With the goal to study complex organic thin film transistor (OTFT) architecture, thin films of semiconductors and of metallic materials have been laser printed. The n-type copper hexa deca fluoro phthalocyanine (F16CuPc) and p-type copper phthalocyanine (CuPc) semiconductors have been used to form the active layers. The materials have been successively transferred onto a receiver substrate by laser pulses in the picosecond regime. The latter substrate has formed the gate and the dielectric of the transistor. The three materials have been then combined in a multilayer stack prepared by the successive depositions of the materials by thermal evaporation under vacuum and then laser have been printed in a single step.
