     MFC gas control system;
     Advanced RF automatically matching network;
     DC and RF power are mounted in the main frame;
     Fast Cycle Load Lock Operation ;
     High rate DeltaTM DC magnetron sputtering;
     High throughput operation: Automated load lock and controller sequences provide for
       efficient pump down and pallet transfer to process chamber
     High uniformity: 7% deposition uniformity guaranteed with water-cooled rotating annular
       substrate table; 5% achievable.
     Ultra-clean vacuum: Cryopump and Meissner-trapped process chamber ensures
       contamination-free conditions especially important for critical processes such as the
       deposition of aluminum and platinum;
     Easy maintenance: Removable deposition shields permit easy system cleaning. Automatic
       cryopump regeneration minimizes downtime and inconvenience;
     Specialized pallets for ease of substrate leading/unloading;
     "Drop in" target for quick target changes, no screw to both with;
     "Snap-out" deposition shields for quick, easy maintenance;
     Fail-safe system protection: Water flow switches on cathodes, chamber and vacuum
       system automatically shut the system down in case of cooling system failure
