Abstract: Provided is a method of crystallizing an amorphous silicon thin film transistor and a method of fabricating a polycrystalline thin film transistor using the same, in which the polycrystalline thin film transistor indicating leakage current characteristics of a level that is applicable for active matrix organic light emitting diode displays (AMOLEDs) can be manufactured by using a silicide seed induced lateral crystallization (SILC) method.

Abstract: Provided is an electroplating apparatus including: a water tank that is filled with a non-polar solvent having a higher specific gravity than an electrolyte in which an electrolyte layer is formed on top of the non-polar solvent; a copper electrode that is installed at a portion where the electrolyte layer of the water tank is positioned; an insulating substrate that is disposed to be inserted into and withdrawn from the water tank and on which seed electrodes are formed; an actuator that escalates the insulating substrate up and down; and a power supply that applies electric current between the copper electrode and each of the seed electrodes, to thereby uniformly form thickness of a metal thin film on a large substrate and guarantee grain size.
