Abstrakt: A study is made of the impact of embedded epitaxial Si:C source/drain regions on the DC and low-frequency (LF) noise characteristics of nMOSFETs with 1.4 nitrided oxide gate dielectric. It is shown that a ~10% improvement in ION is achieved for a C concentration of 1%, with not much further improvement going to 1.5%. At the same time, no change of the 1/f noise is observed, indicating that the gate stack integrity is preserved throughout the Selective Epitaxial Growth process.
