Patent ID: 8394557

Claim:
A lithographic pellicle, comprising a pellicle frame having a top end, a bottom end, and an inner wall, a pellicle film stretched across and mounted to said pellicle frame at its top end, a pressure-sensitive adhesive layer disposed on the bottom end of said pellicle frame, capable of attaching said pellicle frame to a substrate, and an inner pressure-sensitive adhesive layer disposed on the inner wall of said pellicle frame and made of a curable composition comprising a perfluoro compound having a perfluoro structure backbone in a cured state, wherein said curable composition comprises: (A) a perfluoro compound having a perfluoroalkylene or perfluoropolyether structure in the backbone, having at least 2 alkenyl groups in the molecule, (B) a perfluoro compound having a perfluoroalkyl or perfluoropolyether structure in the backbone, having one alkenyl group in the molecule, an organosilicon compound having at least two hydrosilyl groups (SiH groups) in the molecule, and a platinum group metal catalyst.
