  • Publication number: 20230341763
    Abstract: Disclosed is a pellicle including a pellicle membrane including a carbon-based membrane having a carbon content of 40% by mass or more and a support frame that supports the pellicle membrane, in which the pellicle membrane and the support frame are in contact with each other, and at least one of the following conditions 1 and 2 is satisfied. [Condition 1] In the support frame, a surface in contact with the pellicle membrane has a roughness Ra of 1.0 ?m or less. [Condition 2] The support frame has a width of unevenness of 10 ?m or less at an edge portion on a surface side in contact with the pellicle membrane and on an inner side of the pellicle.
