Abstract: Embodiments disclosed include a multilayer substrate for semiconductor packaging. The substrate may include a first layer with a first side with an xy-plane and individual locations on the first side have a first side distance below the first side xy-plane, and a second side with a second side xy-plane and individual locations on the second side may have a second side distance below the second side xy-plane; and a second layer with a first side coupled to the second side of the first layer and a second side opposite the first side of the second layer, wherein a thickness of the second layer at the individual locations on the second layer may be comprised of the first side distance plus the second side distance. Other embodiments may be described and/or claimed.

Abstract: Embodiments that allow multi-chip interconnect using organic bridges are described. In some embodiments an organic package substrate has an embedded organic bridge. The organic bridge can have interconnect structures that allow attachment of die to be interconnected by the organic bridge. In some embodiments, the organic bridge comprises a metal routing layer, a metal pad layer and interleaved organic polymer dielectric layers but without a substrate layer. Embodiments having only a few layers may be embedded into the top layer or top few layers of the organic package substrate. Methods of manufacture are also described.

Abstract: This disclosure relates generally to an electronic package and methods that include an electrically conductive pad, a package insulator layer including a substantially non-conductive material, the package insulator layer being substantially planar, and a via. The via may be formed within the package insulator layer and electrically coupled to the electrically conductive pad. The via may include a conductor extending vertically through at least part of the package insulator layer and having a first end proximate the electrically conductive pad and a second end opposite the first end and a finish layer secured to the second end of the conductor, the finish layer including a gold compound.
