Abstract:
A process for fabricating an organic circuit, comprising the steps of:providing a substrate, the substrate optionally comprising a polymeric dielectric layer formed thereon;providing a solution comprising a solvent and an organic semiconductor compound;treating the substrate surface or the dielectric layer surface with a reagent that acts to bind groups onto the surface, wherein the bound groups decrease the wettability of the surface relative to the solution;applying the solution to the treated surface by a non-spinning technique, wherein the bound groups on the surface provide for a contact angle between the solution and the surface of at least 50.degree.; andevaporating the solvent to form an organic semiconductor film comprising a continuous area greater than 1 cm.sup.2 that exhibits a charge carrier mobility of at least about 10.sup.-4 cm.sup.2 V.sup.-1 s.sup.-1 at room temperature.
