Abstract:
1. An ion source for ion beam deposition comprising: a first cylindrical anode; a second cylindrical anode, the first cylindrical anode being concentric with the second cylindrical anode; an electron source positioned within at least one of the first cylindrical anode and the second cylindrical anode; a first voltage source input configured to apply a first voltage from a first voltage source to the first cylindrical anode to deposit a first thickness of a source material in a first zone on a substrate; and a second voltage source input configured to apply a second voltage from a second voltage source that is separate from the first voltage source to the second cylindrical anode to deposit a second thickness of the source material in a second zone on the substrate, wherein the first voltage is different than the second voltage and the first thickness is different than the second thickness.
