Patent ID: 7049163

Claim:
A manufacture method of pixel structure, comprising: forming a gate electrode over a substrate; forming a gate insulating layer over the substrate, and covering the gate electrode; forming a semiconductor layer over the gate insulating layer; forming a metal layer over the semiconductor layer; forming a first mask layer over the metal layer; patterning the metal layer to form source/drain electrodes, using the first mask layer as an etching mask, wherein a portion of the semiconductor in thickness is also removed; forming a second mask layer over the first mask layer, and the second mask layer further covering a region between the source/drain electrodes; patterning the semiconductor layer, using the first mask layer and the second mask layer as an etching mask; removing the first mask layer and the second mask layer; forming a passivation layer over the substrate; and forming a pixel electrode over the passivation layer, wherein the pixel electrode is electrically coupled with a drain electrode of the source/drain electrodes.
