Claim Text:
1. A method for making a microelectronic component, the method comprising: providing a substrate comprising an opening in a top surface, the substrate forming part of the microelectronic component; and forming a conductive via in the opening, the conductive via forming at least part of circuitry of the microelectronic component; wherein the opening comprises a first sidewall of a first material, and the conductive via comprises a second sidewall of a second material; wherein at least at one side of the opening, the first and second sidewalls are spaced from each other at the top surface of the substrate but the first and second sidewalls meet below the top surface of the substrate at a meeting location, and between the meeting location and the top surface of the substrate the first and second sidewalls are separated by a third material which is a dielectric different from the first material.
