Abstract:
Semiconductor structures and fabrication methods thereof are provided. An exemplary semiconductor structure includes a base substrate having a first well and a second well region; a first insulation layer over the base substrate and dividing the second well region into a first region adjacent to the first well region, a second region away from the first well region and a third region under the first insulation layer; a gate structure over the base substrate in the first well region and the first region of the second well region; a first mask gate structure on a portion of the second region adjacent to the first region; a first stress layer on the first well region at a side of gate structure away from the first insulation layer; and a second stress layer on the second well regions at a side of the mask gate structure away from the isolation layer.

Claim (Index 13):
The method according to  claim 11 , wherein the semiconductor structure is a fin field-effect transistor, the base substrate includes a semiconductor substrate, a plurality of first fins and a plurality of second fins on the semiconductor substrate and distributed along a length direction of the first fins and the second fins, the first well region and the second well region are in the first fins and distributed along a direction toward the second fins, and the second well region extends into the second fins, wherein:\n forming the first insulation layer in the second well region includes forming the first insulation layer between the first fins and the second fins, wherein the first insulation layer covers portions of side surfaces of the first fins adjacent to the second fins; and forming the gate structure and the first mask gate structure includes forming the first gate structure on the first fins and the first mask gate structure on the second fins, wherein the first gate structure is across the first fins and on portions of top surfaces and side surfaces of the first fins and the first mask gate structure is on the second fins.
