Abstract:
A method for fabricating a semiconductor device is disclosed. A dummy gate is formed on a semiconductor substrate. The dummy gate has a first sidewall and a second sidewall opposite to the first sidewall. A low-k dielectric layer is formed on the first sidewall of the dummy gate and the semiconductor substrate. A spacer material layer is deposited on the low-k dielectric layer, the second sidewall of the dummy gate, and the semiconductor substrate. The spacer material layer and the low-k dielectric layer are etched to form a first spacer structure on the first sidewall and a second spacer structure on the second sidewall. A drain doping region is formed in the semiconductor substrate adjacent to the first spacer structure. A source doping region is formed in the semiconductor substrate adjacent to the second spacer structure.

Claim (Index 6):
The method for fabricating a semiconductor device according to  claim 1 , wherein after forming the drain doping region in the semiconductor substrate adjacent to the first spacer structure and the source doping region in the semiconductor substrate adjacent to the second spacer structure, the method further comprises:\n forming a contact etch stop layer to cover the drain doping region, the source doping region, the first spacer material layer, and the second spacer material layer; depositing an inter-layer dielectric (ILD) layer on the contact etch stop layer; polishing the ILD layer, the contact etch stop layer, the first spacer structure, and second spacer structure, thereby exposing the dummy gate; and replacing the dummy gate with a metal gate.
