This document discusses the Perkin Elmer PE 4410 sputtering deposition system. It notes that the PE 4410 uses a delta-shaped cathode that eliminates the need for a large uniformity aperture, dramatically increasing throughput while maintaining uniformity. The delta cathode also allows for higher target utilization of up to 35% before needing to change targets compared to circular cathodes. This results in lower cost per wafer and less frequent target changes for the PE 4410 sputtering system.
