Abstract
Methods and apparatus provide for: a first source of plasma (first plasma), which includes a first species of ions, directing the first plasma out along a first axis; a second source of plasma (second plasma), which includes a second, differing, species of ions, directing the second plasma out along a second axis; and an accelerator system in communication with the first and second sources of plasma, and operating to: (i) accelerate the first species of ions at a first magnitude therethrough, and toward a semiconductor wafer, and (ii) simultaneously accelerate the second species of ions at a second magnitude, different from the first magnitude, therethrough, and toward the semiconductor wafer.
