Beschreibung
Zusammenfassung:	A plasma vapor deposition (PVD) chamber used for depositing material includes an apparatus for influencing ion trajectories during deposition on a substrate. The apparatus includes at least one annular support assembly configured to be externally attached to and positioned below a substrate support pedestal and a magnetic field generator affixed to the annular support assembly and configured to radiate magnetic fields on a top surface of the substrate. The magnetic field generator may include a plurality of symmetrically spaced discrete permanent magnets or may use one or more electromagnets to generate the magnetic fields.
