Claim:
1. A FinFET device, comprising: a substrate; a fin disposed on the substrate; a gate structure disposed on a portion of the fin; a first protection layer and a second protection layer disposed adjacent the fin, wherein each of the first protection layer and the second protection layer is disposed adjacent to portions of the fin that are not covered by the gate structure, wherein the first protection layer directly physically contacts a first side of the fin and a the second protection layer directly physically contacts an opposite second side of the fin, and wherein the fin has a dopant concentration that increases from a plane oriented parallel to a current flow that vertically bisects the fin towards an interface between the first protection layer and the first side and that increases from the plane towards an interface between the second protection layer and the second side; and source and drain regions disposed at either end of the fin.
