TRANSIENT PULSE FILTER MANUFACTURING METHOD USING ANODIC ALUMINUM OXIDE AND THE TRANSIENT PULSE FILTER

PURPOSE: A transient pulse filter manufacturing method using an anodic aluminum oxide and a transient pulse filter is provided to control the trigger voltage, the clamp voltage, and the leakage current etc by controlling the energy barrier thickness between the conductive materials. CONSTITUTION: An aluminum thin film layer is formed on the top of the insulator substrate(100). An aluminum oxide thin film layer(300) formed with a pore oxidized with the anodizing is formed. The metal material is deposited on the top of the aluminum oxide thin film layer in order to fill the hole. A nanorod(400) is formed inside the aluminum oxide thin film layer by eliminating the deposited metal material except for the hole. An inner electrode(500) is formed on the upper part of the aluminum oxide thin film layer in which a nanorod is formed. A passivation layer(600) is formed on the output upper part. An outer electrode(700) is formed on both sides of the substrate on which the passivation layer is formed.
