Abstract:
There is provided a method for preparing a graphene film for pellicle, and also a method for making a pellicle using such graphene film: wherein a film-like graphene deposited on a base material is coated with a protective film, from which the base material is chemically removed by an etching liquid and then the protective film is chemically removed by a solvent whose surFace tension is lower than that of the etching liquid; the pellicle frame may be attached to the film-like graphene before the protective film is completely removed or thereafter.
