Method and apparatus for pellicle removal
Abstract:
A method and apparatus for removing a pellicle from a photomask wherein the adhesive between the pellicle frame and photomask is cooled sufficiently to allow the adhesive property of the adhesive to diminish to the point where the adhesive will release from the photomask with little or no mechanical force and leaving minimal adhesive on the photomask. The adhesive is cooled by way of manifolds containing coolant being brought in contact with the pellicle frame or by way of a coolant spray nozzles spraying coolant directly onto the pellicle frame.
