A method of fabricating an organic thin film transistor exhibiting excellent semiconductor performance by which an organic TFT can be formed continuously on a flexible base such as a polymer support through a simple coating process, and thus the fabrication cost can be reduced sharply, and an organic semiconductor layer thus formed has a high carrier mobility, In the method of fabricating an organic thin film transistor by forming a gate electrode, a gate insulation layer, an organic semiconductor layer, a source electrode and a drain electrode sequentially on a support, the organic semiconductor layer contains an organic semiconductor material having an exothermic point and an endothermic point in a differential scanning thermal analysis, and the organic semiconductor layer thus formed is heat-treated at a temperature not less than the exothermic point and less than the endothermic point.
