Method of fabricating polycrystalline silicon thin film

Image Number 3 for United States Patent #8367527.

A method of fabricating a polycrystalline silicon thin that includes a metal layer forming operation of forming a metal layer on an insulating substrate, a first silicon layer forming operation of stacking a silicon layer on the metal layer formed in the metal layer forming operation, a first annealing operation of forming a silicide layer using by moving catalyst metal atoms from the metal layer to the silicon layer using an annealing process, a second silicon layer forming operation of stacking an amorphous silicon layer on the silicide layer, and a crystallization operation of crystallizing the amorphous silicon layer into crystalline silicon through the medium of particles of the silicide layer.
