There is provided a sputter device in which a conductive target having a planar and circular shape is disposed so as to face a workpiece substrate mounted on a mounting part located within a vacuum chamber, includes: a direct current power supply configured to apply a negative direct current voltage to the target; an opposing electrode installed at the opposite side of the workpiece substrate from the target so as to face the target; and a target high-frequency power supply connected to the target and configured to supply high-frequency power to the target in order to generate a high-frequency electric field between the opposing electrode and the target, wherein the distance between the target and the workpiece substrate during a sputtering process being 30 mm or less. |
