Abstract: In a semiconductor device including a carbon-containing electrode and a method for fabricating the same, an electrode has a high work function due to a carbon-containing TiN layer contained therein. It is possible to provide a dielectric layer having a high permittivity and thus to reduce the leakage current by forming an electrode having a high work function. Also, sufficient capacitance of a capacitor can be secured by employing an electrode having a high work function and a dielectric layer having a high permittivity.
