Claim:
1. A component having first and second opposite sides, comprising: a first element having a first surface coincident with or adjacent to the first side of the component, and a second surface opposite the first surface, the first element comprising a first material having a coefficient of thermal expansion of less than 10 ppm/° C.; a second element coupled to the second surface of the first element and having a surface coincident with or adjacent to the second side of the component, the second element comprising electrically insulated structures formed of at least one second material different from the first material, each of the insulated structures at least partially separated from one another by at least one gap extending from the surface of the second element towards the first element; a plurality of conductive elements at the first side; a plurality of terminals at the second side, the terminals configured for connection with a plurality of corresponding contacts of a another component external to the component; and conductive structure electrically coupling the plurality of terminals with the plurality of conductive elements, the conductive structure including at least one electrically conductive interconnect within an opening extending through at least one of the insulated structures towards the first element, the conductive structure including a conductive via extending within the first element in a first direction of a thickness of the first element, a conductive pad at the second surface of the first element, the conductive pad in contact with the conductive via and aligned at least partially with the opening, and conductive material extending within the opening and contacting the conductive pad, wherein the insulated structures define a plurality of the gaps, and the gaps define a plurality of islands fully separated from one another by the gaps in a first direction parallel to the second surface and in a second direction parallel to the second surface and transverse to the first direction, each island including at least one of the insulated structures, the islands being disposed in a grid pattern, and wherein the opening defines a first maximum aspect ratio of a length in a third direction perpendicular to the second surface to a width in the first or second direction, and the conductive via defines a second maximum aspect ratio of a length in the third direction to a width in the first or second directions, the first maximum aspect ratio being greater than the second maximum aspect ratio.
