MULTILAYER ELECTRONIC STRUCTURE WITH THROUGH-THICKNESS COAXIAL STRUCTURES

摘要

PROBLEM TO BE SOLVED: To provide a multilayer electronic structure which comprises coaxial structures and has excellent electric characteristics.SOLUTION: A multilayer electronic structure 300 comprises: a plurality of dielectric layers 302 extending in an X-Y plane; and at least one coaxial pair of stacked posts 304 extending through at least one dielectric layer in a Z direction that is substantially perpendicular to the X-Y plane. The coaxial pair of stacked via posts comprise a central post 306 surrounded by a toroidal via post 308 separated from the central post by a separating tube 310 of dielectric material.
