<p>PURPOSE:To prevent element characteristics from becoming asymmetric and to make an electric characteristic stable by laminating an organic conductor layer, an organic insulator or semiconductor layer and an organic conductor layer on a substrate electrode. CONSTITUTION:An electrode 2 is formed on a glass substrate 1 and employed as an anode. A polypyrrole conductor layer 3 wherein copper phthalocyanine tetrasulfate ions are taken as a dopant is formed on the electrode, and a conductor layer 4 of polypyrolle wherein forofluoride ions are taken as the dopant is laminated thereon. Moreover, a polypyrrole conductor layer 5 wherein copper phthalocyanine tetrasulfate sodium ions are taken as the dopant is laminated thereon, a reverse bias voltage is impressed thereon to remove only the borofluoride ions, and thereby the layer 4 is turned to be an organic semiconductor layer 4. In this way, an element can be prevented from becoming asymmetric, no damage is given to an organic insulator or a semiconductor in an intermediate layer since any metal or metal oxide film is not used for an upper electrode, and thus a stable nonlinear two-terminal element being free from short-circuit can be constructed.</p> |
