Abstract:
A FinFET device and fabrication method thereof is provided. The method includes: providing a semiconductor substrate and fins. Each fin includes a first sidewall region and a second sidewall region. An interlayer dielectric layer is formed on the semiconductor substrate and on the fins, with openings. Then a target work function layer is formed on sidewalls and on a bottom of each opening. The target work function layer includes a first target region covering the first sidewall region, a second target region covering the second sidewall region, and a third portion on the top surface of each fin. The second target region and the third portion of the target work function layer is doped with modification ions; and has a second effective work function value greater than a first effective work function value of the first target region of the target work function layer.

Claim (Index 16):
The FinFET according to  claim 15 , wherein:\n the target work function layer includes a first target region covering the first sidewall region, a second target region covering the second sidewall region, and a third portion on the top surface of each fin; the second target region and the third portion of the target work function layer on the top surface of each fin is doped with modification ions; and the first target region of the target work function layer has a first effective work function value, while the second target region and the third portion of the target work function has a second effective work function value greater than the first effective work function value.
