Patent ID: 6869833

Claim:
A method for fabricating a thin film transistor (TM of a liquid crystal display (LCD), the method comprising the steps of: providing a substrate; sequentially depositing a transparent conductive layer, a first metal layer, a first insulating layer, a semiconductor layer, and a second metal layer on the substrate; performing a first photo-etching-process (PEP) to remove portions of the second metal layer, the semiconductor layer, the first insulating layer, the first metal layer, and the transparent conductive layer to form a source electrode, a drain electrode and a channel region; depositing a second insulating layer and performing a second PEP to remove portions of the second insulating layer to form a plurality of contact holes; and depositing a third metal layer for electrically connecting the source electrode and the drain electrode with other wires, depositing a passivation layer for protecting the third metal layer, and performing a third PEP to remove portions of the third metal layer and the passivation layer.
