Abstract:
A method of fabricating a thin film transistor for an X-ray detector, comprising:forming a gate line, a gate pad and a gate electrode of the thin film transistor simultaneously on a substrate; forming a first insulating layer over the gate line, gate pad and gate electrode; forming a semiconductor layer over the first insulating layer; forming a data pad, a data line, source and drain electrodes of the thin film transistor and a ground electrode simultaneously; forming a first electrode for a charging capacitor; forming a second insulating layer for the charging capacitor; forming a second electrode for preventing an etching of the second insulating layer for the charging capacitor; forming a protective film for protecting the thin film transistor; forming contact holes in the protective film; and forming a pixel electrode connected to the thin film transistor.
