METHOD FOR MANUFACTURING N-TYPE TFT

The present invention provides a method for manufacturing the N-type TFT, which includes subjecting a light shielding layer to a grating like patternization treatment for controlling different zones of a poly-silicon layer to induce difference of crystallization so as to have different zones of the poly-silicon layer forming crystalline grains having different sizes, whereby through just one operation of ion doping, different zones of the poly-silicon layer have differences in electrical resistivity due to difference of grain size generated under the condition of identical doping concentration to provide an effect equivalent to an LDD structure for providing the TFT with a relatively low leakage current and improved reliability. Further, since only one operation of ion injection is involved, the manufacturing time and manufacturing cost can be saved, damages of the poly-silicon layer can be reduced, the activation time can be shortened, thereby facilitating the manufacture of flexible display devices.
