Patent ID: 7609331

Claim:
A method of manufacturing an array substrate for a liquid crystal display device, comprising: depositing a first metal layer on a transparent substrate; patterning the first metal layer to form a gate line; a gate electrode; and a gate pad; forming a gate insulating layer over the transparent substrate and the patterned first metal layer; depositing a doped amorphous silicon layer and a second metal layer over the gate insulating layer; providing a photoresist pattern having first and second thicknesses over the second metal layer; selectively removing portions of the second metal layer according to the photoresist pattern; selectively removing portions of the amorphous silicon layer according to the photoresist pattern and selectively etching the gate insulating layer according to the photoresist pattern; removing a portion of the photoresist pattern having the first thickness; selectively etching the second metal layer exposed by removing the portion of the photoresist pattern having the first thickness; selectively etching the doped amorphous silicon layer exposed by selectively etching the second metal layer exposed by removing the photoresist pattern having the first thickness; removing the remaining photoresist pattern; depositing and patterning a transparent conductive material; forming a first passivation layer over an entire surface of the transparent substrate including the transparent conductive layer; forming a second passivation layer over selective portions of the first passivation layer by a printing method; and dry-etching the first passivation layer using the second passivation layer as an etching mask.
