Photolithography in the service of organic electronics — •Alex Zakhidov, Hans Kleemann, Björn Lüssem, and Karl Leo — Institut für Angewandte Photophysik, Technische Universität Dresden, Germany

Organic electronic materials have attracted interest due to their facile processing that creates tantalizing prospects for new fabrication techniques such as ink-jet printing to deliver materials only where needed. Photolithography, the gold standard process of the microelectronics industry, has received relatively little attention for the patterning of organics. The recent commercialization of organic light emitting diodes (OLEDs) in flat panel displays, however, involved their integration with silicon circuitry. Similar heterogeneous integration is envisioned in other emerging applications such as large area electronics. The ability to use photolithography to pattern all layers will enable simpler fabrication using already existing infrastructure, as well as the realization of device architectures currently not achievable using separate patterning techniques for organic and inorganic layers.
