Provided are an ionized PVD device capable of performing film formation having excellent vertical growth, and more particularly an ionized PVD device having a comparatively simple structure in which a rate of a metal film formed by neutral metal atoms can be reduced in a contact hole of a semiconductor substrate to perform film formation having excellent bottom coverage, and a method for manufacturing a semiconductor device using the ionized PVD device. Air-core coils are provided on an outside of a vacuum chamber concentrically with a central axis of the vacuum chamber and an extension axis of the central axis. The air-core coils are electromagnets for forming an S-shaped magnetic field in the vacuum chamber almost along a contour shape thereof. The air-core coils are provided so as to form the magnetic field in a straight portion in the vicinity of both ends of the vacuum chamber, and the air-core coils are provided so as to form the magnetic field in a bent portion of the vacuum chamber.
