Abstract:
1. A method for manufacturing a thin-film transistor (TFT) for a display device, comprising: providing a substrate; forming a gate line over the substrate, wherein the gate line defines a gate for the TFT; forming at least one hole in the gate line, wherein forming the at least one hole comprises forming a first hole in a region of the gate line generally below where a drain of the TFT will be formed; forming a metal oxide active layer over the gate line; forming an etch stopper layer over the metal oxide active layer; forming a first hole and a second hole in the etch stopper layer; depositing conductive material over the first and second holes to form a source over first hole and a drain over the second hole; forming an organic passivation layer over the source and drain; etching a third hole in the organic passivation layer that exposes at least a portion of the drain; forming a common voltage electrode over the organic passivation layer and the exposed portion of the drain; etching a fourth hole in the common voltage electrode layer that exposes at least a portion of the organic passivation layer and the drain; forming a passivation layer over the common voltage electrode layer and the exposed portions of the organic passivation layer and the drain; and etching a fifth hole that exposes a portion of the drain; wherein the first hole is at least partially overlapped by the drain.
