Classification: CPC H | IPC H

Claim 9:
10. A method of manufacturing an array substrate, comprising following steps:
S10: providing a substrate, sequentially manufacturing an active layer and a metal contact layer on the substrate, performing a lithography process on the active layer and the metal contact layer with a photomask, and oxidizing a portion of the metal contact layer to form a conductive area and an insulating area, thereby defining a channel area of the active layer;
S20: manufacturing a gate insulating layer on the metal contact layer, manufacturing a gate layer on the gate insulating layer, and performing a lithography process on the gate layer and the gate insulating layer to form a gate; and
S30: manufacturing an interlayer insulating layer on the gate layer, manufacturing a source/drain layer on the interlayer insulating layer, and performing a lithography process on the source/drain layer to form a source and a drain which are individually connected to the conductive area.
