Abstract
A device includes a semiconductor substrate, a fin structure on the semiconductor substrate, a gate structure on the fin structure, and a pair of source/drain features on both sides of the gate structure. The gate structure includes an interfacial layer on the fin structure, a gate dielectric layer on the interfacial layer, and a gate electrode layer of a conductive material on and directly contacting the gate dielectric layer. The gate dielectric layer includes nitrogen element.
