A method of forming an integrated circuit package may include forming a first layer of a package substrate and mounting an interposer structure on the first layer of a substrate. In some instances, adhesive is used to attach the interposer structure to the first layer of the substrate. After the interposer structure is mounted on the first layer of the substrate, at least one hole is formed through the interposer structure. The hole may be filled with a conductive material such as copper to form a through-hole via in the interposer structure. A second layer of the substrate may be formed over the interposer structure and the first layer of the substrate. Integrated circuit (IC) dies may be mounted on the substrate and signals may be routed between the IC dies via the interposer structure embedded in the substrate.
