Abstract:
A method of forming source/drain features in a FinFET device includes providing a fin formed over a substrate and a gate structure formed over a fin, forming a recess in the fin adjacent to the gate structure, forming a first epitaxial layer in the recess, forming a second epitaxial layer over the first epitaxial layer, and forming a third epitaxial layer over the second epitaxial layer. The second epitaxial layer may be doped with a first element, while one or both of the first and the third epitaxial layer includes a second element different from the first element. One or both of the first and the third epitaxial layer may be formed by a plasma deposition process.

Claim (Index 25):
The method of  claim 22 , wherein forming the material layer includes implementing an atomic-layer deposition process, and wherein forming the first or the second epitaxial semiconductor layers includes implementing a selective epitaxial growth process.
