Zusammenfassung:The semiconductor device includes a semiconductor fin, and a gate stack over the semiconductor fin. The gate stack includes a gate dielectric layer over a channel region of the semiconductor fin, a work function material layer over the gate dielectric layer, wherein the work function material layer includes dopants, and a gate electrode layer over the work function material layer. The gate dielectric layer is free of the dopants.
