Abstract:
The capacitance between gate structures and source/drain contacts of FinFET devices is reduced by the incorporation of inner spacers in the top portions of the gate structures. A replacement metal gate process used in the fabrication of such devices includes formation of the inner spacers following partial removal of dummy gate material. The remaining dummy gate material is then removed and replaced with gate dielectric and metal gate material.
