Patent ID: 8604348

Claim:
A packaged microelectronic assembly comprising: a microelectronic element having a plurality of contacts exposed at a face thereof; and a connection component including: a first conductive layer having portions joined to the contacts of the microelectronic element; a reinforced dielectric layer; a compliant dielectric layer, wherein the reinforced dielectric layer is between the compliant dielectric layer and the first conductive layer, and wherein the portions of the first conductive layer are at a surface of the reinforced dielectric layer remote from the compliant dielectric layer; a plurality of first conductive connectors extending in the form of a post from a surface of the first conductive layer facing the surface of the reinforced dielectric layer through the reinforced dielectric layer; and a plurality of second conductive connectors extending through the compliant dielectric layer, wherein the first conductive connectors are electrically connected to the portions of the first conductive layer and the second conductive connectors.
