ORGANIC THIN FILM TRANSISTOR, METHOD FOR MANUFACTURING THE ORGANIC THIN FILM TRANSISTOR, AND ORGANIC SEMICONDUCTOR DEVICE

摘要

An organic semiconductor layer having a high positional accuracy is formed by a simple wet process by eliminating troubles due to static electricity. In a method for manufacturing an organic thin film transistor, the organic semiconductor layer is formed on a supporting body by applying an organic semiconductor solution wherein an organic semiconductor material is dissolved in an application solvent and drying the solution. The application solvent is composed of two or more types of solvents including a polar solvent having a dielectric constant of 7 or more but not more than 50.
