  • Patent number: 9728403
    Abstract: The present invention provides an array substrate and a manufacturing method thereof. The manufacturing method of the array substrate according to the present invention forms a gate electrode in the same metal layer with source and drain electrodes and divides a common electrode layer that is conventionally in the form of an entire surface into two portions, of which one serves as a common electrode, while the other portion feeds an input of a gate scan signal thereby eliminating an operation of forming an interlayer insulation layer and thus reducing manufacturing cost of the operation. The array substrate of the present invention comprises a gate electrode that is formed in the same metal layer with source and drain electrodes so that no interlayer insulation layer is present between the gate electrode and the source and drain electrodes, thereby simplifying the structure and reducing the manufacturing cost of the array substrate.

  • Patent number: 7678627
    Abstract: In a process for producing a TFT display, a polysilicon layer is patterned to define a first and a second TFT regions. A first doping material is implanted into a first exposed portion in the first TFT region to define a first doped region and a first channel region, and implanted into a second exposed portion in the second TFT region to define a second doped region and a second channel region. A second doping material is implanted into a third exposed portion smaller than the first exposed portion to form first source/drain regions and simultaneously define a first LDD region in the first TFT region. A first and a second gate structures are formed over the first and the second channel regions, respectively. In a certain direction, the first gate structure is longer than the first channel, and the second gate structure isn't longer than the second channel region.
