One aspect of the invention relates to a method for fabricating a polycrystalline silicon film. In one embodiment, the method includes the steps of providing a substrate having a thermally-grown silicon dioxide layer, forming an amorphous silicon film on the thermally-grown silicon dioxide layer of the substrate, forming an aluminum layer on the amorphous silicon film to form a structure having the substrate, the amorphous silicon film and the aluminum layer, and annealing the structure at an annealing temperature for a period of time in an N2 environment with a ramp-up time to crystallize the amorphous silicon film to form a polycrystalline silicon film.
