Abstract
Thin dielectric films are formed on an electronic component by in situ curing a polymerizable oligomer which is end capped with vinyl and/or acetylenic end groups. The polymerizable oligomers are comprised of polyamic acids, polyamic esters, polyisoimides, and mixtures thereof which can be crosslinked to form a three-dimensional network via sites at the vinyl or acetylenic end groups and sites at carbonyl groups contained within the polymeric chain. Use of these polymerizable oligomers permits utilization of low temperature methods of curing which reduce intrinsic and extrinsic stress within the cured dielectric film.
