GAS SENSOR USING CARBON NANO-TUBE AND METHOD FOR MANUFACTURING THE SAME FOR FABRICATING GAS SENSOR BY DIRECTLY GROWING CARBON NANO-TUBE ON ELECTRODE THROUGH CHEMICAL VAPOR PROCESS

摘要

PURPOSE: A gas sensor using carbon nano-tube and a method for manufacturing the same are provided to simplify a manufacturing process of the carbon nano-tube by adjusting the density of the carbon nano-tube. CONSTITUTION: A substrate is given in order to manufacture a gas sensor using a carbon nano-tube. The substrate has a predetermined electrode pattern formed thereon. The material of the carbon nano-tube is provided. Solvent is provided in order to spray the carbon nano-tube. An ultrasonic process is performed by adding the carbon nano-tube to the solvent. The carbon nano-tube formed on the upper layer of a solution is retrieved after rotating the solution over a predetermined rotation number. A contact resistance between electrodes of the carbon nano-tube is reduced through a thermal treatment after the distribution step.
