Abstract:
1. A semiconductor device comprising: a semiconductor body comprising a first semiconductor material; a first gate electrode adjacent a second gate electrode, the first gate electrode and the second gate electrode disposed over an upper surface of the semiconductor body; a first sidewall spacer disposed along a first sidewall of the first gate electrode; a second sidewall spacer disposed along a second sidewall of the second gate electrode, the first sidewall spacer and the second sidewall spacer facing each other; a shared source/drain region between the first sidewall spacer and the second sidewall spacer, wherein the shared source/drain region comprises the first semiconductor material on the upper surface of the semiconductor body; a first region within the shared source/drain region adjacent the first gate electrode comprising a second semiconductor material embedded therein; a second region within the shared source/drain region adjacent the second gate electrode comprising the second semiconductor material embedded therein; and a third region between the first and second regions, the third region separating the first region from the second region and comprising the first semiconductor material, wherein the first semiconductor material is different than the second semiconductor material.
