Abstract: A method for fabricating semiconductor device includes the steps of first forming a metal gate on a substrate and a spacer around the metal gate, in which the metal gate comprises a high-k dielectric layer, a work function metal layer, and a low-resistance metal layer. Next, part of the high-k dielectric layer is removed to form an air gap between the work function metal layer and the spacer.
