Abstract:
1. A semiconductor apparatus comprising: a substrate; an insulating film formed on the substrate; a first gate electrode made of a first monocrystal semiconductor material formed on the insulating film; a first gate insulating film made of a first monocrystal rare earth oxide and formed on the first gate electrode; a monocrystal strained Si layer formed on the first gate insulating film to be in contact with the first gate insulating film; a second gate insulating film made of a second monocrystal rare earth oxide and formed at a position opposed to the first gate insulating film on the monocrystal strained Si layer to be in contact with the monocrystal strained Si layer; and a second gate electrode made of a second monocrystal semiconductor material and formed on the second gate insulating film.
