【 摘 要 】

This work focuses on directly photodefinable polymeric materials with lower dielectric constants and improved lithographic properties. Two materials were investigated. One material uses diazonaphthoquinone as the photo active compound with a polynobornene backbone polymer matrix. Epoxy was used to mitigate base uptake and allow cross-linking through both the multi-functional epoxy and the bis(diazonaphthoquinone). The second material uses low ceiling temperature polyaldehydes for packaging applications that have catalytic responses to small triggers.An in-situ NMR method for determining thermodynamic variables of low ceiling temperature polymers was established. The choice of polyaldehyde monomers was also considered for use in dry-developing applications. The dry-developing phenomenon will be utilized for the triggered disappearance of a polymer in a printed wiring board.
