Abstract:
A method for manufacturing a thin film transistor, a method for manufacturing an array substrate, an array substrate, and a display device are provided. The method for manufacturing the thin film transistor includes: forming an active layer on a base substrate; forming a metal layer on the surface of the active layer; and processing the metal layer using a patterning process for one time and an oxidation treatment process, so that the metal layer forms a source electrode, a drain electrode and a passivation layer; wherein the source electrode and the drain electrode are in contact with the active layer, and the passivation layer is formed on a side of the source electrode and the drain electrode away from the active layer.

Claim (Index 14):
The method for manufacturing the array substrate according to  claim 13 , wherein, the processing the metal layer using the patterning process for one time and the oxidation treatment process so that the metal layer forms the source electrode and the drain electrode, the passivation layer and the conductive portion connected to the source electrode and the drain electrode comprises:\n forming a photoresist layer on a surface of the metal layer; processing the photoresist layer using the patterning process for one time to form a photoresist completely-removed region, photoresist partly-reserved regions and a photoresist completely-reserved region; the photoresist partly-reserved regions are connected to the photoresist completely-reserved region; performing a complete oxidation treatment on a region of the metal layer corresponding to the photoresist completely-removed region to form a first passivation portion; removing a photoresist in the photoresist partly-reserved regions; performing a partially oxidation treatment on a region of the metal layer corresponding to the photoresist partly-reserved regions to form the source electrode, the drain electrode and a second passivation portion; wherein the source electrode and the drain electrode are in contact with the active layer, and the second passivation portion are formed on a side of the source electrode and the drain electrode away from the active layer; the first passivation portion and the second passivation portion form the passivation layer; removing a photoresist in the photoresist completely-reserved region to form the conductive portion connected with the source electrode and the drain electrode.
