High Performance Organic Field Effect Transistors: Improved Materials As Basis For Robust Processes (Printed Electronics Europe 2016)

Organic Field Effect Transistors for display backplanes and circuitry require materials that guarantee high performance and enable robust processes. To meet these needs, BASF is developing solution-processable organic semiconductors and matching photo-patternable dielectrics which are tailored to a variety of coating and printing processes. We present a market-ready material set giving field effect transistors with mobilities of 2cm²/Vs based on a scalable, highly homogenous process. Next generation materials demonstrate mobilities of to up to 4cm2/Vs. For process integration we showcase a simplified i-line photo-patterning process that reduces the number of steps compared to classical photolithography without loss of system performance.

BASF New Business is a subsidiary of BASF SE. We provide material system solutions to manufacture Organic Thin Film Transistors for backplanes of truly flexible displays, active matrices for sensors and paper-thin circuitry for e.g. smart packaging, labels, etc. Our portfolio includes ready-to-use inks of p- and n-type semiconductors, dielectrics and auxiliary materials as well as predefined ink packages.
