Abstract

Fabrication of thin film transistors (TFT's) for display applications by IJ printing involves many individual but interrelated processes from the design of organic semiconductor materials (OSCs), development of stable formulations that can be jetted reliably, the design of patterned substrates together with electrodes and other structures, pre and post treatment processes to ensure correct semiconductor and dielectric layer formation together with optimization of the deposition and drying process. Each of these steps has to be designed to fit the complete manufacturing process, independently developed and then optimized for the total device.In this paper we describe some aspects of this development cycle leading to commercially available ink jet printable organic semiconductor and dielectric inks using polymers and small molecules for TFT fabrication in displays and other device applications including:What is required from OSC materials and processes?How can we IJ print and process OSC's?Examples of IJ printed TFT performance we obtain.
