    • PURPOSE: An RLC(Resistance Inductance Capacitance) circuit using a micro carbon structure is provided to form a micro circuit with a new concept having a mixed RLC by forming a micro carbon structure including a carbon nano tube on a surface of an inorganic substance carrier and arranging the micro carbon structure. CONSTITUTION: Ni is soaked into gamma alumina. The mixture of Ni and gamma alumina is calcined under temperature of 900 degrees centigrade. A gamma alumina bead(1/8inx1/8in) is added into a reactor formed with quartz. Hydrogen and methanol of a ratio of 1 to 1 are added into the reactor. The reactor is heated by a heater. A vapor deposition process of carbon is performed under temperature of 1000 degrees centigrade. An electrical characteristic is measured after the vapor deposition process of carbon is performed during 6 hours. One bead of alumina is acted as an inductive material by applying a single pulse.
