| 简介 |
Embodiments include multi-fin finFET structures with epitaxially-grown merged source/drains and methods of forming the same. Embodiments may include an epitaxial insulator layer above a base substrate, a gate structure above the epitaxial insulator layer, a semiconductor fin below the gate structure, and an epitaxial source/drain region grown on the epitaxial insulator layer adjacent to an end of the semiconductor fin. The epitaxial insulator layer may be made of an epitaxial rare earth oxide material grown on a base semiconductor substrate. Embodiments may further include fin extension regions on the end of the semiconductor fin between the end of the end of the semiconductor fin and the epitaxial source/drain region. In some embodiments, the end of the semiconductor fin may be recessed below the gate structure. |
