METHOD FOR SELECTIVE GROWTH OF METAL OXIDE NANO MATERIAL USING MICRO HEATER AND GAS SENSOR USING THE METHOD

摘要

A method for selectively depositing a metal oxide nano material and a gas sensor using the same are provided to improve crystallization through a rapid thermal process by using a micro heater and to remove the moisture attached on the surface of a nano line. A substrate removing a central region is provided. A membrane(20) is formed in an upper part of the substrate. A micro-heater electrode(40) is formed in the upper part of the membrane of the central region. An insulating layer(30) covering the micro heater is formed in the upper part of the membrane. A sensing electrode(50) is formed in the upper part of the insulating layer of the micro heater electrode part. The metal oxide nano material is deposited in an upper part of the sensing electrode.
