An integrated circuit (IC) package includes an IC chip and a package carrier. The IC chip includes a substrate and an IC layered structure configured on an active surface of the substrate. The IC layered structure includes a first physical layer interface and a second physical layer interface. The first physical layer interface includes a plurality of first bump pads and a plurality of first inner pads electrically connected to the first bump pads, respectively. The second physical layer interface includes a plurality of second bump pads and a plurality of second inner pads electrically connected to the second bump pads, respectively. The second bump pads are mirror images of the first bump pads with respect to a first geometric plane perpendicular to the active surface. The second inner pads are mirror images of the first inner pads with respect to the first geometric plane.

Integrated circuit package and physical layer interface arrangement

An arrangement of non-signal through vias suitable for a wiring board is provided. The wiring board has a contact surface, a core layer and pads. The contact pads are disposed on the contact surface, while the arrangement of non-signal through vias includes first non-signal through vias and a second non-signal through via. The first non-signal through vias pass through the core layer and are electrically connected to some of the contact pads. The second non-signal through via which passes through the core layer is disposed between the first non-signal through vias and is not electrically connected to the contact pads. The interval between the second non-signal through via and anyone of the surrounding first non-signal through vias is smaller than or equal to 0.72 times of the minimum interval between any two of the contact pads electrically connected to the corresponding first non-signal through vias.
