Abstract:
Semiconductor structures and fabrication methods thereof are provided. An exemplary fabrication process includes providing a base substrate; forming a carbon-containing dielectric layer over the base substrate; and performing a chemical mechanical polishing (CMP) process on the carbon-containing dielectric layer. The chemical mechanical polishing process includes performing a plurality of polishing processes on the carbon-containing dielectric layer and a weak acid solution is used to clean a polishing pad before and after each of the polishing processes.

Claim (Index 9):
The method according to  claim 8 , wherein:\n a down force of the third polishing process is in a range of approximately 1 psi-3 psi; a platen speed of the third polishing process is in range of approximately 30 rpm-90 rpm; a flow rate of the polishing slurry of the third polishing process is in a range of approximately 200 ml/min-400 ml/min; and a polishing time of the third polishing process is in a range of approximately 20 s-60 s.
