Abstract
A conductive network fabrication process is provided and includes filling a hole formed in a substrate with dielectric material, laminating films of the dielectric material on either side of the substrate, opening a through-hole through the dielectric material at the hole, depositing a conformal coating of dielectric material onto an interior surface of the through-hole and executing seed layer metallization onto the conformal coating in the through-hole to form a seed layer extending continuously along an entire length of the through-hole.
