Patent ID: 7329816

Claim:
A multi-layered interconnect structure, comprising: a thermally conductive layer including first and second opposing surfaces; a first dielectric layer laminated to said first opposing surface of said thermally conductive layer such that the first dielectric layer includes a first dielectric material and has a ductility of at least about D 1 ; a second dielectric layer laminated to said second opposing surface of said thermally conductive layer such that the second dielectric layer includes a second dielectric material and has a ductility of at least about D 2 ; first and second pluralities of electrically conductive members positioned on said first and second dielectric layers, respectively; a first electrically conductive layer within said first dielectric layer; a second electrically conductive layer within said first dielectric layer and positioned between said first electrically conductive layer and said thermally conductive layer, wherein said second electrically conductive layer comprises a first plurality of shielded signal conductors; a plated through hole through the multi-layered interconnect structure electrically connected to at least one member of said first plurality of electrically conductive members, to at least one of said first plurality of shielded signal conductors, and to at least one member of said 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 first high density interconnect layer for providing an electrical path from a first electronic device to the first plurality of shielded signal conductors.
