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 1):
A semiconductor structure, comprising:\n a fin structure having a first fin and a second fin formed on a semiconductor substrate; inner fin spacers formed along inner sidewalls of the first and the second fins, wherein the inner fin spacers have a height H i ; outer fin spacers formed along outer sidewalls of the first and the second fins, wherein the outer fin spacers have a height H o , H o  being substantially less than H i ; and an epitaxial structure formed over both the first and the second fins, wherein the epitaxial structure encloses an air gap formed by the inner fin spacers, the air gap having at least a width P, wherein P is a separation distance between opposing sidewalls of the inner fin spacers.
