Abstract:
A method for manufacturing an x-ray detector having an insulating substrate, the method consisting the six sequential steps of:forming a gate and a pad on the insulating substrate; forming a gate insulating film over a selected area of the insulating substrate having the gate and the pad, forming an amorphous silicon layer over the insulating substrate and forming an etch stopper over the amorphous silicon layer forming a channel layer, an ohmic contact layer and a source/drain over the gate insulating film which includes the etch stopper, and forming a common electrode over a proper portion of the gate insulating film simultaneously; forming a first storage electrode over the gate insulating film which includes the common electrode; before forming a second storage electrode, forming a protective layer over the entire structure of the insulating substrate on which the source/drain and the first storage electrode have been formed, and subsequently forming a contact hole and via holes over a proper portion of the protective layer; and forming the second storage electrode over the protective layer.
