  • Patent number: 9147700
    Abstract: A manufacturing method of an array substrate includes following steps. A first photolithography process is performed to form a gate electrode on a substrate. A gate insulating layer is formed to cover the substrate and the gate electrode. A second photolithography process is performed to form a patterned semiconductor layer and a patterned etching stop layer. A semiconductor layer and an etching stop layer are successively formed on the gate insulating layer, and a second patterned photoresist is formed on the etching stop layer. The etching stop layer uncovered by the second patterned photoresist is removed. The semiconductor layer uncovered by the second patterned photoresist is removed for forming the patterned semiconductor on the gate insulating layer.

  • Patent number: 8969146
    Abstract: A manufacturing method of an array substrate includes the following steps. A gate electrode and a gate insulator layer are successively formed on a substrate. A semiconductor layer, an etching stop layer, a hard mask layer, and a second patterned photoresist are successively formed on the gate insulator layer. The second patterned photoresist is employed for performing an over etching process to the hard mask layer to form a patterned hard mask layer. The second patterned photoresist is employed for performing a first etching process to the etching stop layer. The second patterned photoresist is then employed for performing a second etching process to the semiconductor layer to form a patterned semiconductor layer. The etching stop layer uncovered by the patterned hard mask layer is then removed for forming a patterned etching stop layer.

  • Patent number: 8759165
    Abstract: A manufacturing method of an array substrate includes the following steps. A first conductive layer, a gate insulating layer, a semiconductor layer, an etching stop layer, and a first patterned photoresist are successively formed on a substrate. The etching stop layer and the semiconductor layer uncovered by the first patterned photoresist are then removed by a first etching process. A patterned gate insulating layer and a patterned etching stop layer are then formed through a second etching process. The first conductive layer uncovered by the patterned gate insulating layer is then removed to form a gate electrode. The semiconductor layer uncovered by the patterned etching stop layer is then removed to form a patterned semiconductor layer and partially expose the patterned gate insulating layer.

  • Patent number: 7842953
    Abstract: A pixel structure disposed on a substrate and including a common line, a reserved line, a dielectric layer, two repair lines, an active device, and a pixel electrode is provided. The reserved line and the common line are disposed on the substrate and are covered by the dielectric layer. The repair lines are disposed on the dielectric layer, and each repair line has a first repairing region overlapped with the common line and a second repairing region overlapped with the reserved line. When the common line is open, the repair lines in the first and second repairing regions are connected with the common line and the reserved line, such that the common line, the repair lines, and the reserved line are electrically connected. After the common line, the repair lines, and the reserved line are connected, the above-mentioned pixel structure is effectively repaired.
