Abstract: A method (100) of forming a transistor includes forming a gate structure (106, 108) over a semiconductor body and forming recesses (112) substantially aligned to the gate structure in the semiconductor body. Carbon-doped silicon is then epitaxially grown (114) in the recesses, followed by forming sidewall spacers (118) over lateral edges of the gate structure. The method continues by implanting source and drain regions in the semiconductor body (120) after forming the sidewall spacers. The carbon-doped silicon formed in the recesses resides close to the transistor channel and serves to provide a tensile stress to the channel, thereby facilitating improved carrier mobility in NMOS type transistor devices.
