A transistor that uses an oxide semiconductor film and has excellent on-state characteristics is provided. A semiconductor device capable of high-speed operation is provided. In a transistor that uses an oxide semiconductor film, the oxide semiconductor film is subjected to nitrogen plasma treatment.

The oxynitride region has lower resistance than the other region of the oxide semiconductor film. In addition, the oxynitride region is unlikely to form high-resistance metal oxide at the interface with the contacting metal film.

    Abstract: A miniaturized semiconductor device in which an increase in power consumption is suppressed and a method for manufacturing the semiconductor device are provided. A highly reliable semiconductor device having stable electric characteristics and a method for manufacturing the semiconductor device are provided. An oxide semiconductor film is irradiated with ions accelerated by an electric field in order to reduce the average surface roughness of a surface of the oxide semiconductor film. Consequently, an increase in the leakage current and power consumption of a transistor can be suppressed. Moreover, by performing heat treatment so that the oxide semiconductor film includes a crystal having a c-axis substantially perpendicular to the surface of the oxide semiconductor film, a change in electric characteristics of the oxide semiconductor film due to irradiation with visible light or ultraviolet light can be suppressed.
