Abstract

Method of manufacturing a semiconducting organic laminated structure, for use in an electronic circuit, in particular a logic and/or memory circuit, wherein a substrate is coated with a solution or dispersion containing a small proportion of an organic composite and having a certain wet-layer thickness, which by drying is converted into an organic thin layer with semiconducting properties that adheres to the substrate and has a dry-layer thickness substantially less than the wet-layer thickness, in particular by an order of magnitude or more, the drying being accomplished by brief irradiation with electromagnetic radiation that has its main effective component in the near-infrared range, in particular in the region between 0.8 and 1.5 μm.
