    摘要: A photosensitive dielectric composition adapted for forming a dielectric film layer for use in a circuitized substrate is provided according to one embodiment of the invention, the composition including an epoxide bearing component including at least one polyepoxide resin curable by electromagnetic radiation, a cyanate ester, a flexibilizer, a nanostructured toughener, a photoinitiator in a predetermined amount by weight of the resin component, and a ceramic filler, the photosensitive dielectric composition forming the dielectric film layer having no solvent therein. In an alternative embodiment, a heat activated dielectric composition is provided which is curable by heat and includes an epoxide bearing component including at least one polyepoxide resin curable by heat, a cyanate ester, a flexibilizer, a nanostructured toughener, a heat activated curing agent for accelerating reaction of the cyanate ester and polyepoxide resin components, and a ceramic filler. Methods of making circuitized substrates from the above compositions are also provided.
