Claim:
1. A separation apparatus for separating a stacked article comprising a substrate and a cap layer formed on the substrate, comprising: a vacuum nozzle head, comprising a suction pad having a top surface and a bottom surface, a through hole penetrating the top surface and the bottom surface of the suction pad, and a hollow vacuum pipe connecting the through hole to a vacuum pump; a stage, positioning under the vacuum nozzle head and substantially aligning with the suction pad; a control means, coupling to the vacuum nozzle head to lift upward or lower down the vacuum nozzle head; and a first cutter, comprising a first cutting body and a first knife connecting to the first cutting body; wherein, the cap layer is pressed by the bottom surface of the suction pad and the stacked article is sucked by the vacuum nozzle head after the vacuum pump begins to vacuum the air within the hollow vacuum pipe, then the first cutter cuts into the interface between the substrate and the cap layer, and the cap layer is separated from the substrate by the suction force of the vacuum nozzle head and the lift force generated by the upward movement of the vacuum nozzle head.
