Abstract:
1. An interconnect structure, comprising: a substrate comprising a first layer, wherein the first layers has a first surface plane and a second surface plane; a pair of interconnect pads formed on the first surface plane of the first layer of the substrate; and a pair of differential signal transmission lines formed on the first surface plane of the first layer, the pair of differential signal transmission lines having a Y-type close trace portion for connection to the pair of interconnect pads and connected to the pair of interconnect pads at open ends of the Y-type close trace portion, wherein the first surface plane of the first layer is formed with a via hole which is formed within a groin region defined by the Y-type close trace portion and extends to the second surface plane of the first layer, the second surface plane being a power plane or a ground plane while the first surface plane being a non-ground plane.
