a diameter equal to that of a semiconductor wafer, and are arranged at predetermined intervals in a second direction perpendicular to the first direction; disposing one of the plurality of thin and long deposition regions such that one side of sides thereof extending in the first direction passes through a substantial center of the circular reference region.
