Patent ID: 7524711

Claim:
A method of manufacturing an image TFT array for an indirect X-ray sensor, comprising: providing a substrate; applying a first conductive layer covering the substrate; defining at least one first line, a lower electrode, a pad electrode, a common electrode and a first electrode connected with the first line simultaneously by etching the first conductive layer; forming an insulation layer covering the substrate, the first line, the lower electrode, the pad electrode, the common electrode and the first electrode; applying a second conductive layer covering the insulation layer; defining at least one second line intersecting the first line, an upper electrode corresponding to the lower electrode, a second electrode connected with the second line, a third electrode connected with the upper electrode, a first through hole corresponding to the common electrode to expose the insulation layer, and a second through hole corresponding to the pad electrode to expose the insulation layer simultaneously by etching the second conductive layer; applying a passivation layer covering the second conductive layer and on the insulation layer exposed by the first and the second through holes; and defining an aperture exposing a portion of the upper electrode and making the first and the second through holes deep to expose the common electrode and the pad electrode simultaneously by etching the passivation layer and the insulation layer.
