Abstract:
A method of manufacturing a semiconductor device includes providing a semiconductor structure including a substrate, a semiconductor fin on the substrate, and a dummy gate structure on the semiconductor fin. The dummy gate structure includes a dummy gate dielectric layer on the semiconductor fin and a dummy gate on the dummy gate dielectric layer. The method also includes forming an interlayer dielectric layer on the semiconductor substrate, planarizing the interlayer dielectric layer to expose an upper surface of the dummy gate, and performing a first doping implant into the semiconductor fin through the dummy gate to form an anti-puncture region in the semiconductor fin. The anti-puncture region has an upper surface lower than an upper surface of a trench isolation portion surrounding the semiconductor fin to prevent a punch through of a source and drain, reducing a current leakage and parasitic capacitance of the semiconductor device.

Claim (Index 18):
The semiconductor device of  claim 17 , further comprising:\n a trench isolation portion on the substrate and surrounding the semiconductor fin; wherein the anti-puncture region has an upper surface lower than an upper surface of the trench isolation portion.
