METHOD FOR MAKING HIGH-SPEED CERAMIC MODULES WITH HYBRID REFERENCING SCHEME FOR IMPROVED PERFORMANCE AND REDUCED COST

摘要

A multi-layered ceramic package comprises: a signal layer with identified chip/device area(s) that require a supply of power; and a voltage power (Vdd) layer and a ground (Gnd) layer disposed on opposite sides directly above or below and adjacent to the signal layer and providing a first reference mesh plane and a second reference mesh plane configured utilizing a hybrid mesh scheme. The hybrid mesh scheme comprises: a full dense mesh in a first area directly above or below the identified chip/device area(s); a half dense mesh in a second area that is above or below the edge(s) of the chip/device area; and a wider mesh pitch in all other areas The Vdd traces are aligned to run parallel and adjacent to signal lines in those other areas. Wider traces are provided within the mesh areas that run parallel and adjacent to signal lines.
