METHOD FOR MANUFACTURING A THIN FILM TRANSISTOR USING SMALL MOLECULE AND POLYMER ORGANIC SEMICONDUCTOR BLENDS AND AN ORGANIC THIN FILM TRANSISTOR MANUFACTURED BY THE SAME, CAPABLE OF IMPROVING PERFORMANCE BY MAXIMIZING THE SIZE OF A SMALL MOLECULAR ORGANIC CRYSTAL

摘要

PURPOSE: A method for manufacturing a thin film transistor using small molecule and polymer organic semiconductor blends and an organic thin film transistor manufactured by the same are provided to minimize obstacles to form a large crystal of a small molecule on an organic semiconductor mixing film by coating the substrate with the small molecule and polymer organic semiconductor blends and reducing the temperature of a thermal process.;CONSTITUTION: A substrate is prepared. Source and drain electrodes are formed on the substrate. A small molecule and polymer organic semiconductor blend layer is formed on the source and drain electrodes. The substrate with a semiconductor layer is thermally processed. An organic insulation film layer is formed on the substrate which is thermally processed. A gate electrode is formed on the substrate with the organic insulation film layer.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Substrate provision; (BB) Source/drain electrode forming; (CC) Organic semiconductor blend layer forming; (DD) Organic semiconductor blend layer thermal processing; (EE) 40~60°C 30 min; (FF) Organic insulation film layer forming; (GG) Gate electrode forming
