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).
