Abstract:
A semiconductor device and a fabrication method are provided. The fabrication method includes providing a gate structure on a substrate and a first protective layers on the gate structure; forming an initial sidewall spacer on a sidewall of each of the gate structure and the first protective layer; forming a first sidewall spacer on a sidewall of the initial sidewall spacer, the first and initial sidewall spacers being made of different materials; forming a second sidewall spacer by removing a portion of the initial sidewall spacer, leaving a trench formed above the second sidewall spacer and between the first sidewall spacer and the first protective layer; and forming a second protective layer in the trench, the second protective layer and the first sidewall spacer being made of a same material. The second sidewall spacer has a top surface higher than or level with a top surface of the gate structure.

Claim (Index 15):
The semiconductor device according to  claim 14 , wherein:\n the semiconductor device further includes an interlayer dielectric layer covering the third sidewall spacer, the first sidewall spacer, the second protective layer, the first protective layer and the substrate; and a contact hole extends through the interlayer dielectric layer and is located between adjacent gate structures, the contact hole exposing top and sidewall surfaces of the third sidewall spacer, the top surface of the first sidewall spacer, a top surface of the second protective layer, and the substrate.
