1. A method for fabricating a device using an oxide semiconductor, the method comprising:

  • forming an oxide semiconductor on a substrate; and

    changing a conductivity of a predetermined region of the oxide semiconductor by irradiating the predetermined region with an energy ray,wherein the changing of the conductivity of the predetermined region is performed to increase the conductivity of the predetermined region by irradiating the predetermined region with light having a wavelength equivalent to or greater than a band-gap energy of the oxide semiconductor.
