NOVELTY - An organic semiconductor thin film is manufactured by applying a precursor solution comprising an aromatic enediyne derivative and organic solvent to a substrate to form a coating film, and treating the coating film at a treatment temperature and for a treatment period to induce crosslinking of the aromatic enediyne derivatives to form the organic semiconductor thin film.    USE - Method of manufacturing an organic semiconductor thin film used in making a semiconductor device including thin film transistors (TFTs), electroluminescent devices, display devices, solar cells or memory devices (claimed).    ADVANTAGE - The method can provide organic semiconductor thin films exhibiting improved chemical and/or electrical stability for fabricating devices having improved functionality and/or reliability.    DETAILED DESCRIPTION - Manufacturing an organic semiconductor thin film comprises applying a precursor solution comprising an aromatic enediyne derivative having a structure of formula (I) and organic solvent to a substrate to form a coating film, and treating the coating film at a treatment temperature and for a treatment period to induce crosslinking of the aromatic enediyne derivatives to form the organic semiconductor thin film.    X 1-X 3, A 1, A 2=optionally substituted 3-30C arylene groups or optionally substituted 2-30C heteroarylene groups;    R 1-R 4=halo, NO 2group, amino group, CN group, -SiR 1R 2R 3, or 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 1-20C alkoxy, 6-20C arylalkyl, 6-30C aryloxy, 2-30C heteroaryloxy, 1-20C heteroalkyl, or 2-30C heteroarylalkyl (all optionally substituted);    R 1-R 3=H or 1-10C alkyl;    a-c=0-10; or    a+b+c=greater than 0.    An INDEPENDENT CLAIM is included for a method of making a semiconductor device having an organic semiconductor thin film, comprising:    (A) applying a precursor solution comprising an aromatic enediyne derivative (I);    (B) treating the coating film at a treatment temperature and period to induce crosslinking of the aromatic enediyne derivatives to form the organic semiconductor thin film; and    (C) configuring the organic semiconductor thin film to serve as a carrier transport layer.
