Process Optimization of Deposition Conditions for Low Temperature Thin Film Insulators used in Thin Film Transistors Displays
Deposition process for thin insulator used in polysilicon gate dielectric of thin film transistors are optimized. Silane and N2O plasma are used to form SiO2 layers at temperatures below 150 ºC. The deposition conditions as well as system operating parameters such as pressure, temperature, gas flow ratios, total flow rate and plasma power are also studied and their effects are discussed. The p...
متن کاملAzine- and Azole-Functionalized Oligo´ and Polythiophene Semiconductors for Organic Thin-Film Transistors
In the organic electronics research field, several strategies have been used to modulate the transport properties of thiophene-derived semiconductors via sequential functionalization of their π-conjugated cores. This review summarizes the major design and synthetic strategies for tuning thiophene-containing small molecule and polymer properties by introducing electron-deficient nitrogen-contain...

متن کاملChemical and biological sensors using polycrystalline silicon TFTs
Over the past three decades effort has been devoted to exploit the field-effect mechanism in chemical and biological sensors, due to the potential of these devices to provide large arrays of sensors that are label-free, low-cost, disposable and can be easily integrated in portable instrumentation. Most of this work concerned the development of ion-sensitive field-effect transistors. More recent...
متن کاملLiquid-crystalline processing of highly oriented carbon nanotube arrays for thin-film transistors.
We introduce a simple solution-based method for the fabrication of highly oriented carbon nanotube (CNT) arrays to be used for thin-film transistors. We exploit the liquid-crystalline behavior of a CNT solution near the receding contact line during tilted-drop casting and produced long-range nematic-like ordering of carbon nanotube stripes caused by confined micropatterned geometry. We further ...
