Abstract
Abstract A multi-chip-module comprising a plurality of vertically layered substrates and including a plurality of coaxial inter-connects formed between and through the substrate layers. Each of the coaxial inter-connects is formed by a process wherein: an outer hole (aperture) is drilled through the substrate and lined with an electrically conductive material to form an outer via; the outer via is filled with a dielectric material; and, an inner hole (aperture) is drilled through the dielectric material and filled with an electrically conductive material to form a center via. The characteristic impedance of the coaxial inter-connect is determined by the selection of the outer diameters of the drilled holes for the outer and center vias.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
85 words
A method for manufacturing a coaxial interconnect, comprising the steps of: forming an outer aperture through a substrate layer; coating an inner surface of the outer aperture in the substrate layer with an electrically conductive material to form an outer conductor of the coaxial inter-connect; filling the coated outer aperture with a dielectric material; forming an inner aperture through the dielectric material; and filling the inner aperture in the dielectric material with an electrically conductive material to form a center conductor of the coaxial inter-connect.
Claim 2
Independent Claim
85 words
A method for manufacturing a coaxial interconnect, comprising the steps of: forming an outer aperture through a substrate layer; coating an inner surface of the outer aperture in the substrate layer with an electrically conductive material to form an outer conductor of the coaxial inter-connect; filling the coated outer aperture with a dielectric material; forming an inner aperture through the dielectric material; and filling the inner aperture in the dielectric material with an electrically conductive material to form a center conductor of the coaxial inter-connect.
Claim 3
Dependent Claim
54 words
The method as in claim 1 wherein the outer aperture in the substrate layer has a first outer diameter and the inner aperture in the dielectric material has a second outer diameter, further including the step of: selecting the first and second outer diameters to establish a predetermined characteristic impedance for the coaxial inter-connect.
Claim 4
Dependent Claim
38 words
The method as in claim 1 wherein the step of filling the inner aperture in the dielectric material comprises the step of inserting a fuzz-button through the inner aperture to form the center conductor of the coaxial inter-connect.
Claim 5
Dependent Claim
35 words
The method as in claim 1 wherein the step of filling the inner aperture in the dielectric material comprises the step of coating an inner surface of the inner aperture with an electrically conductive material.
