Organic materials to organic thin film transistor devices

Author(s): Shashi Pandya

Organic Thin Film Transistors (OTFT) technology is poised to be an important component in coming years in printed and hybrid electronics segment. This is because the OTFT technology platform enables manufacturing of high performance, ultra-thin, high definition display screens on flexible plastic substrates, particularly suitable for portable devices such as smartphones and tablets and the emerging market for wearable devices. NeuDrive have developed FlexOSTM – a proprietary organic semiconductor formulation based on soluble small molecules/high permittivity semiconductor binders as well as a novel organic thin film transistor form factor and fabrication process. FlexOSTM has world-leading mobility, stability and uniformity performance validated for flexible display backplanes. NeuDrive’s OTFT technology can be integrated with printing- based manufacturing processes to produce low-cost and large-area electronic transistor circuits on flexible circuits. The performance of the device largely depends on the materials used. The paper will discuss the challenges and achievements of new materials, their processing limits and the performance in fabricated OTFT carried out by NeuDrive.
