Patent ID: 8709933

Claim:
An interconnection component, comprising: a plurality of substantially rigid solid metal posts each having a first end surface, a second end surface remote from the first end surface, and an edge surface extending between the first and second end surfaces, each post extending in a direction normal to the end surfaces, each post being a single monolithic metal region throughout and at the edge surface; and a dielectric layer having a coefficient of thermal expansion of less than 8 parts per million per degree Celsius (ppm/° C.) directly contacting the edge surfaces and filling spaces between adjacent ones of the posts, the dielectric layer having a first and second opposed surfaces adjacent the first and second end surfaces, the first and second surfaces extending in lateral directions, the interconnection component having no electrically conductive interconnects between the first and second end surfaces of the posts that extend in a lateral direction, the interconnection component having first and second pluralities of wettable contacts adjacent the first and second opposed surfaces, respectively, the first and second wettable contacts being usable to bond the interconnection element to at least one of a microelectronic element and a circuit panel, at least one of the first wettable contacts or the second wettable contacts matching a spatial distribution of element contacts at a face of a microelectronic element and at least one of the first wettable contacts or the second wettable contacts matching a spatial distribution of circuit contacts exposed at a face of a circuit panel.
