摘要:
A semiconductor device includes a Si substrate, a gate insulating film formed on the Si substrate, the gate insulating film being formed of an oxide film containing at least one selected from the group of Zr, Hf, Ti and a lanthanoid series metal, and having a single local minimal value on a high binding energy side of an inflection point in first differentiation of an O1s photoelectron spectrum, and a gate electrode formed on the gate insulating film.
