摘要： A thin-film transistor (TFT) is described to have a gate layer, an insulating layer, a semiconductor layer, and a source/drain layer formed on a flexible substrate. The source and the drain layers are separated by a channel with a special shape. This does not only increase the aspect ratio of the channel per unit area, the source and the drain also have multiple directions for transmitting carriers. The carrier mobility of the TFT is thus enhanced with uniform and stable circuit properties.
