Patent ID: 7897442

Claim:
A method for fabricating a pixel structure, comprising: providing a substrate; forming a first conductive layer over the substrate; providing a first shadow mask over the first conductive layer, wherein the first shadow mask exposes a portion of the first conductive layer; applying a laser ablation process through the first shadow mask to irradiate the first conductive layer to remove the exposed portion of the first conductive layer and form a gate; forming a gate dielectric layer over the substrate to cover the gate; forming a channel layer on the gate dielectric layer above the gate; forming a source and a drain on the channel layer above both sides of the gate, wherein the gate, the channel layer, the source and the drain together constitute a thin film transistor; forming a patterned passivation layer over the thin film transistor to cover the channel layer and expose the drain; and forming an electrode material layer to cover the patterned passivation layer and the exposed drain, wherein the patterned passivation layer is used to pattern the electrode material layer to form a pixel electrode.
