Abstract: A FinFET is provided including a channel region containing a constituent element and excess atoms, the constituent element belonging to a group of the periodic table of elements, wherein said excess atoms are nitrogen, or belong to said group of the periodic table of elements, and a concentration of said excess atoms in the channel region is in the range between about 1019 cm?3 and about 1020 cm?3.

Abstract: A finFET device and methods of forming a finFET device are provided. The method includes depositing a dummy gate over and along sidewalls of a fin extending upwards from a semiconductor substrate, forming a first gate spacer along a sidewall of the dummy gate, and plasma-doping the first gate spacer with carbon to form a carbon-doped gate spacer. The method further includes forming a source/drain region adjacent a channel region of the fin and diffusing carbon from the carbon-doped gate spacer into a first region of the fin to provide a first carbon-doped region. The first carbon-doped region is disposed between at least a portion of the source/drain region and the channel region of the fin.

Abstract: A semiconductor device, and a method of manufacturing, is provided. A dummy gate is formed on a semiconductor substrate. An interlayer dielectric (ILD) is formed over the semiconductor fin. A dopant is implanted into the ILD. The dummy gate is removed and an anneal is performed on the ILD. The implantation and the anneal lead to an enhancement of channel resistance by a reduction in gate dielectric thickness and to an enlargement of critical dimensions of a metal gate.
