摘要:
A method and apparatus are disclosed for removing a pellicle frame (52) from a photomask plate (50) where the pellicle frame (52) is adhered to a surface of the photomask plate (50) by an adhesive material (54). Tension is applied to the adhesive material (54) by applying force to separate the pellicle frame (52) and the photomask plate (50). A second surface of the photomask plate (50), opposite from the surface to which the pellicle frame (52) is adhered, is heated to raise the temperature of the adhesive material (54) and to raise the temperature of the photomask plate (50) greater than the temperature of the pellicle frame (52). The tension on the adhesive material (54) is then maintained until the adhesive material (54) releases the pellicle frame (52) from the photomask plate (50).
