Abstract: A microelectronic component with circuitry includes a substrate (possibly semiconductor) having an opening in a top surface. The circuitry includes a conductive via (possibly metal) in the opening. The opening has a first sidewall of a first material, and the conductive via has a second sidewall of a second material (possibly metal). 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. Between the meeting location and the top surface of the substrate, the first and second sidewalls are separated by a third material (possibly foam) which is a dielectric different from the first material. The third material lowers thermal stress in case of thermal expansion compared to a structure in which the third material were replaced with the second material.

Abstract: A component can include a substrate and a conductive via extending within an opening in the substrate. The substrate can have first and second opposing surfaces. The opening can extend from the first surface towards the second surface and can have an inner wall extending away from the first surface. A dielectric material can be exposed at the inner wall. The conductive via can define a relief channel within the opening adjacent the first surface. The relief channel can have an edge within a first distance from the inner wall in a direction of a plane parallel to and within five microns below the first surface, the first distance being the lesser of one micron and five percent of a maximum width of the opening in the plane. The edge can extend along the inner wall to span at least five percent of a circumference of the inner wall.
