Abstract
A system for performing sputter disposition on a substrate. A divergent ion current source generates a divergent ion beam. The ion current source has a central axis about which ions are directed toward a surface of a negatively biased target. A rotating substrate is positioned proximate to the target. The central axis of the ion current source is normal to the surface of the target and parallel to a deposition surface of the rotating substrate.
