Patent ID: 7816193

Claim:
A method for fabricating a pixel structure for LCDs, comprising: providing a substrate with a predetermined driving element region and a display region; forming a patterned first conductive layer on the substrate to form a gate electrode on the predetermined driving element region of the substrate; sequentially forming a gate dielectric layer, a semiconductor layer, and a second conductive layer on the substrate, and patterning the second conductive layer, the semiconductor layer and the gate dielectric layer to form patterned gate dielectric layer, semiconductor layer, and second conductive layer covering the gate electrode; conformally forming a transparent conductive layer on the patterned second conductive layer and the substrate and patterning the transparent conductive layer to form a patterned transparent conductive layer covering part of the patterned second conductive layer and the display region of the substrate; etching the patterned second conductive layer over the gate electrode with the patterned transparent conductive layer serving as a mask to form a source electrode and a drain electrode, wherein the source electrode, drain electrode, patterned gate dielectric layer, patterned semiconductor layer, and the gate electrode construct a thin film transistor (TFT); conformally forming a passivation layer on the TFT and the substrate; and patterning the passivation layer to form a patterned passivation layer on the TFT by back exposure with the patterned first and second conductive layer as mask.
