    摘要: The specification describes thin film transistor integrated circuits wherein the TFT devices are field effect transistors with inverted structures. The interconnect levels are produced prior to the formation of the transistors. This structure leads to added flexibility in processing. The inverted structure is a result of removing the constraints in traditional semiconductor field effect device manufacture that are imposed by the necessity of starting the device fabrication with the single crystal semiconductor active material. In the inverted structure the active material, preferably an organic semiconductor, is formed last in the fabrication sequence. In a preferred embodiment the inverted TFT devices are formed on a flexible printed circuit substrate.

    摘要: A process for fabricating thin film transistors in which the active layer is an organic semiconducting material with a carrier mobility greater than 10.sup.-3 cm.sup.2 /Vs and a conductivity less than about 10.sup.-6 S/cm at 20.degree. C. is disclosed. The organic semiconducting material is a regioregular (3-alkylthiophene) polymer. The organic semiconducting films are formed by applying a solution of the regioregular polymer and a solvent over the substrate. The poly (3-alkylthiophene) films have a preferred orientation in which the thiophene chains has a planar stacking so the polymer backbone is generally parallel to the substrate surface.
