Abstract:
1. A method for forming a non-planar semiconductor device, comprising: forming a fin, a first current electrode, and a second current electrode of the non-planar semiconductor device, wherein the fin, the first current electrode, and the second current electrode each comprises silicon; providing a source of germanium to the fin, to the first current electrode, and to the second current electrode, wherein providing the source of germanium to the fin comprises implanting the fin with germanium; oxidizing to distribute the germanium throughout the fin, to form an inner region and an outer region of the first current electrode, and to form an inner region and an outer region of the second current electrode, wherein the outer region of the first electrode comprises germanium but the inner region of the first electrode does not comprise germanium, and wherein the outer region of the second current electrode comprises germanium but the inner region of the second electrode does not comprise germanium; and completing formation of the non-planar semiconductor device.
