  • Publication number: 20090184319
    Abstract: A method of manufacturing a display substrate is described. In the method, a gate line and a gate electrode are formed on a base substrate. A source metal layer is formed on the base substrate having the gate line and the gate electrode. A data line, a source electrode and a drain electrode are formed by etching the source metal layer by using an etching gas. An additive gas is provided to the base substrate having the drain electrode so that the additive gas reacts with an etching component of the etching gas to remove a by-product formed at an exposed portion of the data line, the source electrode and drain electrode. Thus, corrosion of the fine pattern due to an etching gas may be prevented and/or reduced.
