    摘要: In a MIS transistor of which gate length is 10 nm or less, a gate insulator comprising a silicon oxide film formed on a silicon substrate and a high-k film formed on the silicon oxide film has a nitrided region including more nitrogen at the lateral side than at the central side in the gate-length direction, and including more nitrogen at the upper side than at the lower side in the film thickness direction. The reliability and characteristics of a MIS transistor using a gate insulator including a high-k (high dielectric constant) film is enhanced.

    摘要: A base insulating film containing hafnium and oxygen is formed on a silicon oxide (SiO2) film formed on a main surface of a substrate. Subsequently, a metal thin film thinner than the base insulating film and made of only a metal element is formed on the base insulating film, and a protective film having humidity resistance and oxidation resistance is formed on the metal thin film. Then, by diffusing the entire metal element of the metal thin film into the base insulating film in a state of having the protective film, a mixed film (high dielectric constant film) thicker than the silicon oxide film and having a higher dielectric constant than silicon oxide and containing hafnium and oxygen of the base insulating film and the metal element of the metal thin film is formed on the silicon oxide film.
