Zunqing SONG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10770595
    Abstract: A thin film transistor, a method for manufacturing the same and a display device are provided in the present disclosure. The thin film transistor includes an active layer, a first electrode and a second electrode, and a gate electrode. The active layer includes an active layer body and an electrode hole in a center of the active layer body. The gate electrode is insulated and spaced apart from the active layer body and is disposed to surround the electrode hole. The first electrode and the second electrode are insulated from each other, both coupled to the active layer body, and insulated and spaced apart from the gate electrode. At least a portion of an orthographic projection of the first electrode on the active layer is within the electrode hole. An orthographic projection of the second electrode on the active layer surrounds the active layer body.
    Type: Grant

  • Patent number: 10297678
    Abstract: The present disclosure provides a method for manufacturing a thin film transistor comprising, forming a pattern of an active layer on a substrate through a patterning process; performing ion doping to a channel region of the active layer; forming a gate insulating layer; forming a pattern of a gate through the patterning process; performing ion doping to a source contact region and a drain contact region of the active layer; forming an interlayer insulating layer; and performing laser annealing to the active layer, so as to make the active layer crystallize and the ions doped in the channel region, the source contact region and the drain contact region of the active layer activate simultaneously. In this method, the crystallization of the active layer and the activation of the ions doped in the active layer are implemented in the same process, which reduces the process cost and improves the efficiency.
