Patents by Inventor Dongkoog Jang

Dongkoog Jang 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: 10014326
    Abstract: A method for fabricating an array substrate, an array substrate and a display device are provided. The method for fabricating the array substrate includes: forming a spacer layer on the array substrate, the spacer layer is disposed under a planarized layer and corresponds to a location of a via hole in the planarized layer, wherein the planarized layer is formed of a hot melt material.
    Type: Grant
    Filed: March 25, 2013
    Date of Patent: July 3, 2018
    Assignees: BOE TECHNOLOGY GROUP CO., LTD., CHENGDU BOE OPTOELECTRONICS TECHNOLOGY CO., LTD.
    Inventors: Xiaodan Wei, Xingqiang Zhang, Zhong Lu, Dongkoog Jang
  • Patent number: 9337312
    Abstract: The method for manufacturing the TFT includes: forming a semiconductor film, a doped semiconductor film, a source/drain electrode film, and a first patterned photoresist layer sequentially; performing first etching to remove the source/drain electrode film on a region that is not covered by the first patterned photoresist layer; performing second etching to remove the doped semiconductor film and the semiconductor film on a region that is not covered by the first patterned photoresist layer; performing ashing treatment on the photoresist layer to remove the photoresist layer on the channel region; hard-baking the photoresist layer after the ashing treatment; performing third etching to remove the source/drain electrode film on a region that is not covered by the photoresist layer; and performing fourth etching to remove the doped semiconductor film on the region that is not covered by the photoresist layer.
