Provided are a vertical Schottky barrier diode using a two-dimensional layered semiconductor and a fabrication method thereof, the vertical Schottky barrier diode having excellent response characteristics in a high frequency region and capable of being directly fabricated from a material having a low melting point such as glass or plastic because its fabrication process is performed at a relatively low temperature. The vertical Schottky barrier diode includes: an ohmic contact layer formed of a metal; a two-dimensional layered semiconductor formed of two-dimensional transition metal dichalcogenides (TMDs) on one surface of the ohmic contact layer; a Schottky contact layer formed on one surface of the two-dimensional layered semiconductor; and a non-conductive layer formed on the other surface of the ohmic contact layer or one surface of the Schottky contact layer.
