Abstract: The embodiment of the invention is about a novel interconnection structure which can be incorporated into a variety of connectors, as well as other types of interconnections in order to reduce crosstalk, to improve signal integrity and to achieve EM emission compliance. A 4-via (2 signal vias, 1 power via, and 1 ground via) interconnection structure was used for demonstrating the effect of the novel interconnection structure. The same concept can be applied to any multi-via and multi-layer interconnection structure such as PCB, IC packaging circuit, or die circuit. Vias that have an electrical property can be added adjacent to the basic 4-via interconnection structure to achieve a multi-via interconnection structure. For 1-via (1 signal via or 1 power via), 2-via (1 signal via and 1 ground via or 1 signal via and 1 power via) and 3-via (1 signal via, 1 ground via, and 1 power via) interconnection structure, the proposed interconnection structure based upon the same concept can be applied as well.

Abstract: The embodiment of the invention is about a novel via structure which can be incorporated into printed circuit boards, integrated circuit packages, and integrated circuits in order to reduce crosstalk, to improve signal integrity and to achieve EM emission compliance. A 4-layer (2 signal layers and 2 power layers or 2 signal layers and 2 ground layers) circuit board assembly was used for demonstrating the effect of the novel via structure. The same concept can be applied to any multi-layer circuit board. Layers that have an electrical property can be added above, under, or within the basic 4-layer circuit board to achieve a multi-layer circuit board. For 2-layer and 3-layer circuit boards, a deformed version of the proposed via structure based upon the same concept will be needed for a coplanar waveguide configuration.
