Abstract:
Semiconductor structure and fabrication method are provided. The method includes: providing a base substrate including a first region, a second region and a third region between the first and the second region; forming a dummy gate structure extending from the first region to the second region and through the third region; forming first doped source/drain regions in the base substrate on both sides of the dummy gate structure in the first region; forming second doped source/drain regions in the base substrate on both sides of the dummy gate structure in the second region; forming an opening in the dummy gate structure in the third region and exposing the base substrate in the third region; and forming an interlayer dielectric layer within the opening to have a top surface coplanar with the dummy gate structure.

Claim (Index 4):
The fabrication method according to  claim 1 , wherein forming the first doped source/drain regions include:\n forming first openings in the base substrate on both sides of the dummy gate structure in the first region using an etching process; forming epitaxial layers in the first openings by a selective epitaxial deposition method; and\n doping the epitaxial layers to form the first doped source/drain regions.
