Patent ID: 7838776

Claim:
A circuitized substrate comprising: at least one dielectric layer having first and second opposite sides; first and second electrically conductive layers, each of said first and second electrically conductive layers having a first smooth side having an RMS surface roughness within the range of from about 0.1 to about 0.6 microns and further including a thin organic layer thereon and bonded to said first and second opposite sides of said at least one dielectric layer, respectively, and a second etched smooth side opposite said first smooth side and not including an organic layer thereon, said second etched smooth side for being bonded directly to a dielectric layer other than said at least one dielectric layer, both said first and second smooth sides of said first and second electrically conductive layers each having a surface roughness that substantially prevents electrical signal attenuation when electrical signals pass near the surfaces of said sides; and a circuit pattern formed within at least one of said electrically conductive layers having said first smooth side and said second etched smooth side.
