An integrated circuit structure and a method of manufacturing, wherein the
method comprises forming a first via in an interconnect layer of the
substrate, wherein the first via comprises a first size diameter; and
forming a second via in the interconnect layer, wherein the second via
comprises a second size diameter, the second size diameter being
dimensioned larger than the first size diameter, wherein the second via
comprises a non-uniform circumference, and wherein the substrate is
configured in an approximately 1:1 ratio (i.e., approximately equal
number) of the first and second vias. The first and second vias are laser
formed or are formed by any of mechanical punching and photolithography.
The second via is formed by sequentially forming multiple partially
overlapping vias dimensioned and configured with the first size diameter.
The first and second vias are arranged in a grid to allow for wiring of
electronic devices.
