Abstract:
The present disclosure is directed to systems and methods for improving the impedance matching of semiconductor package substrates by incorporating one or more magnetic build-up layers proximate relatively large diameter, relatively high capacitance, conductive pads formed on the lower surface of the semiconductor package substrate. The one or more magnetic layers may be formed using a magnetic build-up material deposited on the lower surface of the semiconductor package substrate. Vias conductively coupling the conductive pads to bump pads on the upper surface of the semiconductor package substrate pass through and are at least partially surrounded by the magnetic build-up material.

Claim (Index 9):
A semiconductor interconnect fabrication method, comprising:\n disposing at least one magnetic build-up layer proximate at least a portion of a first surface of a substrate; forming a plurality of vias in the substrate, each of at least some of the plurality of vias passing through the at least one magnetic build-up layer such that the at least one magnetic build-up layer is disposed about at least a portion of an external perimeter of the respective via; forming a plurality of bump pads across at least a portion of a second surface of the substrate, the second surface transversely opposed across a thickness of the substrate to the first surface, conductively coupling each of at least a portion of the plurality of bump pads to a respective one of the plurality of vias; and forming a plurality of conductive ball pads across at least a portion of the first surface of the substrate, each of at least a portion of the plurality of conductive ball pads disposed proximate the at least one magnetic build-up layer, each of the conductive ball pads having a first capacitance at a first frequency; and conductively coupling each of at least a portion of the plurality of conductive ball pads to a respective one of the plurality of vias.
