Abstract:
A first and a second instance of a common structured stack are formed, respectively, on a first fin and a second fin. The common structured stack includes a work-function metal layer, and a barrier layer. The barrier layer of the first instance of the common structured stack is etched through, and the work-function metal layer of the first instance of the common structure is partially etched. The partial etch forms a thinner work-function metal layer, having an oxide of the work-function metal as a new barrier layer. A gate element is formed on the new barrier layer.

Claim (Index 13):
The method of  claim 7 , wherein the plurality of fins further includes a third Si fin, and wherein the method further comprises\n forming a third PMOS FinFET wherein forming the first PMOS FinFET comprises forming a third gate stack on a gate area of the third Si fin, wherein the third gate stack has a third work-function metal layer, wherein the third work-function metal layer has a thickness approximately mutually identical with the thickness of the first work-function metal layer and the second work-function metal layer, and wherein the third work-function metal layer comprises a work-function metal that is mutually identical with the work-function metal of the thickness of the first work-function metal layer and the second work-function metal layer, and wherein the third Si fin has a third concentration of Ge that is higher than the second concentration of Ge, wherein the third concentration of Ge, establishes, at least in part, a threshold voltage of the third PMOS FinFET that is lower than a threshold voltage of the second PMOS FinFET.
