Abstract:
A semiconductor structure and a method for fabricating the semiconductor structure are provided. The method includes providing a base substrate, and forming an interlayer dielectric layer on the base substrate and having an opening exposing surface portions of the base substrate. The method also includes forming a stacked structure on a bottom and sidewall of the opening and on a top of the interlayer dielectric layer. In addition, the method includes removing at least a first portion of the stacked structure from the top of the interlayer dielectric layer. Further, the method includes performing an annealing treatment on the base substrate, and forming a gate structure by filling the opening with a metal layer.

Claim (Index 8):
The method according to  claim 3 , wherein removing the first portion of the stacked structure from the top of the interlayer dielectric layer and removing the second portion of the stacked structure from the sidewall of the opening include:\n forming a filling layer in the opening, and on the stacked structure; performing a first removal process to remove the filling layer over the top of the interlayer dielectric layer until a top surface of the stacked structure is exposed; performing a second removal process to remove portions of a thickness of the filling layer in the opening; removing the first and second portions of the stacked structure above a top surface of the remaining filling layer; and removing the remaining filling layer.
