Abstract:
A semiconductor structure and a method for fabricating the semiconductor structure are provided. The method includes forming a gate structure and a dielectric layer on a substrate; and forming a sidewall spacer on a sidewall surface of the gate structure. The method also includes forming a source and drain doped region in the substrate on both sides of the gate structure. The dielectric layer covers a surface of the sidewall spacer. In addition, the method includes forming a source-drain plug in the dielectric layer. The source-drain plug is connected to the source and drain doped region. Moreover, the method includes forming an isolation opening in the dielectric layer by at least partially removing the sidewall spacer. Further, the method includes forming an isolation structure in the isolation opening, wherein the isolation structure has a dielectric constant less than the sidewall spacer.

Claim (Index 3):
The method according to  claim 1 , wherein forming the isolation structure in the isolation opening includes:\n forming a conformal layer on a bottom and a sidewall surface of the isolation opening, and forming an isolation material layer in the isolation opening after forming the conformal layer.
