INTERCONNECTION ELEMENTS WITH ENCASED INTERCONNECTS

摘要

An interconnection element is disclosed that includes a plurality of drawn metal conductors, a dielectric layer, and opposed surfaces having a plurality of wettable contacts thereon. The conductors may include grains having lengths oriented in a direction between the first and second ends of the conductors. A dielectric layer for insulating the conductors may have first and second opposed surfaces and a thickness less than 1 millimeter between the first and second surface. One or more conductors may be configured to carry a signal to or from a microelectronic element. First and second wettable contacts may be used to bond the interconnection element to at least one of a microelectronic element and a circuit panel. The wettable contacts may match a spatial distribution of element contacts at a face of a microelectronic element or of circuit contacts exposed at a face of component other than the microelectronic element.
