According to a method of manufacturing a thin-film transistor (TFT) substrate, a gate insulation layer, a semiconductor layer, an ohmic contact layer, and a data metal layer are sequentially formed on a substrate. A photoresist pattern is formed in a source electrode area and a drain electrode area. A data metal layer is etched using the photoresist pattern as an etch-stop layer to form a data wire including a source electrode and a drain electrode. A photoresist pattern is reflowed to cover a channel region between a source electrode and the drain electrode. An ohmic contact layer and the semiconductor layer are etched using the reflowed photoresist pattern as an etch-stop layer to form an active pattern including an ohmic contact pattern and a semiconductor pattern. The reflowed photoresist pattern is etched back to expose a portion of the ohmic contact pattern in the channel region. The ohmic contact pattern is etched using the etched-back photoresist pattern as an etch-stop layer. |
