Abstract: Pellicles having films bearing at least one coating of perfluoropolymers as an antireflective surface, the perfluoropolymers comprising a low molecular weight perfluoropolymer having randomly copolymerized units of tetrafluoroethylene, perfluoro (alkyl vinyl) ether and a cure site monomer, the cure site monomer selected from the group consisting of vinylidene fluoride, perfluoro-(8-cyano-5-methyl-3,6-dioxa-1-octene), bromotetrafluorobutene or perfluoro (2-phenoxypropyl vinyl ether). Pellicles of this type are dust defocusing covers for photomasks and reticles used to project patterns onto light sensitive substrates such as photoresist-coated semiconductor wafers which are used in the manufacture of integrated circuits.
