Patent ID: 8890304

Claim:
A microelectronic package, comprising: a microelectronic unit, including: a microelectronic element having a front face, edges bounding the front face, and contacts on the front face; a dielectric material having a first surface substantially flush with the front face of the microelectronic element and extending away from the edges thereof; conductive traces having at least portions extending along the front face away from the contacts, at least some of which also extend along the first surface of the dielectric material; and conductive redistribution contacts connected with the traces, at least some of which are disposed at the first surface of the dielectric material; a substrate having first and second opposed surfaces and an edge extending therebetween, the first surface facing the front face of the microelectronic unit, and the second surface having a plurality of terminals thereon configured for electrical connection with at least one external component; and conductive interconnects including masses of conductive matrix material joined to the redistribution contacts and electrically connected with the terminals, wherein the conductive matrix material comprises a high melting point material, a low melting point material, and a polymer.
