A METHOD OF MANUFACTURING A PELLICLE FOR A LITHOGRAPHIC APPARATUS, A PELLICLE FOR A LITHOGRAPHIC APPARATUS, A LITHOGRAPHIC APPARATUS, A DEVICE MANUFACTURING METHOD, AN APPARATUS FOR PROCESSING A PELLICLE, AND A METHOD FOR PROCESSING A PELLICLE

摘要

Methods of manufacturing a pellicle for a lithographic apparatus are disclosed. In one arrangement the method comprises depositing at least one graphene layer (2) on a planar surface (4) of a substrate (6). The substrate comprises a first substrate portion and a second substrate portion (12). The method further comprises removing the first substrate portion to form a freestanding membrane (14) from the at least one graphene layer. The freestanding membrane is supported by the second substrate portion.
