The method includes steps of: forming an active layer pattern which has a mobility greater than a predetermined threshold from an active layer material; and performing ion implantation on the active layer pattern. The energy of a compound bond formed from the implanted ions is greater than that of a compound bond formed from ions in the active layer material, thereby reducing the chance of vacancy formation and reducing the carrier concentration. Therefore, the mobility of the active layer surface is reduced, the leakage current is reduced, the threshold voltage is adjusted to shift toward positive direction and performance of the thin film transistor is improved.
