METHOD OF MANUFACTURING ORGANIC THIN FILM TRANSISTOR

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an organic thin film transistor which has a sufficient carrier mobility and is easily manufactured with less variations. SOLUTION: This method comprises a step of preparing a second member where a first member includes a photothermal conversion layer having a thermal bonding strength to an organic semiconductor layer is smaller than a thermal bonding strength to the first substrate, and an amorphous-state organic semiconductor having a property of being crystallized when heated and melted or sublimated and a second member includes an organic semiconductor layer which connects at least source and drain electrodes provided to a second substrate and which is crystallized and formed when melted or sublimated and which has a bonding strength larger than the bonding strength between the organic semiconductor layer and the photothermal conversion layer; a step of stacking the first and second members; a step of irradiating light to the photothermal conversion layer; a step of separating the first member from the second member.
