摘要:
A method of manufacturing a semiconductor device, the method includes: providing a gate electrode on a substrate; providing a first interlayer insulating layer to cover the gate electrode on the substrate; providing an oxide semiconductor layer corresponding to the gate electrode on the first interlayer insulating layer; providing a source electrode and a drain electrode, which are in contact with the oxide semiconductor layer, on the first interlayer insulating layer; and heat-treating the oxide semiconductor layer using Joule heat generated therein from a flow of a drain current by applying a voltage to the source electrode or the drain electrode.
