Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate including silicon; and
one or more PMOS transistors that include:
a metal gate electrode component that forms at least a portion of a gate electrode and is located above the substrate;
a first insulating film located on opposite sides of the metal gate electrode component;
a gate insulating film located between the metal gate electrode component and the substrate, the gate insulating film formed of a material comprising a metal oxide, a metal silicate, a metal oxynitride, or a nitrided metal silicate, wherein the material includes at least one of hafnium (Hf), lanthanum (La), aluminum (Al), zirconium (Zr), or tantalum (Ta);
a second insulating film located between the first insulating film and the metal gate electrode component;
a source/drain located at the same vertical height as at least a portion of a silicon-based material and including a source/drain material, the source/drain material having a lattice constant different from a lattice constant of the silicon-based material, wherein the substrate comprises at least the portion of the silicon-based material;
a portion of the source/drain is located at the same vertical height as or above a portion of the metal gate electrode component;
a third insulating film located on opposite sides of the metal gate electrode component and of the first insulating film; and

a first Ti—N film located between the metal gate electrode component and the gate insulating film, the first Ti—N film at least including titanium (Ti) and nitrogen (N).
