| 摘要 |
A method for manufacturing a polysilicon type thin film transistor comprises the steps of forming a polysilicon layer on a substrate, forming a gate insulating layer on the polysilicon layer, forming a gate layer on the gate insulating layer, forming a gate pattern by patterning, implanting impurities in the substrate over which the gate pattern is formed, forming a cover layer over the substrate in which impurities are implanted, and thermally annealing the substrate over which the cover layer is formed. In the invention, the thermal annealing carried out instead of a costly laser annealing after the impurity implantation.
