Low Temperature OFET (Organic Field Effect Transistor) Fabrication by Metal Nanoparticle Imprinting

The low temperature fabrication of OFET (organic field effect transistor) is presented in this paper. PDMS imprinting mold was used to pattern gold nano-particles suspended in Alpha-Terpineol solvent. After imprinting, nanoparticles was dried and then sintered at plastic compatible low temperature. Finally, air stable semiconductor polymer (modified polythiophene) in dichlorobenzene (o-DCB) solution to fabricate OFETs on flexible polymer substrates. The performance of the transistors were characterized and discussed.
