  • Photodefinable dielectric layers comprising poly(aromatic diacetylenes)
    Patent number: 5589424
    Abstract: 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/cm.sup.2 .mu.m and 60 mJ/cm.sup.2 .mu.m, respectively, and patterns have been produced in 10 .mu.m thick films with features as small as 12 .mu.m.
    Type: Grant
    Filed: October 17, 1995
    Date of Patent: December 31, 1996
    Assignee: Lucent Technologies Inc.
    Inventors: Elizabeth W. Kwock, Timothy M. Miller
