Abstract
Disclosed is a method of manufacturing a multilayered thin film including a crystalline small molecular organic semiconductor layer and an insulating polymer layer for use in an organic thin film transistor through phase separation and annealing. The method includes applying a blend solution of organic semiconductor and insulating polymer on a substrate thus forming a vertically phase-separated thin film, which is then annealed so that the organic semiconductor contained in the insulating polymer layer is crystallized while being transferred to the surface layer. A high-performance organic thin film transistor fabricated using the same is also provided. The multilayered thin film in which the crystalline organic semiconductor layer is located on the insulating polymer layer through transfer and crystallization of the organic semiconductor can be used to fabricate the high-performance organic thin film transistor.
