    摘要: A thin film etching method is provided, which is used for manufacturing semiconductor device or thin film transistor (TFT) array and through which no undercut may be presented or a good after-etching shape may be achieved with respect to a thin film thus etched. The thin film etching method is performed in a two-stage manner by an etchant and between the two stages a photoresist removing process is inserted where another etchant is used. With execution of the photoresist removing process, the thin film may have an increased contact area with the etchant. As such, any undercut or undesired after-etching shape existed in the thin film etched by the prior art may be eliminated or improved.

    摘要: 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.
