Circuit structures and methods of forming circuit structures with minimal dielectric constant layers

摘要

An apparatus including a contact point formed on a device layer of a circuit substrate or an interconnect layer on the substrate; a first dielectric material; and a different second polymerizable dielectric material on the substrate and separated from the device layer or the interconnect layer by the first dielectric material following polymerization, the second dielectric material comprising a glass transition temperature of at least 250° C. and a thermal decomposition temperature of at least 400° C. A method including depositing a dielectric material and thermally treating the dielectric material at a temperature greater than the thermal decomposition temperature.
