Claim 12:
13. A manufacturing method for a thin film transistor, comprising:
S1: forming an aluminum film on a substratum through magnetron sputtering;
S2: placing the substratum with the aluminum film in a reaction chamber of an atomic layer deposition apparatus;
S3: continuously introducing a molybdenum precursor for a preset time period into the atomic layer deposition apparatus, remaining for a preset time period after the introduction, and introducing an inert gas for purging;
S4: continuously introducing a reducing gas for a preset time into the atomic layer deposition apparatus, remaining for a preset time period after the introduction, and introducing the inert gas for purging;
S5: repeating the steps S3 and S4 for a preset number of times to form a molybdenum film;
S6: etching the aluminum film and the molybdenum film to form the gate electrode of a predetermined pattern; and
S7: sequentially forming an insulating layer, a semiconductor layer, source and drain electrodes and a passivation layer above the gate electrode to form the thin film transistor.
