Abstract:
A plasma reactor for sputtering metals and dielectric films, the reactor comprising:a plasma reactor chamber adapted for receiving a processing gas in the chamber and adapted for connection to an evacuation source;a direct current (DC) driven magnetron positioned within the reactor chamber, the magnetron being adapted to hold a sputtering target;a DC signal source connected to the magnetron;a movable substrate supporting pedestal adapted to hold a substrate, positioned within the reactor chamber and movable so as to place the substrate sufficiently proximate to the sputtering target to enable deposition of sputter products onto the substrate;a first radio frequency signal source connected to the substrate pedestal via a first radio frequency match box having a phase shifting adjustment means;a radio frequency antenna positioned about the chamber, the antenna having a substrate end;a second radio frequency signal source connected to the radio frequency antenna via a second radio frequency match box;an electromagnetic coil disposed around the antenna adjacent to its substrate end; anda DC power supply connected to the electromagnetic coil.
