发明名称 Method and apparatus for die stacking
摘要 An integrated circuit package is constructed by attaching lower dies to a substrate that has bond fingers deposited on its surface. One lower die and its associated bond fingers are located offset from the center of the substrate. The lower dies are electrically coupled to the substrate's bond fingers with lower bond wires. An upper die is stacked on at least one of the lower dies. The upper die is electrically coupled, with bond wires, to the lower die upon which it is mechanically coupled. Each of the lower dies may be coupled to the other lower die with bond wire bridges that span the lower bond wires. The upper die may be electrically coupled, with bond wire bridges, to any or all of the lower dies.
