METHOD FOR FABRICATING ZNO NANOWIRE USING METAL MASKING AND THE ZNO NANOWIRE MEMBER FABRICATED FROM THE SAME

摘要

PURPOSE: A manufacturing method of zinc oxide nano-wires using metal masking and a zinc oxide nano-wire material manufactured by the method are provided to control density of growing zinc oxide nano-wires by forming metallic mask layer on a catalyst layer without a light exposure process. CONSTITUTION: A manufacturing method of zinc oxide nano-wires using metal masking comprises the following steps: preparing a substrate(10); forming a catalyst layer(20) of zinc oxide material on the substrate; forming a mask layer(30) having a plurality of growth holes(33) through a thermal process; and growing zinc oxide nano-wires(40) based on the catalyst layer part which is exposed to the plurality of growth holes. The metallic mask layer formation step comprises the following steps: forming a coating layer with 20-30 nano meters thickness by spreading aqueous solution including the metal nano-particles on the catalyst layer; and forming the metallic mask layer by heat treating the coating layer at 150-700 deg. Celsius.
