A physical vapor deposition reactor includes a vacuum chamber including a sidewall, a ceiling and a wafer support pedestal near a floor of the chamber, a vacuum pump coupled to the chamber, a process gas inlet coupled to the chamber and a process gas source coupled to the process gas inlet. A metal sputter target is located at the ceiling and a high voltage D.C. source coupled to the sputter target. An RF plasma source power generator is coupled to the metal sputter target and has a frequency suitable for exciting kinetic electrons. Preferably, the wafer support pedestal comprises an electrostatic chuck and an RF plasma bias power generator is coupled to the wafer support pedestal having a frequency suitable for coupling energy to plasma ions. Preferably, a solid metal RF feed rod having a diameter in excess of about 0.5 inches engages the metal sputter target, the RF (feed rod) extending axially above the target through the ceiling and being coupled to the RF plasma source power generator.
