METHOD FOR MANUFACTURING ORGANIC THIN FILM TRANSISTOR, AND ORGANIC THIN FILM TRANSISTOR

摘要

Provided are an organic TFT manufacturing method by which ink leakage into an unnecessary region can be suppressed and excellent characteristics and high reliability can be obtained, and an organic TFT.  The organic TFT manufacturing method has: a step of forming a source electrode and a drain electrode on a base member; a step of forming a bank layer, which has openings on a channel region between the source electrode and the drain electrode and on a predetermined region of the base member and a groove surrounding the opening on the circumference of the opening on the predetermined region; and a step of forming the organic semiconductor film by dropping an organic semiconductor solution to the opening on the bank layer formed on the channel region.
