Photocurable Organic Gate Insulator for the Fabrication of High‐Field Effect Mobility Organic Transistors by Low Temperature and Solution Processing

A new organic gate insulator in OTFT devices, which satisfies the requirements for the fabrication of a practical TFT array, such as a good chemical resistance, a low moisture uptake, a low temperature process, and a good film surface smoothness, is introduced. Since this gate insulator film is formed by photo-curing after spincasting on the top of the gate electrode, the process does not require high temperatures.
