Abstract:
1. A method of manufacturing a low temperature polysilicon film, comprising the steps of: forming a first metal layer on a substrate, a plurality of openings contiguous to the substrate being formed in the first metal layer; forming a second metal layer on the first metal layer by performing an oblique evaporation and a hole being formed in the second metal layer corresponding to each of the openings; forming a silicon layer on the second metal layer and a silicon seed being formed on the substrate inside each of the holes, wherein a size of the silicon seed is in a range of about 0.5 μm to 1.0 μm; removing the first metal layer and the second metal layer; forming an amorphous silicon layer on the substrate by using the silicon seed for performing a deposition process; and transforming the amorphous layer to a polysilicon layer by performing a crystallization.
