摘要： A method of fabricating a thin film transistor substrate for an X-ray detector reduces the number of steps in etching processes using masks. In the method, a gate line, a gate pad and a gate electrode of a thin film transistor are simultaneously formed on a certain substrate. A gate insulating layer is entirely coated, and then a semiconductor layer of the thin film transistor is formed. A data pad, a data line, source and drain electrodes of the thin film transistor and a ground electrode are simultaneously formed. An electrode for a charging capacitor is formed, and then an insulating film for the charging capacitor is formed. An electrode for preventing an etching of the insulating film for the charging capacitor is formed. A protective film for protecting the thin film transistor is formed. Contact holes are formed in the protective film. Finally, a pixel electrode is provided. Accordingly, the data pad and the data line are formed of a molybdenum metal and at the same layer, and the molybdenum layers of the data pad and the gate pad are connected to the driver IC chip using the wire bonding technique. As a result, the present method is capable of reducing nine-step mask etching processes in the prior art to a seven-step mask etching processes.
