A method for minimizing damage to a substrate while repairing a defect in a phase shifting mask for an integrated circuit comprising locating a bump defect in a phase shifting mask, depositing a first layer of protective coating to an upper surface of the bump defect, depositing a second layer of protective coating to areas of the phase shifting mask adjacent the bump defect, etching the first layer of protective coating and removing the bump defect.
