  • Patent number: 10658516
    Abstract: Disclosed is a thin film transistor, an array substrate, a method for manufacturing the same, and a display device. The method includes: forming a source and drain on a base substrate and forming a semiconductor layer. Between the step of forming the source and drain and the step of forming the semiconductor layer, the method further includes: forming a diffusion barrier layer. Metal atoms diffused from the source and drain and passing through the diffusion barrier layer react with a part of the semiconductor layer near the source and drain, and a metal transition layer containing metal silicide is formed.

  • Patent number: 9647141
    Abstract: Embodiments of the present disclosure provide a thin film transistor (TFT) and a method of manufacturing the same, which enables to decrease the vertical resistance from the source and the drain to the polarity inversion region, so that the current from the source and the drain to the polarity inversion region may be increased, thereby improving the performances of the TFT. An active layer of the TFT is provided with a first groove and a second groove which neither pass through the active layer. A source and a drain of the TFT are formed at least partially in the first groove and the second groove, respectively. The source and the drain contact the active layer through the first groove and the second groove, respectively.
