MANUFACTURING PROCESS OF ORGANIC CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing process of an organic circuit. SOLUTION: An organic semiconductor thin film is formed, for instance, through a solution forming manner where a solution which contains an organic semiconductor material and solvent is fed on a board 18, and the solvent is evaporated for the formation of an organic semiconductor thin film. The surface characteristics of a board, organic semiconductor material, and process parameters are so selected as to form required nucleuses and to grow crystals. The obtained organic semiconductor thin film includes a continuous region whose area is larger than 1 cm2 and where carrier mobility is comparatively high or about 10-4 cm2V-1s-1 at a room temperature.
