This article is about TFT technology. For thin-film-transistor liquid-crystal display, see TFT LCD.
A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is made by thin film deposition. TFTs are grown on a supporting (but non-conducting) substrate, such as glass. This differs from the conventional bulk metal oxide field effect transistor (MOSFET), where the semiconductor material typically is the substrate, such as a silicon wafer.[1] The traditional application of TFTs is in TFT liquid-crystal displays.
