Towards Implementation of Logic Circuits Based on Intrinsically Reconfigurable Organic Transistors

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

Previously reported research achievements in that particulardomain also indicate that some of the organic semiconductor materials could beused for construction of organic field-effect transistors (OFET) that exhibit ratherpeculiar ability of ambipolar charge conduction. Fundamental electronic structures of such type also suggest theperspective of their utilization as the key building blocks for so calledmultifunctional logic elements or even more complex polymorphic circuits.

Inthis paper, main focus is given to the introduction of organic transistordevices with the ambipolar property that would allow to further increase theefficiency of multifunctional circuit design and synthesis techniques.Important aspect depicting the novelty of the proposed approach is primarilybased on the adoption of hybrid combination of the traditional siliconsubstrate with the deposition of suitable organic semiconductor layer. Inaddition, custom chip carrier platform was also developed for this purpose. Finally,the paper is concluded with review of the achieved results and suggestion offurther research directions.
