Patent ID: 8502082

Claim:
A circuitized substrate comprising: a first electrically conductive layer with first and second opposing major surfaces, both of said surfaces having an RMS roughness value less than approximately 0.6 micron; a thin organic layer disposed on said first and second opposing major surfaces; first and second dielectric layers directly bonded to said first and second opposing major surfaces, respectively; second and third electrically conductive layers each having a first smooth side directly bonded to said first and second dielectric layers, respectively, said second and third electrically conductive layers each further including a second opposing side, all of said second and third layer first and second sides having an RMS roughness value less than approximately 0.6 micron; and a circuit pattern formed within at least one of said second and third electrically conductive layers having said first smooth surface and said second surface, whereby said substrate is formed with a polymer alternative.
