Abstract
A system and method for performing sputter deposition on a substrate. First, second, and third divergent ion current sources generate first, second and third divergent ion beams, respectively. The substrate faces the first ion current source. The first target faces the second ion current source, and the second target faces the third ion current source. The central axis of each ion current source is orthogonal to the central axes of the other two ion current sources.
