Micro- and nanopatterning techniques for organic electronic and optoelectronic systems

The use of organic compounds as active materials in electronic and optoelectronic devices opens the door to a large number of efficient and potentially low-cost methods for fabricating useful, and, in some cases, complicated structures that are inaccessible by conventional methods using conventional semiconductors. The techniques available for processing and patterning organic materials move far beyond the lithographic methods that govern inorganic devices. This paper discusses the use of a range of processes that are unique to organic materials, including embossing, imprint lithography and capillary molding and printing, using a range of different stamping approaches.
