Trace/via hybrid structure multichip carrier
A method of forming an multi-chip carrier that includes providing a trace structure using an additive forming method. The method includes forming a metal layer on a trace structure to provide electrically conductive lines. A dielectric material may then be formed on the electrically conductive lines to encapsulate a majority of the electrically conductive lines. The ends of the electrically conductive lines that are exposed through the upper surface of the dielectric material provide a top processor mount location and the ends of the electrically conductive lines that are exposed through the sidewalls of the dielectric material provide a sidewall processor mount location.
