Process for fabricating organic circuits
 An organic semiconductor film is fabricated by applying a solution containing an organic semiconductor material and a solvent to a substrate, e.g., by solution casting, and evaporating the solvent. The characteristics of the substrate surface, the organic semiconductor material, and the process parameters are selected to provide desirable nucleation and crystal growth. The resultant organic semiconductor film contains a large area, e.g., a continuous area greater than 1 cm.sup.2, that exhibits a relatively high charge carrier mobility of at least about 10.sup.-4 cm.sup.2 V.sup.- s.sup.-1 at room temperature.
