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 1):
A fabrication method of a semiconductor structure, comprising:\n providing a base substrate including a first region, a second region, and a third region between the first region 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; after forming the first doped source/drain regions and the second doped source/drain regions, forming an opening in the dummy gate structure in the third region, exposing the base substrate in the third region; and forming an interlayer dielectric layer inside the opening, wherein the interlayer dielectric layer has a top surface coplanar with the dummy gate structure.
