  • Publication number: 20160035893
    Abstract: A manufacturing method of a pixel structure is provided, which includes following steps. A gate and a gate insulating layer are formed on a substrate. A source and a drain are formed on the gate insulating layer. A first and a second semiconductor pattern are formed on the gate insulating layer. The first semiconductor pattern is located above the gate, wherein the first semiconductor pattern contacts the source and the drain. The second semiconductor pattern contacts the drain. A mask which exposes both sides of the first semiconductor pattern is formed on the first semiconductor pattern. A treatment procedure is performed, so that a first and a second conductive region are formed at both sides of the exposed first semiconductor pattern, and the second semiconductor pattern is formed into a pixel electrode pattern. The first semiconductor pattern which is covered by the mask is formed into a channel region.

  • Patent number: 7432564
    Abstract: A method for fabricating a pixel structure is provided. First, a gate, a scan line, and a first terminal are formed on a substrate. A gate insulating layer is formed over the substrate to cover the gate, the scan line, and the first terminal. After defining the semiconductor layer, the gate insulating layer is patterned to exposure the first terminal. A transparent conductive layer is formed over the substrate and a patterned photoresist layer is formed on the transparent conductive layer. The transparent conductive layer is patterned using the patterned photoresist layer as a mask, so as to define a source, a drain, a data line, a pixel electrode, a second terminal, and a contact pad. Because only four photomasks are used to implement the above method for fabricating the pixel structure, the cost of manufacturing can be reduced.
