Abstract:
1. A method of manufacturing an oxide semiconductor thin film transistor, comprising: forming a gate metal layer on a substrate; forming a gate insulating layer on the gate metal layer; forming a first transition layer on the gate insulating layer; forming an oxide semiconductor layer on the first transition layer, the oxygen content of the first transition layer is higher than the oxygen content of the oxide semiconductor layer; forming a blocking layer on the oxide semiconductor layer; forming a source/drain metal layer on the blocking layer, the oxide semiconductor layer and the gate insulating layer; and forming a passivation layer on the source/drain metal layer, the gate insulating layer and a part of the blocking layer; the method further comprising: forming a second transition layer between the blocking layer and the oxide semiconductor layer, the oxygen content of the second transition layer is higher than the oxygen content of the oxide semiconductor layer.
