Abstract:
Semiconductor structures and fabrication methods thereof are provided. An exemplary fabrication method includes providing a base substrate; forming a gate structure over the base substrate; forming a mask layer on a top surface of the gate structure; forming pocket regions in the base substrate at both sides of the gate structure; after forming the pocket regions, forming a first protective portion covering a top surface of the mask layer and protruding from sidewall surfaces of the gate structure; and after forming the first protective portion, forming doped source/drain regions in the base substrate and portions of the pocket regions at both sides of the gate structure.

Claim (Index 11):
The method according to  claim 10 , wherein:\n a wet etching process is used to remove the portions of the first capping film on the base substrate in the first region and on the top and sidewall surfaces of the gate structure in the first region to form the first capping layer, wherein:\n an etching solution of the wet etching process includes a phosphorus solution; and \n a temperature of the wet etching process is in a range of approximately 30\u00b0 C.-100\u00b0 C.
