    摘要: A semiconductor device which can operate at high speed and consumes a smaller amount of power is provided. In a semiconductor device including transistors each including an oxide semiconductor, the oxygen concentration of the oxide semiconductor film of the transistor having small current at negative gate voltage is different from that of the oxide semiconductor film of the transistor having high field-effect mobility and large on-state current. Typically, the oxygen concentration of the oxide semiconductor film of the transistor having high field-effect mobility and large on-state current is lower than that of the oxide semiconductor film of the transistor having small current at negative gate voltage.

    摘要: According to the present invention, a manufacturing device of a semiconductor device provided with a device for uniformly doping with an impurity element a large area substrate capable of multiple patterns for the purpose of mass-production is provided. The present invention has a feature that a cross section of an ion current is to be a linear shape or a rectangle, and the large area substrate is moved in a direction perpendicular to a longitudinal direction of the ion current while keeping the large area substrate inclined at a predetermined tilt angle θ to the ion current. In this invention, an incident angle of an ion beam is adjusted as changing the tile angle θ. By making the large area substrate inclined to a horizontal plane, the width of the longitudinal direction of the ion current can be shortened than the length of a side of the substrate.

    摘要: A thin film transistor includes, as a buffer layer, a semiconductor layer which contains nitrogen and includes crystal regions in an amorphous structure between a gate insulating layer and source and drain regions, at least on the source and drain regions side. As compared to a thin film transistor in which an amorphous semiconductor is included in a channel formation region, on-current of a thin film transistor can be increased. In addition, as compared to a thin film transistor in which a microcrystalline semiconductor is included in a channel formation region, off-current of a thin film transistor can be reduced.
