Abstract
A thin-film transistor (TFT) may include a channel layer, an etch stop multi-layer, a source, a drain, a gate, and a gate insulation layer. The etch stop multi-layer may include a first etch stop layer and a second etch stop layer. The second etch stop layer may prevent or reduce an etchant from contacting the channel layer.
