Patent ID: 7301108

Claim:
A multi-layered interconnect structure, comprising: a thermally conductive layer including first and second opposing surfaces; a first liquid crystal polymer (LCP) dielectric layer directly bonded to the first opposing surface of the thermally conductive layer with no extrinsic adhesive material bonding the first LCP dielectric layer to the thermally conductive layer; a second LCP dielectric layer directly bonded to the second opposing surface of the thermally conductive layer with no extrinsic adhesive material bonding the second LCP dielectric layer to the thermally conductive layer; a first electrically conductive layer within the first LCP dielectric layer; and a second electrically conductive layer within the first LCP dielectric layer and positioned between the first electrically conductive layer and the thermally conductive layer, and heating the first and second LCP layers being bonded to the first and second opposing surfaces, respectively, to a temperature less than a liquid crystal transition temperature, and said second electrically conductive layer comprising a first plurality of shielded signal conductors; first and second pluralities of electrically conductive members positioned on the first and second LCP dielectric layers, respectively; a plated through hole through the multi-layered interconnect structure electrically connected to at least one member of the first plurality of electrically conductive members, to at least one of the first plurality of shielded signal conductors, and to at least one member of the second plurality of electrically conductive members; and a third dielectric layer positioned on said first dielectric layer and on portions of said first plurality of electrically conductive members, said third dielectric layer substantially overlying said plated through hole, and wherein said third dielectric layer includes a high density interconnect layer for providing an electrical path from a first electronic device to the first plurality of shielded signal conductors.
