Abstract:
A semiconductor structure including a multi-faceted epitaxial semiconductor structure within both a source region and a drain region and on exposed surfaces of a semiconductor fin is provided. The multi-faceted epitaxial semiconductor structure includes faceted epitaxial semiconductor material portions located on different portions of each vertical sidewall of the semiconductor fin and a topmost faceted epitaxial semiconductor material portion that is located on an exposed topmost horizontal surface of the semiconductor fin. The multi-faceted epitaxial semiconductor structure has increased surface area and thus an improvement in contact resistance can be obtained utilizing the same.

Claim (Index 9):
The method of  claim 1 , wherein said forming said multi-faceted epitaxial semiconductor structure comprises:\n forming a multilayered liner structure straddling over other portions of said at least one semiconductor fin; selectively etching said multilayered liner structure to expose a topmost surface of said at least one semiconductor fin and an upper portion of each of said vertical sidewalls of said at least one semiconductor fin; epitaxially growing an upper faceted epitaxial semiconductor material portion at said upper portion of each of said vertical sidewalls of said at least one semiconductor fin, and said topmost faceted epitaxial semiconductor material portion on said exposed topmost horizontal surface of said at least one semiconductor fin; and performing, any number of, sequential steps of: selectively etching a remaining portion of said multilayer liner structure to expose another portion of each of said vertical sidewalls of said at least one semiconductor fin, and epitaxially growing a faceted epitaxial semiconductor material portion at said another portion of each of said vertical sidewalls of said at least one semiconductor fin in a top-down fashion to provide remaining faceted epitaxial semiconductor material portions along each of said vertical sidewalls of said at least one semiconductor fin.
