Abstract

Abstract A planarizing dielectric, which is particularly suitable for electronic components, fulfills the required properties to a high degree when it comprises a matrix of a high-temperature resistant, organic polymer, into which matrix is intercalated in fine distribution a solid filler material, which is etchable in oxygen plasma, has high thermal conductivity and good dielectric properties.
