Abstract:
1. A method of manufacturing an instant pulse filter using anodic oxidation, comprising: a first step for forming an aluminum thin film layer over an insulator substrate; a second step for forming an aluminum oxide thin film layer having a pore by oxidizing the aluminum thin film layer by means of an anodic oxidation; a third step for depositing a metallic material over the aluminum oxide thin film layer for filling the pore; a fourth step for forming a nano rod in the interior of the aluminum oxide thin film layer by eliminating the deposited metallic material except the inside of the pore; a fifth step for forming an internal electrode over the aluminum oxide thin film layer having the nano rod; a sixth step for forming a protective film layer over the aluminum oxide thin film layer and the internal electrode from the external environment in order to protect the aluminum oxide thin film layer and the internal electrode from the external environment; and a seventh step for forming an external electrode on both sides of the substrate on which the protective film layer is formed.
