Crosstalk reduction between signal layers in a multilayered package by variable-width mesh plane structures

A method of fabricating a multilayered ceramic package, comprising:

• receiving, by at least one computer system, an initial multilayered ceramic package design, wherein the initial multilayered ceramic package design comprises a plurality of signal layers, each signal layer having one or more signal lines, at least one mesh layer adjacent at least one signal layer of the plurality of signal layers, wherein the at least one mesh layer comprises a mesh of a plurality of interconnected mesh line segments referenced by connection to either voltage or ground, wherein each of the plurality of mesh line segments are set to a same width, and at least one via running through the at least one signal layer and the at least one reference mesh layer, wherein each of the plurality of mesh line segments is positioned at least a via clearance minimum distance from the at least one via;
• maintaining, by the at least one computer system, a first selection of mesh line segments of the plurality of mesh line segments at a first width and adjusting a second selection of mesh line segments of the plurality of mesh line segments to a second width, wherein the second width is greater than the first width, wherein the second selection of mesh line segments of the second width are positioned to contain crosstalk introduced by a selection of signal lines in at least one of the plurality of signal layers, wherein each of the plurality of mesh line segments is positioned at least the via clearance minimum distance for the at least one via, to generate a modified multilayered ceramic package design with mesh wiring of varying widths;
• removing, by the at least one computer system, at least one mesh line segment from among the first selection of mesh line segments in the initial multilayered ceramic package design, to generate the modified multilayered ceramic package design with mesh wiring of varying widths and at least one less mesh line segment than specified in the initial multilayered ceramic package design, to reduce the total metal fill for the plurality of mesh line segments to meet metal loading requirements for fabricating the at least one mesh layer;
• and
• controlling fabrication, by the at least one computer system, of the multilayered ceramic package based on the modified multilayered ceramic package design.
