ABSTRACT:
An interposer is made of nested drawn copper shells with insulation between them. The shells are etched using methods of ordinary printed wiring fabrication, but being three dimensional, straight runs from the die to the motherboard can be made optimally short and wide without passing through any vias. Some shells can extend upward for top connections, and vias and crossing landlines can be used as required in the areas away from the die.
