Abstract:
Epitaxial structures of a fin-like field effect transistor (FinFET) device includes a substrate, a fin structure including two fins, inner and outer fin spacers formed along both sidewalls of the fins, and isolation regions formed around the fins. The FinFET device further includes a gate structure formed over the fin structure and an epitaxial structure formed over the fin structure in a source/drain region. The epitaxial structure is formed by merging the fins with at least one epitaxial semiconductor layer and includes an air gap having a volume determined by the height and separation distance of the inner fin spacers.

Claim (Index 21):
A device comprising:\n a first fin structure and a second fin structure disposed over a substrate, the first fin structure having a first sidewall surface, a second sidewall surface opposing the first sidewall surface and a top surface extending from the first sidewall surface to the second sidewall surface; a first dielectric spacer disposed along the first sidewall surface of the first fin structure, the first dielectric spacer extending to a first height above the substrate; a second dielectric spacer disposed along the second sidewall surface of the first fin structure, the second dielectric spacer extending to a second height above the substrate, the second height being different than the first height; and an epitaxial semiconductor structure disposed over the first fin structure and the second fin structure, wherein the epitaxial semiconductor structure encloses an air gap disposed between the first fin structure and the second fin structure.
