Description

Nowadays, electronic circuits based on wide range of organic materials with semiconductor properties are still perceived as a somewhat unconventional design approach and fabrication technology. However, it could potentially deliver many significant advantages. Materials for organic electronics are typically lighter, flexible, easier to handle and less expensive in comparison with traditional inorganic materials used in electronics (e.g. copper and silicon used for conventional CMOS process).

Previously reported research achievements in that particular domain also indicate that some of the organic semiconductor materials could be used for construction of organic field-effect transistors (OFET) that exhibit rather peculiar ability of ambipolar charge conduction. Fundamental electronic structures of such type also suggest the perspective of their utilization as the key building blocks for so called multifunctional logic elements or even more complex polymorphic circuits.

For the purpose of demonstrating the properties of individual ambipolar transistors alongside the complete multifunctional circuits blocks there has been developed a hybrid platform based on LOFET3 substrate, which contains an essential electrode foundation (for transistors, inverters, registers and other circuit elements) fabricated using so called lift-off technique. In this case, after the removal of protective resist coating from the surface of LOFET 3 substrate, it was only necessary to deposit by means of using suitable technique, e.g. PVD process or spin-coating, the active organic channel layer and subsequently cover it with a protective material (e.g. PMMA).
