Patent ID: 8367527

Claim:
A method of fabricating a polycrystalline silicon (poly-Si) thin film, the method comprising: a metal layer forming operation of forming a metal layer on an insulating substrate; an oxide layer forming operation of forming a metal oxide layer on a surface of the metal layer by annealing the metal layer or by depositing the metal oxide layer; a first silicon layer forming operation of stacking a silicon layer on the metal oxide layer formed in the oxide layer forming operation; a first annealing operation of forming a silicide layer by moving metal catalyst atoms from the metal layer to the first silicon layer using an annealing process; a second silicon layer forming operation of stacking an amorphous silicon (a-Si) layer on the silicide layer; and a crystallization operation of crystallizing the a-Si layer into a crystalline silicon layer through the medium of particles of the silicide layer using an annealing process.
