  • Patent number: 10109809
    Abstract: A flexible substrate includes a polymer substrate and a plurality of water and oxygen barrier layers provided on the polymer substrate. A planarization layer is provided between the adjacent water and oxygen barrier layers. The planarization layer includes a plurality of planarization units separated in a first direction and a second direction.

  • Patent number: 6670641
    Abstract: A thin film transistor (TFT) is provided with a precisely, lightly doped drain (LDD) structure formed on a substrate of insulators, such as a glass sheet. A method of making the TFT and a liquid crystal display device with the same are disclosed. The TFT with the LDD structure include a side wall and a gate insulation layer. An intermediate layer is provided between the side wall and the gate insulation layer. The intermediate layer is different in layer property from the side wall. When the side wall is formed by an anisotropic etching process, the etching can be stopped on the surface of intermediate layer. As a result, the gate insulation layer and the substrate are protected against the etching.

  • Patent number: 6037195
    Abstract: A process of producing a thin film transistor of a liquid crystal display device according to the present invention comprises the steps of forming a semiconductor layer on an insulation substrate, stacking an insulation film and a conductive layer on the semiconductor layer, patterning the conductive layer to form a gate electrode, reducing a width of a mask used at formation of the gate electrode in a prescribed amount to form an offset region, implanting highly concentrated impurity ions into a part of the semiconductor layer where there are not the mask or the conductive layer to form an N.sup.+ -polysilicon layer, re-etching the conductive layer by using the mask used at formation of the gate electrode made narrower by the offset region, and implanting low concentrated impurity ions into the semiconductor layer below the conductor region removed by re-etching to form an N.sup.- -polysilicon layer.
