Patent ID: 7015508

Claim:
A thin film transistor (TFT) structure, comprising: a plurality of stacked structures on a substrate, said plurality of stacked structures including a first conducting layer, an insulation layer, an amorphous silicon layer and an ohmic contact layer; a photo-imagable layer between said plurality of stacked structures so as to be contact with the first conducting layer, the insulation layer, the amorphous silicon layer and the ohmic contact layer; a source electrode and a drain electrode on said photo-imagable layer, wherein said source electrode is connected to a portion of said amorphous silicon layer and said drain electrode is connected to another portion of said amorphous silicon layer; a passivation layer on said amorphous silicon layer, said source electrode and said drain electrode; and a transparent electrode on said passivation layer and electrically connected to one of said source electrode and said drain electrode.
