A semiconductor device exhibits a stable driving force and high performance reliability. The semiconductor device has at least one transistor having a gate insulating film formed on a element region in a semiconductor substrate, a gate electrode formed on the gate insulating film, and a diffused layer in element regions on both sides of the gate electrode. The device also has a barrier insulating film formed so as to cover the transistor and the diffused layer. The height from a surface of the semiconductor substrate to the barrier insulating film is greater than the height from the surface, of the interface between the gate insulating film and the gate electrode.
