Patent ID: 8916932

Claim:
A semiconductor device comprising: a substrate; and a fin-shaped field effect transistor (FINFET) disposed on the substrate, the FINFET including: a set of fins disposed proximate a gate; and a set of epitaxial regions disposed in a source/drain region on the set of fins, the set of epitaxial regions including: a first epitaxial region on a first inner surface of a first outer fin, the first epitaxial region having a first thickness defined as one of: a) a distance from the first inner surface to an edge of the epitaxial region in the case of a non-merged state of adjacent inner epitaxial regions of adjacent fins, and b) half of a distance from the first inner surface to an opposing inner surface of an adjacent fin in a merged state of adjacent inner epitaxial regions of adjacent fins, and a second epitaxial region with a second thickness disposed on a first outer surface of the first outer fin, wherein the second thickness is thinner than the first thickness.
