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 15):
The method according to  claim 14 , wherein forming the first insulation layer comprises:\n forming an insulation material layer on the base substrate exposed by the first fins and the second fins to cover top surfaces of the first fins and the second fins; and forming the first insulation layer by performing an etch-back process on the insulation material layer, wherein the etch-back process includes:\n performing a first etch-back process on the insulation material layer to reduce a thickness of the insulation material layer on the second fins; \n forming an insulation mask layer on the etched insulation material layer and on portions of the second fins adjacent to the first fins; and \n performing a second etch-back process on remaining insulation material layer using the insulation mask layer as the etching mask to form the first insulation layer and the second insulation layer under the insulation mask layer.
