Abstract:
1. A method for manufacturing a pixel structure, comprising: forming a first conductive layer on a substrate; patterning the first conductive layer using a first mask as an etching mask to form a gate; forming a dielectric layer over the substrate to cover the gate; sequentially forming a semiconductor material layer and a second conductive layer over the dielectric layer; patterning the second conductive layer using a second mask as an etching mask to form a pixel electrode; forming a patterned photo-resist layer over the substrate using the first mask as an etching mask, such that the semiconductor material layer above the gate is protected; patterning the semiconductor material layer to form a semiconductor layer using the pixel electrode and the patterned photo-resist layer as an etching mask; removing the patterned photo-resist layer; forming a third conductive layer over the substrate; and patterning the third conductive layer to form a source/drain by using a third mask, wherein the drain is electrically connected to the pixel electrode.
