摘要： The band tail state and defects in the band gap are reduced as much as possible, whereby optical absorption of energy which is in the vicinity of the band gap or less than or equal to the band gap is reduced. In that case, not by merely optimizing conditions of manufacturing an oxide semiconductor film, but by making an oxide semiconductor to be a substantially intrinsic semiconductor or extremely close to an intrinsic semiconductor, defects on which irradiation light acts are reduced and the effect of light irradiation is reduced essentially. That is, even in the case where light with a wavelength of 350 nm is delivered at 1×1013 photons/cm2·sec, a channel region of a transistor is formed using an oxide semiconductor, in which the absolute value of the amount of the variation in the threshold voltage is less than or equal to 0.65 V.

摘要： A logic circuit includes a thin film transistor having a channel formation region formed using an oxide semiconductor, and a capacitor having terminals one of which is brought into a floating state by turning off the thin film transistor. The oxide semiconductor has a hydrogen concentration of 5×1019 (atoms/cm3) or less and thus substantially serves as an insulator in a state where an electric field is not generated. Therefore, off-state current of a thin film transistor can be reduced, leading to suppressing the leakage of electric charge stored in a capacitor, through the thin film transistor. Accordingly, a malfunction of the logic circuit can be prevented. Further, the excessive amount of current which flows in the logic circuit can be reduced through the reduction of off-state current of the thin film transistor, resulting in low power consumption of the logic circuit.

摘要： A highly reliable semiconductor device having stable electric characteristics is provided by suppressing, in a transistor including an oxide semiconductor film, diffusion of indium into an insulating film in contact with the oxide semiconductor film and improving the characteristics of the interface between the oxide semiconductor film and the insulating film. In an oxide semiconductor film containing indium, the indium concentration at a surface is decreased, thereby preventing diffusion of indium into an insulating film on and in contact with the oxide semiconductor film. By decreasing the indium concentration at the surface of the oxide semiconductor film, a layer which does not substantially contain indium can be formed at the surface. By using this layer as part of the insulating film, the characteristics of the interface between the oxide semiconductor film and the insulating film in contact with the oxide semiconductor film are improved.
