We report high-performance organic TFTs with short channel length (L) of 6 µm. The OTFTs employ a bottom-gate, bottom-contact structure, with all layers patterned by conventional photolithographic methods. A field effect mobility of ~0.45 cm2/V∙s, and the on-to-off current ratio of ~106 were obtained in the fabricated p-channel OTFTs. The short channel OTFT with excellent performance is promising for flexible, high-resolution displays.
