Small-channel organic thin-film transistors OTFTs are an essential component of microelectronic devices. With the advent of flexible electronics, the fabrication of OTFTs still faces numerous hurdles in the realization of highly-functional, devices of commercial value. Herein, a concise and efficient procedure is proposed for the fabrication of flexible, small-channel organic thin-film transistor OTFT arrays on large-area substrates that circumvents the use of photolithography.

Printable organic thin-film transistor O-TFT is one of the most recognized technical issues nowadays. Our recent progress on the formation of organic-inorganic hybrid thin films consists of polymethylsilsesquioxane PMSQ , and its applications for the gate-insulating layer of O-TFTs are introduced in this paper. The PMSQ film contains no mobile ionic impurities, and this is also important property for the practical use for the gate-insulating materials. Moreover, by the modification of PMSQ, further functionalities, such as surface hydrophobicity, high permittivity that allows low driving voltage, and photocurability that allows photolithography, could be appended to the PMSQ gate-insulating layers. Organic thin-film transistor O-TFT is an indispensable component in the development of large-area, flexible, and low-cost electronic devices, such as paper-like displays, radio frequency identification tags, and high-performance sensors.

Inkjet printing, known as digital writing technique, can directly deposit functional materials to form pattern onto substrate. This paper provides an overview of inkjet printing technologies for flexible electronics. Firstly, we highlight materials challenges in implementing flexible devices into practical application, especially for inkjet printing process. Thirdly, the related equipments on inkjet printing are shown. Finally, challenges for its future development are also discussed.
Fabrication of oxide thin film transistor TFT arrays by inkjet printing with small spacing was investigated, aiming at printing high resolution display backplanes. Two processes are involved during the printing and drying of oxide ink drops; the initial ink drop spreads to a large size upon landing on a substrate and then shrinks to a small size after the solvent dries out. The spreading of the ink drop determines how close two ink drops can be placed and the shrinkage of the ink drop after drying determines the final thickness of the printed dot. However, too much shrinking caused random movement of the ink drops and an increase of oxide layer thickness, both of which are detrimental to the performance of printed TFTs. To overcome these problems, the ink viscosity was adjusted by adding polyvinylpyrrolidone PVP to the ink.

Printing technologies for thin-film transistors TFTs have recently attracted much interest owing to their eco-friendliness, direct patterning, low cost, and roll-to-roll manufacturing processes. Lower production costs could result if electrodes fabricated by vacuum processes could be replaced by inkjet printing. To the best of our knowledge, this is a major improvement for bottom-gate top-contact a-IGZO TFTs with directly printed silver electrodes on a substrate with no pretreatment.

In other words, devices should be implemented on substrates other than limited rigid silicon or glass, and miniaturized even at additional cost. Therefore, a variety of functional materials focusing on semiconductors have been extensively explored for realizing competitive flexible TFTs, including traditional silicon, 9 - 11 organics, 12 - 17 oxides, 18 - 21 carbon nanotubes CNTs22 - 26 and emerging 2D materials.
- Она встряхнула волосами и подмигнула. - Может быть, все-таки скажете что-нибудь. Что помогло бы мне? - сказал Беккер. Росио покачала головой: - Это. Но вам ее не найти. Севилья - город большой и очень обманчивый. - Я постараюсь.
