Patent ID: 7348496

Claim:
An article of manufacture, comprising: a substrate; a hole through the substrate, a portion of the surface of the substrate surrounding the hole plated with a first conductive material; a dielectric layer formed over the first conductive material in the through hole and defining a smaller through hole coaxially aligned with the through hole; the dielectric layer comprising high dielectric constant material; a conductor formed of a second conductive material in the smaller through hole; and an insulating layer formed over the hole and at least a portion of the first conductive material; and having at least two microvias formed therein, one of the microvias electrically coupled to the first conductive material with which the through hole is plated and another of the microvias electrically coupled to the conductive material in the smaller through hole; one of the first and second conductive materials coupled to a ground layer of the article, and the other of the first and second conductive materials connected to a voltage supply layer of the article, to form a capacitor coupling the ground layer and voltage supply layer.
