20150214366 | EMBEDDED SOURCE OR DRAIN REGION OF TRANSISTOR WITH DOWNWARD TAPERED REGION UNDER FACET REGION - In some embodiments, a field effect transistor (FET) structure comprises a body structure, dielectric structures, a gate structure and a source or drain region. The gate structure is formed over the body structure. The source or drain region is embedded in the body structure beside the gate structure, and abuts and is extended beyond the dielectric structure. The source or drain region contains stressor material with a lattice constant different from that of the body structure. The source or drain region comprises a first region formed above a first level at a top of the dielectric structures and a second region that comprises downward tapered side walls formed under the first level and abutting the corresponding dielectric structures. | 07-30-2015 |
