Abstract:
1. A method of fabricating a flat panel display device with oxide thin film transistors, the method comprising: forming a gate electrode and a gate line, and the gate line and a data line which will be formed through the following process crossing each other and defining a pixel region on a substrate; forming a gate insulation layer on the substrate provided with the gate electrode and the gate line; forming a pixel electrode in the pixel region on the gate insulation layer; forming an oxide channel layer over the gate electrode, wherein the gate insulation layer is between the oxide channel layer and the gate electrode; forming an insulating etch stopper on the oxide channel layer and step coverage compensation patterns at a step portion formed by the gate line and the gate electrode, the step coverage compensation patterns formed in a same layer as the insulating etch stopper; forming the data line, and the source and drain electrodes which are contacted with the oxide channel layer on the substrate with the insulating etch stopper and the step coverage compensation patterns; forming a passivation layer covering the substrate having the data line and the source and drain electrodes; and forming a common electrode on the passivation layer.
