Patent ID: 8658480

Claim:
A method for manufacturing an active array substrate, the method comprising: sequentially forming a transparent conductive layer and a first metal layer to cover a substrate; forming a first patterned photoresist layer having a halftone portion on the first metal layer and exposing an exposed portion of the first metal layer; removing the exposed portion of the first metal layer and a portion of the transparent conductive layer therebeneath to form a first patterned metal layer and a patterned transparent conductive layer, respectively, and removing the halftone portion of the first patterned photoresist layer to expose an exposed portion of the first patterned metal layer; removing the exposed portion of the first patterned metal layer, and removing a remaining portion of the first patterned photoresist layer to form an intermediate structure; sequentially forming a semiconductor layer, an insulating layer and a second metal layer to cover the intermediate structure; forming a second patterned photoresist layer on the second metal layer, wherein an exposed portion of the second metal layer is exposed; removing the exposed portion of the second metal layer, and a portion of the insulating layer and a portion of the semiconductor layer underlying the exposed portion of the second metal layer to form a stacked structure composed of a second patterned metal layer, a patterned insulating layer and a patterned semiconductor layer; and heating the second patterned photoresist layer to become flowable, thereby forming a passivation layer covering the stacked structure.
