Patent ID: 7238556

Claim:
A method of forming a thin film transistor (TFT) structure, said method comprising the steps of: providing a substrate having a first surface and a second surface; forming a plurality of stacked structures on said first surface of said substrate, each stacked structure including a first conducting layer, an insulation layer, an amorphous silicon layer, and an ohmic contact layer; forming a patterned photo-imagable layer between said plurality of stacked structures so as to be in contact with the first conducting layer, the insulation layer, the amorphous silicon layer and the ohmic contact layer; forming a second conducting layer on said patterned photo-imagable layer and said ohmic contact layer; patterning said second conducting layer and said ohmic contact layer to expose said amorphous silicon layer, wherein a source electrode and a drain electrode are formed on the photo-imagable layer; forming a passivation layer on said amorphous layer and said second conducting layer; and forming a transparent electrode on said passivation layer and electrically connecting to said second conducting layer.
