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.
