Abstract
The specification describes interconnection layouts for chip-on-chip packages using solder bump interchip connections as vias between a single level metal interconnection pattern on the lower support IC chip and another single level interconnection pattern on the upper IC chip. This arrangement allows for the formation of air isolated crossovers of features on either chip.
