Physical vapor deposition apparatus

A physical vapor deposition (PVD) apparatus includes: a vacuum chamber; a pedestal arranged in the vacuum chamber and configured to support a substrate; a target arranged on the vacuum chamber and including a deposition material; a shield arranged on an inner sidewall of the vacuum chamber to protect the vacuum chamber from the deposition material; a target power supply applying a target voltage to the target to generate plasma in the vacuum chamber; and a magnet configured to induce the plasma to the target; and a magnetic field formation line connected with the target power supply, wherein the magnetic field formation line surrounds the shield symmetrically with respect to a center of the shield to form a magnetic field in the vacuum chamber.
