Patent ID: 8872319

Claim:
A stacked package structure comprising: a stacked package including a lower semiconductor package, an upper semiconductor package disposed on the lower semiconductor package and spaced a predetermined distance apart from the lower semiconductor package, an inter-package connecting portion electrically connecting the lower semiconductor package and the upper semiconductor package while supporting a space therebetween, and an insulation layer disposed at least outside the inter-package connecting portion and filling the space between the lower semiconductor package and the upper semiconductor package; and an electromagnetic shielding layer surrounding lateral and top surfaces of the stacked package, wherein the inter-package connecting portion includes a plurality of inter-package connecting conductors disposed at least between the lower semiconductor package and the upper semiconductor package, including a set of outer-most inter-package connecting conductors and a set of inner inter-package connecting conductors, the two sets comprising all of the inter-package connecting conductors between the lower semiconductor package and the upper semiconductor package, and wherein the insulation layer contacts at least some of the outer-most inter-package connecting conductors and the electromagnetic shielding layer and does not contact any of the inner inter-package connecting conductors.
