    摘要: In a semiconductor device formed on a silicon surface which has a substantial (110) crystal plane orientation, the silicon surface is flattened so that an arithmetical mean deviation of surface Ra is not greater than 0.15nm, preferably, 0.09nm, which enables to manufacture an n-MOS transistor of a high mobility. Such a flattened silicon surface is obtained by repeating a deposition process of a self-sacrifice oxide film in an oxygen radical atmosphere and a removing process of the self-sacrifice oxide film, by cleaning the silicon surface in deaerated H 2 O or a low OH density atmosphere, or by strongly terminating the silicon surface by hydrogen or heavy hydrogen. The deposition process of the self-sacrifice oxide film may be carried out by isotropic oxidation.

    摘要: In order to provide a semiconductor device having good quality by keeping the relative permittivity of a High-K insulation film in a high state, or to provide a method for manufacturing a semiconductor device in which the relative permittivity of the High-K insulation film can be kept in a high state, a semiconductor device is disclosed that includes a silicon substrate, a gate electrode layer, and a gate insulation film between the silicon substrate and the gate electrode layer. The gate insulation film is a high relative permittivity (high-k) film being formed by performing a nitriding treatment on a mixture of a metal and silicon. The High-K film itself becomes a nitride so as to prevent SiO 2 from being formed.
