Abstract
Provided are a semiconductor technique, and more particularly, to a variable resistor, a non-volatile memory device using the same, and a method of fabricating the same. The variable resistor may include a first electrode including titanium (Ti); a second electrode for forming a Schottky barrier; and a stacked structure including an oxygen-deficient hafnium oxide film (HfO, 0<x<2) between the first electrode and the second electrode, an oxygen-deficient titanium oxide (TiO) film between the oxygen-deficient hafnium oxide film and the first electrode, and a stoichiometric tantalum oxide (TaO) film between the oxygen-deficient hafnium oxide film and the second electrode.
