Abstract:
A process for forming a multilayer ceramic substrate, the process comprising:forming a universal monolith comprised of a plurality of self-supporting universal ceramic layers, wherein the universal monolith includes at least one conductive pathway extending therethrough and wherein a lowermost surface is adapted to electrically communicate with a first electrical component; forming a custom monolith comprised of a plurality of self-supporting custom ceramic layers, wherein the custom monolith includes a conductive pathway extending therethrough and wherein an uppermost surface is adapted to electrically communicate with a second electrical component; placing the custom monolith onto the universal monolith and aligning each one of the conductive pathways in the custom monolith with a corresponding conductive pathway in the universal monolith; and bonding the custom monolith to the universal monolith to form a multilayer ceramic substrate, wherein a continuous conductive pathway extends therethrough.
