Abstract: In plasma doping a non-planar semiconductor device, a substrate having a non-planar semiconductor body formed thereon is obtained. The substrate having the non-planar semiconductor body may be placed into a chamber. A plasma may be formed in the chamber and the plasma may contain dopant ions. A first bias voltage may be generated to implant dopant ions into a region of the non-planar semiconductor body. A second bias voltage may be generated to implant dopant ions into the same region. In one example, the first bias voltage and the second bias voltage may be different.
