摘要: Applicants have discovered an improved photodefined dielectric materials comprising poly(aromatic diacetylenes). The preferred poly(aromatic diacetylenes) are copolymers of aromatic diacetylenes. Specific examples are 1) a copolymer of 4,4'-diethynyldiphenyl ether and m -diethynyl benzene and 2) a copolymer of 4,4'-diethynyldiphenyl ether and 4,4'-bis(3-ethynylphenoxy)-2,2',3,3',5,5',6,6'-octafluorobiphenyl. These copolymers can be photochemically crosslinked in patterns with exposure of 30 mJ/cm²µm and 60 mJ/cm²µm, respectively, and patterns have been produced in 10 µm thick films with features as small as 12 µm.
