To provide a method of separating a pellicle and a device for separating a pellicle which can reduce the amount of residue left on an exposure original plate when the pellicle is separated from the exposure original plate and which can wash again the exposure original plate under mitigated washing conditions, a pellicle frame support pin is inserted into a jig hole provided in an outer surface of the pellicle frame, the pellicle frame support pin is moved in a direction in which the pellicle is separated from the exposure original plate, a separation force applied by the movement to the pellicle frame support pin is measured and the pellicle is separated from the exposure original plate while control is being performed such that the separation force is minimized.

Embodiments of the present disclosure generally provide apparatus and methods for removing an attachment feature utilized to hold a pellicle from a photomask. In one embodiment, an attachment feature removal apparatus for processing a photomask includes an attachment feature puller comprising an actuator, a clamp coupled to the actuator, the clamp adapted to grip an attachment feature, and a coil assembly disposed adjacent to the attachment feature.
