Abstract:
A method for manufacturing a thin film transistor-liquid crystal display, comprising the steps of:depositing a gate metal on a substrate; forming a gate electrode by etching said gate metal; depositing an insulating layer on said gate electrode; depositing an amorphous silicon layer on said insulating layer; depositing an n+ amorphous silicon layer on said amorphous silicon layer; depositing a source/drain metal layer on said n+ amorphous silicon layer; simultaneously etching the three layers of said source/drain metal layer, n+ amorphous silicon layer and said amorphous silicon layer until said insulating layer is exposed to form a triple layer pattern; etching said source/drain electrode metal layer and n+amorphous silicon layer to form a separated source/drain electrode pattern and expose a portion of said amorphous silicon layer between the source and drain electrodes; and depositing a passivation layer covering said exposed portion of said amorphous silicon layer and said exposed portion of said insulating layer.
