Using soluble polymers as active and insulating layers we report on fast and stable integrated circuits based on p-type organic transistors. On flexible polyester film substrates single field-effect transistors and ring oscillators with frequencies above 190 kHz and propagation stage delays below 0.4 µs were fabricated with regioregular poly(3-alkylthiophene). Even without encapsulation the devices show a very stable performance while stored and measured under ambient and extreme conditions [1]. Furthermore we report on organic rectifiers based on polymer rectifier diodes and polymer capacitors. Our results show the potential of integrated plastic circuits based on soluble polymers to be suitable for inexpensive high volume electronic applications (e.g. RFID-tags).
