Abstract:
A method for fabricating a thin film transistor array and a driving circuit, comprising the steps of:providing a substrate; sequentially forming a polysilicon layer and a thin film over the substrate, wherein the thin film is a first type heavily doped layer; patterning the polysilicon layer and the thin film to form a plurality of island structures; forming a second type heavily doped region in a portion of the thin film in the island structure; forming a gate and a source/drain terminal on each island structure and forming a storage capacitor on the substrate, wherein the gate, the source/drain terminal and the island structure together form a thin film transistor array and a driving circuit; forming a protection layer over the substrate; patterning the protection layer to form a plurality of openings in the protection layer; forming a conductive layer over the substrate; and patterning the conductive layer to form a plurality of wiring lines and a plurality of pixel electrodes, wherein the wiring lines serves as a connection between the thin film transistor in the array and the driving circuits.
