Abstract:
1. A thin film transistor manufacturing method, characterized in that, comprising steps of: providing a transparent substrate; forming a gate electrode and a data line on a surface of the transparent substrate; forming a first insulation layer, which covers the gate electrode and the data line, on the surface of the transparent substrate; forming an amorphous semiconductor layer on a surface of the first insulation layer in an area corresponding to the gate electrode; forming a through hole in an area of the surface of the first insulation layer corresponding to the data line; forming a conductive layer, which covers the amorphous semiconductor layer and the through hole, on the surface of the first insulation layer; removing a portion of the conductive layer corresponding to the gate electrode to cut the conductive layer, thereby forming a source electrode and a drain electrode of the thin film transistor; forming a second insulation layer, which covers the amorphous semiconductor layer, the through hole, as well as the source electrode and the drain electrode, on the surface of the first insulation layer; removing a portion of the second insulation layer located between the source electrode and the drain electrode; and irradiating the amorphous semiconductor layer by a laser to increase an ordering degree of a lattice of the amorphous semiconductor layer.
