Patent ID: 8017465

Claim:
A method for manufacturing an array substrate of liquid crystal display, comprising: a. providing a substrate having a gate line, a gate insulating layer and an active layer pattern formed thereon in this order; b. depositing a first transparent conductive layer and a source/drain metal layer in this order on the substrate; c. forming a photoresist pattern layer on the source/drain metal layer through a triple-tone mask; d. performing a wet-etching process on the source/drain metal layer and the first transparent conductive layer exposed from the photoresist pattern layer; e. performing a first ashing process on the photoresist pattern layer and performing a dry-etching process on the source/drain metal layer, the first transparent conductive layer and the active layer pattern exposed by the first ashing process; f. performing a second ashing process on the photoresist pattern layer and performing a wet-etching process on the source/drain metal layer exposed by the second ashing process; and g. removing the remaining photoresist pattern layer.
