Abstract

Embodiments of the present invention include forming a thin, conformal, high-integrity dielectric coating between conductive layers in a via-in-via structure in an organic substrate, using an electrocoating process to reduce loop inductance between the conductive layers. The dielectric coating is formed using a high dielectric constant material such as an organic polymer or an organic polymer mixture. Embodiments of the present invention also include forming a thin, dielectric coating between conductive layers on a substantially planar substrate material and providing an embedded capacitor to reduce loop inductance.
