Abstract:
A method for fabricating a semiconductor device includes forming a fin extending along a first direction on a semiconductor substrate and forming a sacrificial gate electrode structure extending along a second direction substantially perpendicular to the first direction over the fin. The sacrificial gate electrode structure comprises a sacrificial gate dielectric layer and a sacrificial gate electrode layer disposed over the sacrificial gate dielectric layer. Opposing gate sidewall spacers are formed extending along the second direction, on opposing sides of the sacrificial gate electrode layer. The sacrificial gate electrode layer is removed to form a gate space. Fluorine is implanted into the gate sidewall spacers after removing the gate electrode layer by performing a first fluorine implantation. The sacrificial gate dielectric layer is removed and a high-k gate dielectric layer is formed in the gate space. Fluorine is implanted into the gate sidewall spacers and the fin after forming the high-k gate dielectric layer by performing a second fluorine implantation.

Claim (Index 19):
The method according to  claim 17 , wherein the second fluorine implantation is performed at an energy ranging from 50 eV to 500 eV, and a dose ranging from 1\u00d710 13  atoms/cm 2  to 1\u00d710 16  atoms/cm 2 .
