Abstract We report printed single and dual-gate organic thin film transistors (OTFTs) and PMOS inverters fabricated on 125 µm-thick flexible polyethylene naphthalate (PEN) substrate. All the electrodes (gate, source, and drain) are inkjet-printed, while the parylene dielectric is formed by chemical vapor deposition. A dispenser system is used to print the active channel material using a blend of 2,7-dihexyl-dithieno[2,3-d;2',3'-d']benzo[1,2-b;4,5-b']dithiophene (DTBDT-C6) and polystyrene (PS) in tetralin solvent, which gives highest mobility of 0.43 cm2/Vs. Dual-gate OTFTs are characterized by keeping the other gate electrode either in grounded or floating state. Floating gate electrode devices shows higher apparent mobility and current ratio due to additional capacitance of the parylene dielectric. PMOS inverter circuits are characterized in terms of gain, trip point and noise margin values calculated from the voltage transfer characteristics (VTC). Applied top gate voltage on the load OTFT control the conductivity or threshold voltage (VTh) of the bottom TFT and shift the trip point towards the middle of the VTC curve, and hence increase the noise margin.
