Abstract
A PVD method and a PVD apparatus use a rotating magnetic field in order to increase the yield. The magnetic field is provided such that it essentially vanishes, at least in a time average, outside a rotation axis of the magnetic field in sectors of the target region of the PVD apparatus. In this manner the PVD method and the PVD apparatus achieve a uniform coating.
