  • Patent number: 8901654
    Abstract: A material stack including a semiconductor channel portion, a gate dielectric, a gate electrode, and a gate cap dielectric portion is formed on an insulator layer. The material stack is laterally enclosed by a dielectric spacer including a dielectric material that is different from the dielectric material of the insulator layer. The material stack and the dielectric spacer are undercut by an isotropic etch that removes the material of the insulator layer selective to the material of the dielectric spacer. A selective epitaxy process is employed to deposit a doped semiconductor material, which forms a source region and a drain region that are epitaxially in contact with the semiconductor channel portion. Metal semiconductor alloy portions can be formed on the source region and the drain region.
