Abstract
A method for fabricating a pixel structure includes the following steps. A patterned semiconductor layer, an insulation layer, and a patterned metal layer are formed on a substrate sequentially. A first inter-layer dielectric (ILD) layer is formed to cover the patterned metal layer. A low temperature annealing process is performed after forming the first ILD layer. A hydrogen plasma treatment process is performed after the low temperature annealing process. A second ILD layer is formed to cover the first ILD layer after the hydrogen plasma treatment process. A third ILD layer is formed to cover the second ILD layer. A source electrode and a drain electrode are formed on the third ILD layer. A passivation layer is formed on the source electrode and the drain electrode. A pixel electrode is formed on the passivation layer. A pixel structure manufactured by the above-mentioned method is also provided.
