Abstract:
A LTPS TFT comprises a substrate, and a buffer layer, a low temperature polysilicon layer, a source contact area, a drain contact area, a gate insulating layer, a gate layer, a dielectric layer, a source and a drain disposed on the substrate successively. The source contact area and the drain contact area are doped with metal ions individually. The source and the drain are connecting with the source and drain contact areas separately through the dielectric layer. The metal ions include at least one of Cu 2+ , Al 3+ , Mg 2+ , Zn 2+  and Ni 2+ . A method of fabricating the LTPS TFT is also provided. An annealing is performed for driving individually metal ions of the insulation metal oxide layer into the source contact area and the drain contact area. Thus, the step of implanting p-type ions can be omitted, the procedure can be significantly simplified, and the manufacturing cost can be reduced.

Claim (Index 7):
The method of forming the LTPS TFT according to  claim 3 , further comprising:\n depositing a dielectric layer on the gate layer to cover the gate layer and the insulation metal oxide layer before forming the source and the drain; performing a dry etching to form a first contact hole and a second contact hole passing through the dielectric layer and the insulation metal oxide layer, for exposing the source contact area and the drain contact area separately; and forming the source connecting with the source contact area through the first contact hole and the drain connecting with the drain contact area through the second contact hole on the dielectric layer.
