Abstract:
A method for fabricating an X-ray image detecting device, the method comprising;forming a gate element on a substrate; forming a gate insulating layer on the substrate and covering the gate element; forming an ohmic contact layer on a portion of the gate insulating layer above the gate element; forming source and drain electrodes on the ohmic contact layer simultaneously with forming a first common electrode on the gate insulating layer; forming a storage capacitor insulating layer on the source and drain electrodes and the first common electrode; forming a first contact hole through the storage capacitor insulating layer so as to expose a portion of the drain electrode; forming a second contact hole through the storage capacitor insulating layer so as to expose a portion of the first common electrode; forming a sensing electrode on the storage capacitor insulating layer, the sensing electrode contacting the drain electrode through the first contact hole; and forming a second common electrode on the storage capacitor insulating layer such that the second common electrode covers the gate element, such that the second common electrode extends over the source and drain electrodes, and such that the second common electrode contacts the first common electrode through the second contact hole.
