When a fin is formed, a dummy gate across the fin is formed on the fin, a spacer is formed on sidewalls of the dummy gate, and a cover layer is formed on the first dielectric layer and on the fin outside the dummy gate and the spacer; then, an self-aligned and elevated source/drain region is formed at both sides of the dummy gate by the spacer, wherein the upper surfaces of the gate and the source/drain region are in the same plane. The upper surfaces of the gate and the source/drain region are in the same plane, making alignment of the contact plug easier; and the gate and the source/drain region are separated by the spacer, thereby improving alignment accuracy, solving inaccurate alignment of the contact plug, and improving device AC performance.
