Polymer transistor circuits offer new opportunities for the controlled manufacturing of
active electronic circuits by a combination of solution processing and direct printing.
Control over the microscopic morphology of the polymer semiconductor is obtained by
making use of self-organisation mechanisms, such as liquid-crystalline phase behaviour.
Accurate definition of devices and integrated circuit components on a mesoscopic scale is
achieved by high resolution printing techniques such as surface energy-assisted inkjet
printing. These solution-based self-assembly techniques provide a new approach for
controlled fabrication of organic electronic devices with critical feature size approaching
molecular dimensions.
