A semiconductor device includes a first MIS transistor of a non-salicide structure and a second MIS transistor of a salicide structure which are both formed on a substrate of silicon. The first MIS transistor includes a first gate electrode of silicon, first sidewalls, a first source and drain, and plasma reaction films grown in a plasma atmosphere to cover the top surfaces of the first gate electrode and first source and drain, wherein the plasma reaction film prevents silicide formation on the first MIS transistor.
