摘要: A substrate comprising a thin-film-transistor (TFT) region, a pixel region, a gate-line region and a data-line region is provided. A transparent conductive layer and a first metal layer are orderly formed on the substrate. A conductive stack layer is formed within each of the TFT/pixel/gate-line regions and the end of the data-line region. Next, a first insulating layer and a semiconductor layer are orderly formed, and a patterned first insulating layer and a patterned semiconductor layer are formed above the conductive stack layer within the TFT region. Then, a second metal layer and a first photoresist layer are respectively formed. Afterwards, the second and the first metal layers are patterned by using the first photoresist layer as a photomask. Finally, the first photoresist layer is reflowed by heat, and part of the reflowed first photoresist layer covers a channel formed within the TFT region.

摘要: A method for fabricating a pixel structure using a laser ablation process is provided. This fabrication method forms a gate, a channel layer, a source, a drain, a passivation layer, and a pixel electrode sequentially by using a laser ablation process. Particularly, the fabrication method is not similar to a photolithography and etching process, so as to reduce the complicated photolithography and etching processes, such as spin coating process, soft-bake, hard-bake, exposure, developing, etching, and stripping. Therefore, the fabrication method simplifies the process and thus reduces the fabrication cost.

摘要: A method for fabricating a TFT array substrate includes following steps. A gate pattern and a first pad pattern are formed on a substrate. A gate insulation layer and a semiconductor layer covering the two patterns are sequentially formed. A patterned photoresist layer having different resist blocks is formed, and patterns and thicknesses of the resist blocks in different regions are adjusted. The semiconductor layer and the gate insulation layer above the first pad pattern are removed through performing an etching process and reducing a thickness of the patterned photoresist layer. After removing the patterned photoresist layer, a source pattern, a drain pattern, and a second pad pattern electrically connected to the first pad pattern are formed. A patterned passivation layer is formed on the gate insulation layer and has a second opening exposing the source pattern or the drain pattern and a third opening exposing the second pad pattern.
