Simple Bar-Coating Process for Large-Area, High-Performance Organic Field-Effect Transistors and Ambipolar CMOS Integrated Circuits |
초록 |
We report a large-area, simple wire-bar–coating process as a suitable method for deposition of conjugated and insulating polymer films in OFET arrays and complementary ICs. The highly crystalline polymer semiconductor, PTVPhI-Eh, showed better crystalline morphology and the amorphous polymer semiconductor, (MEH-PPV) or PMMA, exhibited smoother film morphology when applied via the bar-coating process than by the spin-coating process. The best bar-coated OFETs with DPPT-TT showed a charge carrier mobility as high as 2.83 cm^2/Vs and excellent device-to-device performance uniformity with standard deviation of 0.05~0.06 in 4 inch transistor arrays. Finally, we fabricated bar-coated ambipolar CMOS inverters (voltage gain >40) and ring oscillators (ROs) (oscillation frequency (fosc) of ~25 KHz) with a PTVPhI-Eh and CsF interlayer. |
