  • Patent number: 11094515
    Abstract: A sputtering apparatus has a vacuum chamber capable of arranging a target material and a substrate therein so as to face each other, a DC power supply capable of electrically being connected to the target material, and a pulsing unit pulsing electric current flowing in the target material from the DC power supply, in which plasma is generated in the vacuum chamber to form a thin film on the substrate, including an ammeter measuring electric current flowing in the pulsing unit from the DC power supply, a power supply controller performing feedback control of the DC power supply so that a current value measured by the ammeter becomes a prescribed value and a pulse controller indicating a pulse cycle shifted from a control cycle of the DC power supply by the power supply controller to the pulsing unit.
    Type: Grant
