Abstract:
A semiconductor device comprising:a first MOSFET including: a first gate electrode formed on a first semiconductor layer in a first region of a semiconductor substrate; a first channel region formed immediately below said first gate electrode in the first semiconductor layer; a first diffusion layer constituting source/drain regions formed at both the sides of said first channel region in the first semiconductor layer; a first epitaxial layer formed on said first diffusion layer; and a first silicide layer formed on said first epitaxial layer; and a second MOSFET including: a second gate electrode formed on a second semiconductor layer in a second region of the semiconductor substrate; a second channel region formed immediately below said second gate electrode in the second semiconductor layer; a second diffusion layer constituting source/drain regions formed at both the sides of said second channel region in the second semiconductor layer; and a second silicide layer formed on said second diffusion layer, wherein the second semiconductor layer contains silicon, and said second diffusion layer of said second MOSFET contains carbon.
