Abstract:
A semiconductor device, an integrated circuit, and method for fabricating the same are disclosed. The semiconductor device includes a gate stack formed on an active region of a silicon-on-insulator substrate. A gate spacer is formed over the gate stack. A source region that includes embedded silicon germanium is formed within the semiconductor layer. A drain region that includes embedded silicon germanium is formed within the semiconductor layer. The source region includes an angled implantation region that extends into the embedded silicon germanium of the source region, and is asymmetric relative to the drain region.
