    Abstract: A finFET is formed having a fin with a source region, a drain region, and a channel region between the source and drain regions. The fin is etched on a semiconductor wafer. A gate stack is formed having an insulating layer in direct contact with the channel region and a conductive gate material in direct contact with the insulating layer. The source and drain regions are etched leaving the channel region of the fin. Epitaxial semiconductor is grown on the sides of the channel region that were adjacent the source and drain regions to form a source epitaxy region and a drain epitaxy region. The source and drain epitaxy regions are doped in-situ while growing the epitaxial semiconductor.

    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.
