Fast organic thin-film transistor circuits

IEEE Electron Device Letters, 1999

We have fabricated organic thin-film transistors and integrated circuits using pentacene as the active material. Devices were fabricated on glass substrates using low-temperature ion-beam sputtered silicon dioxide as the gate dielectric and a double-layer photoresist process to isolate devices. These transistors have carrier mobility near 0.5 cm2/V-s and on/off current ratio larger than 10/sup 7/. Using a level-shifting design that ...


Pentacene-based organic thin-film transistors

IEEE Transactions on Electron Devices, 1997

Organic thin-film transistors using the fused-ring polycyclic aromatic hydrocarbon pentacene as the active electronic material have shown mobility as large as 0.7 cm/sup 2//V-s and on/off current ratio larger than 10/sup 8/; both values are comparable to hydrogenated amorphous silicon devices. On the other hand, these and most other organic TFT's have an undesirably large subthreshold slope. We show here ...

  • Fast organic thin-film transistor circuits

    We have fabricated organic thin-film transistors and integrated circuits using pentacene as the active material. Devices were fabricated on glass substrates using low-temperature ion-beam sputtered silicon dioxide as the gate dielectric and a double-layer photoresist process to isolate devices. These transistors have carrier mobility near 0.5 cm2/V-s and on/off current ratio larger than 10/sup 7/. Using a level-shifting design that allows circuits to operate over a wide range of threshold voltages, we have fabricated ring oscillators with propagation delay below 75 μs per stage, limited by the level-shifting circuitry. When driven directly, inverters without level shifting show submicrosecond rise and fall time constants.

  • Pentacene-based organic thin-film transistors

    Organic thin-film transistors using the fused-ring polycyclic aromatic hydrocarbon pentacene as the active electronic material have shown mobility as large as 0.7 cm/sup 2//V-s and on/off current ratio larger than 10/sup 8/; both values are comparable to hydrogenated amorphous silicon devices. On the other hand, these and most other organic TFT's have an undesirably large subthreshold slope. We show here that the large subthreshold slope typically observed is not an intrinsic property of the organic semiconducting material and that devices with subthreshold slope similar to amorphous silicon devices are possible.

  • Organic thin-film transistors for organic light-emitting flat-panel display backplanes

    The performance of organic thin-film transistors (OTFTs) has improved significantly in the last several years and it now appears likely that they will find application in low-cost large-area electronic applications. Active- matrix displays are of special interest and integration of OTFTs with organic light-emitting devices (OLEDs) in all-organic displays is particularly attractive. The device requirements for active-matrix OLED displays are very similar to those of active-matrix liquid crystal displays (AMLCDs) and can be satisfied with OTFTs fabricated using stacked pentacene active layers. Such devices have demonstrated field-effect mobility near 1.5 cm/sup 2//V/spl middot/s, on/off current ratio near 10/sup 8/, near-zero threshold voltage, and subthreshold slope less than 1.6 V/decade. These characteristics are similar to those obtained with hydrogenated amorphous silicon (a-Si:H) devices and such devices would allow the use of polymeric substrates with advantages in weight, ruggedness, and cost compared to glass substrates currently used with a-Si:H devices in AMLCDs.

  • High resolution full color liquid crystal display driven by solution-processed organic thin film transistors

    We have fabricated a solution processed high resolution (15.0 inch diagonal sized SXGA, 110ppi) organic thin film transistor array to drive the liquid crystal display, where the whole layers except an electrode were formed by organic materials using solution process. The TFT in the array exhibited an average field effect mobility of 0.2~0.3 cm<sup>2</sup>/Vs, an on/off current ratio of 10<sup>6</sup>, and obtained good uniformity as well as high mobility of OTFT performance.

  • Solvent Effect on the Electrical Properties of Triisopropylsilylethynyl (TIPS) Pentacene Organic Thin-Film Transistors

    We investigated the electrical properties of triisopropylsilylethynyl (TIPS) pentacene organic thin-film transistor (OTFT) depending on solvent type. TIPS pentacene was spin coated by using chlorobenzene, p-xylene, chloroform, and toluene as solvents. A broad spectrum of electrical properties was affected by the solvent choice. Fabricated OTFT with chlorobenzene shows field-effect mobility of 1.0 × 1<sup>0-2</sup> cm<sup>2</sup>/V · s, on/off ratio of 4.3 × 10<sup>3</sup>, and threshold voltage of 5.5 V. In contrast, with chloroform, the mobility is 5.8 × 10<sup>-7</sup> cm<sup>2</sup>/V · s, on/off ratio of 1.1 × 10<sup>2</sup>, and threshold voltage of 1.7 V. Further investigation by measurement of the grain size of TIPS thin films by atomic force microscopy (AFM) and X-ray diffraction spectroscopy showed that solvents with higher boiling points resulted in larger grain sizes and improved crystallinity. The higher performance electrical characteristics are explained by large grain size and high crystallinity of the TIPS pentacene layer in films spin coated with higher boiling point such as chlorobenzene.

  • Heterojunction organic thin-film transistors

    We have developed a unique organic transistor structure which enables us to realize both p-channel and n-channel operation in a single device. This device also demonstrates the applicability of heterojunction concepts to organic semiconductors. The active material consists of two layers: the first layer, typically 10-20 nm thick, is made up of /spl alpha/-hexathienylene (/spl alpha/-6T), a thiophene oligomer which exhibits good p-channel operation. The second active material is C/sub 60/ and is about 20-30 nm thick. The energy levels of the occupied and unoccupied molecular orbitals of /spl alpha/-6T and C/sub 60/ are such that when the gate is biased negatively with respect to the source, the p-channel material is filled with holes and when the gate is biased positively, the n-channel material (C/sub 60/) is filled with electrons. A detailed analysis of the transistor characteristics provides important insights into transport in organic materials and is discussed.

  • Physics and applications of low-dimensional organic thin-film transistors

    We describe the electrical characteristics of thin film transistors with active layers made with /spl alpha/-hexathienylene. The on-conductance in these transistors is two-dimensional. The mobility of field induced carriers and the shape of the current-voltage characteristics depend on the channel length. With interdigitated source-drain regions we have achieved on/off ratios of more than 10/sup 5/.<<ETX>>
