Thin-Film Transistor (TFT)

11.04.08

A thin-film transistor (TFT) is a special kind of field-effect transistor made by depositing thin films of a semiconductor active layer as well as the dielectric layer and metallic contacts over a supporting substrate. A common substrate is glass, since the primary application of TFTs is in liquid crystal displays. This differs from the conventional transistor where the semiconductor material typically is the substrate, such as a silicon wafer.

  • Offset Liquid Embossing (OLE)

    A method for additively printing nanoparticles and spin-on-glasses. OLE utilizes the transfer of patterned material from a polydimethylsiloxane surface of tuned wettability to a rigid or flexible substrate. Multiple layers can be aligned and printed…

  • Amorphous

    An amorphous solid is a solid in which there is no long-range order of the positions of the atoms. Most classes of solid materials can be found or prepared in an amorphous form. For instance, common window glass is an amorphous ceramic, many polymers…

  • Indium tin oxide

    Indium tin oxide is a solid solution of indium oxide and tin oxide, typically 90% In2O3, 10% SnO2 by weight. It is transparent and colorless in thin layers. In bulk form, it is yellowish to grey. In the infrared region of the spectrum it is a metal-l…
