摘要:
With regard to a semiconductor apparatus thermally stable in a post process and suitable for fabricating a gate insulator having a laminated structure with various high permittivity oxides and a process of producing the same, in order to achieve high function formation of a gate insulator 8, a silicon nitride film specific inductive capacity of which is approximately twice as much as that of silicon oxide and which is thermally stable and is not provided with SinullH bond, is used as at least a portion of the gate insulator 8. Further, an effective thickness of a gate insulator forming a multilayered structure insulator laminated with a metal oxide having high dielectric constant, in conversion to silicon oxide, can be thinned to less than 3 nm while restraining leakage current.
