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 8):
A semiconductor structure, comprising:\n a semiconductor substrate; a fin structure comprising a first fin and a second fin formed on the semiconductor substrate, wherein an inner fin spacer and an outer fin spacer are formed vertically along two opposing sidewalls of each of the first and the second fins, and wherein the inner fin spacer of the first fin is disposed adjacent to the inner fin spacer of the second fin, the inner fin spacers of the first and the second fins having a height H i  and separated by a distance P, both of the outer fin spacers having a height H o , wherein H i  is substantially greater than H o ; a gate structure formed over the fin structure; an epitaxial structure formed in a source region and a drain region of the fin structure, wherein the epitaxial structure merges the first and the second fins with at least one epitaxial semiconductor layer, and wherein the at least one epitaxial semiconductor layer and the inner fin spacers form an air gap; and isolation regions formed on the semiconductor substrate to isolate the first and the second fins.
