    Abstract: The present invention is directed to prevent generating repair by-products during a repair process of a phase shift mask, and defects on a quartz substrate. According to the present invention, a repair method for phase shift mask in a semiconductor device so as to remove a bridge formed between a phase shift layer on a quartz substrate, comprises the steps of: first repairing the bridge by implanting a charging ion according to a focused ion beam(“FIB”) method; and second repairing the first repaired bridge portion by emitting laser and then removing the bridge.
