    摘要: Certain embodiments relate to routing structures and their formation. In one embodiment a routing structure includes a first region including a first layer comprising alternating signal traces and ground traces separated by a dielectric. The first region also includes a second layer including alternating signal traces and ground traces separated by a dielectric, wherein the second layer signal positioned over the first layer ground traces, and the second layer ground traces positioned over the first layer signal traces. The first region may also include additional layers of alternating signal and ground traces. The first region may also be formed with the ground traces having a width that is larger than that of the signal traces. The routing structure may also include a second region including pads to which the traces are coupled. Other embodiments are described and claimed.

    摘要: X-line routing arrangements for dense multi-chip-package interconnects are described. In an example, an electronic signal routing structure includes a substrate. A plurality of layers of conductive traces is disposed above the substrate. A first pair of ground traces is disposed in a first of the plurality of layers of conductive traces. A signal trace is disposed in a second of the plurality of layers of conductive traces, below the first layer. A second pair of ground traces is disposed in a third of the plurality of layers of conductive traces, below the first layer. The first and second pairs of ground traces and the signal trace provide an X-pattern routing from a cross-sectional perspective.

    摘要: Capacitively coupled vertical transitions may be configured with a desired amount of mutual capacitance to at least partially cancel crosstalk for an overall channel crosstalk (e.g., FEXT) reduction. In embodiments, capacitive coupling of adjacent vertical transitions is achieved with overlapping metal surfaces within the vertical transitions. In embodiments, one or more of the overlapping metal surfaces are vias, via pads, or metal stub features extending off a vertical transition. In embodiments, signal paths with overlapped vertical transitions are utilized to achieve crosstalk reduction of more than one victim-aggressor pair and/or to achieve crosstalk reduction of more than two aggressors. In embodiments, capacitively coupled vertical transitions are implemented in a package substrate, an interposer, or a printed circuit board.
