Abstract
A semiconductor device includes a substrate including a first semiconductor material, a gate structure formed on the substrate, and a source stressor and a drain stressor formed in the substrate respectively in a recess at two sides of the gate structure. The source stressor and the drain stressor respectively include at least a first quantum wire and at least a second quantum wire formed on the first quantum wire. The first quantum wire includes the first semiconductor material and a second semiconductor material, and a lattice constant of the second semiconductor material is larger than a lattice constant of the first semiconductor material. And the second quantum wire includes the second semiconductor material.
