Abstract:
1. A manufacturing method of an organic semiconductor device comprising a step of transferring an organic semiconductor layer to a gate insulation layer by a thermal transfer at a liquid crystal phase transition temperature of a liquid crystalline organic semiconductor material, and the step uses: an organic semiconductor layer-transferring substrate comprising a parting substrate having a parting property, and the organic semiconductor layer formed on the parting substrate and containing the liquid crystalline organic semiconductor material; and a substrate for forming an organic semiconductor device comprising a substrate, a gate electrode formed on the substrate, and the gate insulation layer formed to cover the gate electrode and having an alignment property which is capable of aligning the liquid crystalline organic semiconductor material on a surface of the gate insulation layer, wherein the organic semiconductor layer-transfer step further comprises steps of: a substrate-providing step of providing the organic semiconductor layer and the gate insulation layer so as they contact each other; a thermal transfer step of transferring the organic semiconductor layer to the gate insulation layer by heating the organic semiconductor layer to the liquid crystal phase transition temperature of the liquid crystalline organic semiconductor material; and a parting substrate-peeling step of peeling the parting substrate from the organic semiconductor layer-transferring substrate.
