Laser bonding apparatus and method

The present invention relates to a method for formation of a redistribution layer using photo-sintering and to the redistribution layer formed by the method. The method for forming a redistribution layer using photo-sintering includes printing, on a substrate, a liquid electrode pattern for a redistribution layer; coating a transparent polymer on the substrate and the pattern; photo-sintering the electrode pattern using photonic energy; and evaporating an organic substance contained in the liquid electrode pattern via the photo-sintering to remove the polymer on a top face of the electrode pattern to form a redistribution layer as the sintered electrode pattern.
