A thin-film transistor (TFT) is a type of field-effect transistor that is usually used in a liquid crystal display (LCD). This type of display features a TFT for each individual pixel. These TFTs act as individual switches that allow the pixels to change state rapidly, making them turn ...
and to implement high definition, by providing a minute crystal silicon film, a polycrystalline silicon film or amorphous silicon film, whose impurity concentration is lower than that of a source electrode or a drain electrode, between a polycrystalline silicon film and at least the drain electrode...
Thin film transistor The object described above can be achieved by realizing a high mobility thin film transistor device in a manner forming a channel with crystal grains having large grain size and controlled crystal orientations by paying attention to a fa... S Yamaguchi,M Hatano,T Shiba,.....
TFT-LCD devices include a plurality of pixels and each pixel includes a thin-film transistor (TFT) and an opaque LDD electrode which is capacitively coupled to a portion of the TFT's active layer, so that an impurity doped LDD region is not necessary and improved device characteristics can ...
13.2.1Thin-film transistors The TFT-LCD andOLEDdisplays that are currently popular in the market are similar in structure, both using thethin-film transistor(TFT) array as the driving circuit to control each pixel (one of the smallest units in the image), and each pixel is divided into thr...
FIGURE 27.2.(a) Cross-section of a field-effect transistor at the 45-nm technology node. The transistor contains a hafnium-based high-kdielectric, with a thickness of ∼3nm, as the gate oxide (intel.com). (b) Illustration of film growth in which the thickness is controlled at the subn...

A thin-film transistor includes a gate layer, a gate insulting layer, a semiconductor layer, a drain layer, a passivation layer (each of which being formed on or over an insulating substrate), and a conductive layer formed on the passivation layer. The conductive layer is connected to the ...
gate insulating film for an inverted stagger thin-film transistor, at a thin-film transistor which is used to switch a liquid crystal at an active matrix liquid crystal display, is constituted by two layers and the film whose dielectric breakdown strength is high is formed as a first layer. ...
