This book was released on 2012 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deals with the development of vertical thin film transistors (VTFTs) via the fabrication processes and the analysis of the electrical characteristics. The low-temperature (T ≤ 600°C) polycrystalline silicon technology is adopted in the fabrication processes. The first step of the work consists in the fabrication and characterization of VTFTs obtained by rotating the lateral thin film transistors (LTFTs) 90°. The feasibility of VTFTs fabrication is validated with an ION/IOFF ratio of about 103, and it is analyzed that the large overlapping area between source and drain leads to a large off-current IOFF. The second step of the work lies in the partial suppression of the large overlapping area, and therefore, an ION/IOFF ratio of almost 105 is obtained. The third step of the work deals with the proposal of a new VTFT structure that absolutely eliminates the overlapping area. Different improvements have been made on this new VTFT structure, especially by optimization of the following parameters: the active layer thickness, type and thickness of the barrier layer, and the geometric dimension. The optimized transistor highlights an ION/IOFF ratio of higher than 105 with a reduced off-current IOFF, high stability and good reproducibility. P and N-type VTFTs have also been fabricated and showed symmetrical electrical characteristics; they are thus suitable for CMOS-like VTFT applications.

Available in PDF, EPUB and Kindle. Book excerpt: Transparent flexible electronics is an emerging technology which makes use of wide band gap semiconductors that can be processed at low temperatures on glass or plastic substrates. Electronic systems that cover large area and curved surfaces together with transparency bring the possibility of numerous applications that are outside the scope of rigid wafer based electronics. Flexible electronics, electronic textiles, a wearable wellness system, and sensory skin are some of the applications of flexible electronics. The key factor in the realization of transparent electronics is the development of high performance fully transparent thin film transistors. Thin film transistors (TFTs) based on transparent conducting amorphous oxide semiconductors (TAOS) such as InGaZnO (IGZO), zinc tin oxide (ZTO), zinc indium tin oxide (ZITO), etc. provide additional functionalities like transparency, high field effect mobility and potential for room temperature processing. The performance of these TAOS based TFTs are superior to their silicon (a-Si:H TFTs) and organic TFTs. Though there are monographs and books on a-Si:H TFTs and organic TFTs, a book on TAOS based TFTs is rare. This book introduces the graduate students and beginners to the field of amorphous semiconductors. The mass production of this kind of TFTs on large area substrates involves the complications associated with controlling the composition of oxide compound semiconductor thin film material. Pulsed laser deposition allows for the growth of an oxide semiconductor in a very high oxygen rich environment while co-sputtering is an effective technique for the growth of a multicomponent film and to control the film chemical composition in a systematic and easy way. These manufacturing aspects will be of interest to those working in the industry. The review on the n channel, p channel TFTs, and the detailed description on the extraction of various TFT parameters like the threshold voltage, field effect mobility, sub threshold slope and on-off ratio etc. will be ready reckoner to those working in the field of transparent electronics.

Available in PDF, EPUB and Kindle. Book excerpt: "The push to develop integrated systems using thin-film transistors (TFT) on insulating substrates (i.e. glass) has always been limited due to low-mobility semiconducting films such as amorphous and polycrystalline silicon. Corning Incorporated is developing a new substrate material known as silicon-on-glass (SiOG). It is intrinsically better than amorphous and polycrystalline silicon materials due to its single crystal nature of the silicon film. This however does not mitigate the challenges associated with low-temperature CMOS process and fabrication. The first generation of TFTs fabricated at RIT showed the potential of SiOG as a viable substrate material, but were plagued by considerable shortcomings such as high leakage and low transconductance. As part of this study, refinements to TFT processing on SiOG have demonstrated significant improvement to TFT performance and uniformity, showing increase transconductance/mobility, lower subthreshold swing, tighter VT distributions, and near symmetrical NFET and PFET operation about 0 V. With these improvements minimal steps have been added to the manufacturing process, keeping simple and adoptable by the flat panel display (FPD) industry. Device modeling clearly demonstrates the key areas important to electrical operation, such as dopant activation, interface charge/trap reduction, and workfunction engineering. In addition, modeling and simulation have helped to explain the governing physics of device operation explaining non-ideal effects such as gate induced drain leakage (GIDL) and various mobility degradation mechanisms. An overview of device design, process refinements and device operation is presented. Process modification and resulting benefits are discussed along with CMOS integration on SiOG."--Abstract.

This book was released on 2017 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solution processed metal oxide semiconductors have attracted intensive attention in the last several decades and have emerged as a promising candidate for the application of thin film transistor (TFT) due to their nature of transparency, flexibility, high mobility, simple processing technique and potential low manufacturing cost. However, metal oxide thin film fabricated by solution process usually requires a high temperature (over 300 i C), which is above the glass transition temperature of some conventional polymer substrates. In order to fabricate the flexible electronic device on polymer substrates, it is necessary to find a facile approach to lower the fabrication temperature and minimize defects in metal oxide thin film. In this thesis, the electrical properties dependency on temperature is discussed and an UV-assisted annealing method incorporating Deep ultraviolet (DUV)-decomposable additives is demonstrated, which can effectively improve electrical properties solution processed metal oxide semiconductors processed at temperature as low as 220 i C. By studying a widely used indium oxide (In2O3) TFT as a model system, it is worth noted that compared with the sample without UV treatment, the linear mobility and saturation mobility of UV-annealing sample are improved by 56% and 40% respectively. Meanwhile, the subthreshold swing is decreased by 32%, indicating UV-treated device could turn on and off more efficiently. In addition to pure In2O3 film, the similar phenomena have also been observed in indium oxide based Indium-Gallium-Zinc Oxide (IGZO) system. These finding presented in this thesis suggest that the UV assisted annealing process open a new route to fabricate high performance metal oxide semiconductors under low temperatures.

Available in PDF, EPUB and Kindle. Book excerpt: Discover the materials set to revolutionize the electronics industry The search for electronic materials that can be cheaply solution-processed into films, while simultaneously providing quality device characteristics, represents a major challenge for materials scientists. Continuous semiconducting thin films with large carrier mobilities are particularly desirable for high-speed microelectronic applications, potentially providing new opportunities for the development of low-cost, large-area, flexible computing devices, displays, sensors, and solar cells. To date, the majority of solution-processing research has focused on molecular and polymeric organic films. In contrast, this book reviews recent achievements in the search for solution-processed inorganic semiconductors and other critical electronic components. These components offer the potential for better performance and more robust thermal and mechanical stability than comparable organic-based systems. Solution Processing of Inorganic Materials covers everything from the more traditional fields of sol-gel processing and chemical bath deposition to the cutting-edge use of nanomaterials in thin-film deposition. In particular, the book focuses on materials and techniques that are compatible with high-throughput, low-cost, and low-temperature deposition processes such as spin coating, dip coating, printing, and stamping. Throughout the text, illustrations and examples of applications are provided to help the reader fully appreciate the concepts and opportunities involved in this exciting field. In addition to presenting the state-of-the-art research, the book offers extensive background material. As a result, any researcher involved or interested in electronic device fabrication can turn to this book to become fully versed in the solution-processed inorganic materials that are set to revolutionize the electronics industry.

Book excerpt: This work takes advantage of high-resolution silicon stencil masks to build air-stable complementary OTFTs using a low-temperature fabrication process. Plastic electronics based on organic thin-film transistors (OTFTs) pave the way for cheap, flexible and large-area products. Over the past few years, OTFTs have undergone remarkable advances in terms of reliability, performance and scale of integration. Many factors contribute to the allure of this technology; the masks exhibit excellent stiffness and stability, thus allowing OTFTs with submicrometer channel lengths and superb device uniformity to be patterned. Furthermore, the OTFTs employ an ultra-thin gate dielectric that provides a sufficiently high capacitance to enable the transistors to operate at voltages as low as 3 V. The critical challenges in this development are the subtle mechanisms that govern the properties of aggressively scaled OTFTs. These mechanisms, dictated by device physics, are well described and implemented into circuit-design tools to ensure adequate simulation accuracy.

This book was released on 2013-04-16 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Thin Film Transistors reviews the operation, application and technology of the main classes of thin film transistor (TFT) of current interest for large area electronics. The TFT materials covered include hydrogenated amorphous silicon (a-Si:H), poly-crystalline silicon (poly-Si), transparent amorphous oxide semiconductors (AOS), and organic semiconductors. The large scale manufacturing of a-Si:H TFTs forms the basis of the active matrix flat panel display industry. Poly-Si TFTs facilitate the integration of electronic circuits into portable active matrix liquid crystal displays, and are increasingly used in active matrix organic light emitting diode (AMOLED) displays for smart phones. The recently developed AOS TFTs are seen as an alternative option to poly-Si and a-Si:H for AMOLED TV and large AMLCD TV applications, respectively. The organic TFTs are regarded as a cost effective route into flexible electronics. As well as treating the highly divergent preparation and properties of these materials, the physics of the devices fabricated from them is also covered, with emphasis on performance features such as carrier mobility limitations, leakage currents and instability mechanisms. The thin film transistors implemented with these materials are the conventional, insulated gate field effect transistors, and a further chapter describes a new thin film transistor structure: the source gated transistor, SGT. The driving force behind much of the development of TFTs has been their application to AMLCDs, and there is a chapter dealing with the operation of these displays, as well as of AMOLED and electrophoretic displays. A discussion of TFT and pixel layout issues is also included. For students and new-comers to the field, introductory chapters deal with basic semiconductor surface physics, and with classical MOSFET operation. These topics are handled analytically, so that the underlying device physics is clearly revealed. These treatments are then used as a reference point, from which the impact of additional band-gap states on TFT behaviour can be readily appreciated. This reference book, covering all the major TFT technologies, will be of interest to a wide range of scientists and engineers in the large area electronics industry. It will also be a broad introduction for research students and other scientists entering the field, as well as providing an accessible and comprehensive overview for undergraduate and postgraduate teaching programmes.

Available in PDF, EPUB and Kindle. Book excerpt: A process for formation of thin film transistors (TFTs) on plastic substrates replaces standard thin film transistor fabrication techniques, and uses sufficiently lower processing temperatures so that inexpensive plastic substrates may be used in place of standard glass, quartz, and silicon wafer-based substrates. The process relies on techniques for depositing semiconductors, dielectrics, and metals at low temperatures; crystallizing and doping semiconductor layers in the TFT with a pulsed energy source; and creating top-gate self-aligned as well as back-gate TFT structures. The process enables the fabrication of amorphous and polycrystalline channel silicon TFTs at temperatures sufficiently low to prevent damage to plastic substrates. The process has use in large area low cost electronics, such as flat panel displays and portable electronics.
