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 11):
A method for fabricating a semiconductor structure, comprising:\n providing a base substrate having a first well region doped with a first type of doping ions and a second well region doped with a second type of doping ions adjacent to the first well region; forming a first insulation layer over the base substrate in the second well region, wherein the first insulation layer divides 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; forming a gate structure on the first well region and a first mask gate structure on the second well region, wherein the gate structure is also formed on the first region of the second well region and the first mask gate structure is formed on a portion of the second region adjacent to the first region; and forming 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 region at a side of the mask gate structure away from the isolation layer.
