Abstract

We fabricated an organic thin-film transistor (OTFT) using an all-step solution process. The printed layers, in which the electrode (silver), dielectric layer (BaTiO3-PMMA), source-drain layer, and semiconductor 6, 13-Bis(triisopropylsilylethynyl)pentacene(TIPS-pentacene), were optimized using roll-to-roll, an inkjet printer, and drop-casting. After coating the source-drain layer, we applied ultraviolet (UV)-ozone and self-assembled monolayer (SAM) treatments to the composite layer. The OTFTs treated with the UV-ozone and SAM treatments were found to exhibit excellent performance and good properties in comparison to silicon-based OTFTs.
