Progress in stability, mobility and processability of conjugated polymers has triggered research on their use as the active semiconductor in thin film field-effect transistors. The main advantages of application of solution processable semiconducting polymers are their easy processing, e. spin coating and ink-jet printing, without a temperature hierarchy, and their mechanical flexibility. Applications are foreseen in the field of large area electronics, where numerous devices are required on low-cost substrates such as glass or plastic. This presentation will start with a technology for fabrication of integrated circuits for contactless identification and product tagging. We demonstrate RFID tags manufactured with organic transistors that are energized and read out using a 13. MHz carrier, the de-facto standard for item level RF identification. The tags store two different codes, enabling for the first time identification of objects with organic transponders at this frequency. In addiction we present functional 64 bit RFID tags, the most complex organic transponders reported to date. Remaining challenges are, apart from process technology, the use of unipolar logic and of hard wired memory elements. Possible solutions such as ambipolar transistors and complementary-like circuits, and ferroelectric field-effect transitors will be discussed. Finally, spin-off's of the technology developed such as rollable displays will be presented.
