Claim 25:
26. The semiconductor device of claim 1, further comprising one or more NMOS transistors,
wherein the one or more NMOS transistors include:
a metal gate electrode component of the one or more NMOS transistors that forms at least a portion of a gate electrode of the one or more NMOS transistors and is located above the substrate;
a gate insulating film of the one or more NMOS transistors located between the metal gate electrode component of the one or more NMOS transistors and the substrate, the gate insulating film of the one or more NMOS transistors formed of a material of the one or more NMOS transistors comprising a metal oxide, a metal silicate, a metal oxynitride, or a nitrided metal silicate, wherein the material of the one or more NMOS transistors consists of or includes hafnium, lanthanum, aluminum, zirconium, or tantalum;
a first insulating film of the one or more NMOS transistors located on opposite sides of the metal gate electrode component of the one or more NMOS transistors;
a second insulating film of the one or more NMOS transistors located between the first insulating film of the one or more NMOS transistors and the metal gate electrode component of the one or more NMOS transistors;
a source/drain material of the one or more NMOS transistors;
a third insulating film of the one or more NMOS transistors, located on opposite sides of the metal gate electrode component of the one or more NMOS transistors and of the first insulating film of the one or more NMOS transistors; and
a first Ti—N film of the one or more NMOS transistors, the first Ti—N film of the one or more NMOS transistors being located between the metal gate electrode component of the one or more NMOS transistors and the gate insulating film of the one or more NMOS transistors, and the first Ti—N film including at least the Ti and the N.
