  • Patent number: 11640986
    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 interlayer dielectric thickness and to an enlargement of critical dimensions of a metal gate.
