Fully printed integrated circuits from solution processable polymers

The discovery of (semi) conducting polymers opened a route to the fabrication of microelectronics by printing. We designed structural and electrical properties of printed polymeric thin films and multilayers to set up field-effect transistors. The polymeric transistors are fully logic capable as is proven by persistent operation of an integrated ring-oscillator circuit. Solution processing of the polymers in printing is completely done under ambient conditions resulting in stable operation of the printed transistors and microcircuits.
