  • Publication number: 20240377726
    Abstract: The present disclosure provides a pellicle that includes: a pellicle frame; a pellicle film supported at one end surface of the pellicle frame; and an adhesive layer provided at another end surface of the pellicle frame, and satisfies the following Equation (1): [A60° C.]?4.0 gf/mm2 (1). In Equation (1), [A60° C.] represents a first peel strength when the pellicle is used in a test laminated body. The test laminated body is obtained by placing the pellicle on a quartz glass substrate such that the adhesive layer is in contact with a surface of the quartz glass substrate, and maintaining a load on the pellicle under prescribed conditions. The first peel strength represents a load per unit adhesion area, which load is required for peeling the pellicle included in the test laminated body from the quartz glass substrate using a standard universal tester under prescribed conditions.
