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 19):
The method according to  claim 17 , wherein the gate structure is a dummy gate structure, and the method further comprises:\n forming a dielectric layer on the base substrate exposed by the gate structure after forming doped the source/drain regions; removing the gate structure to form a gate opening; and forming a metal gate structure in the gate opening.
