Abstract:
A semiconductor device includes a gate stack formed on an active region in a p-type field effect transistor (pFET) portion of a silicon-on-insulator (SOI) substrate. The SOI substrate includes a n-type field effect transistor (nFET) portion. A gate spacer is formed over the gate stack. A source region and a drain region are formed within a first region and a second region, respectively, of the pFET portion of the semiconductor layer including embedded silicon germanium (eSiGe). A source region and a drain region are formed within a first region and a second region, respectively, of the nFET portion of the semiconductor layer including eSiGe. The source and drain regions within the pFET portion includes at least one dimension that is different from at least one dimension of the source and drain regions within the nFET portion.
