Abstract

Rapid development of flexible electronics requires thin film transistor (TFT) to have features of low power consumption

good bending resistance and ability to be fabricated at low temperature. Gate insulator is one of the key materials in TFT device. Organic gate insulator prepared by solution method has the advantages of low cost

strong flexibility and is suitable for large area processing. In this paper

polyvinylpyrrolidone (PVP) dielectric film was achieved by inkjet printing process. The composition difference of printed PVP films with different annealing temperature was analyzed by XPS

and leakage current

capacitance and transfer characteristic of PVP devices were obtained by semiconductor analyzer. TFT device with PVP film annealed at 200 ℃ showed leakage current density ≤ 10
