Patent ID: 7999359

Claim:
A semiconductor package, comprising: an electromagnetic shield defining a first inwardly recessed cavity; a first substrate having a first upper surface and a first lower surface, the first upper surface having a first die provided thereon, the first lower surface defining a second cavity partially accommodating the electromagnetic shield; a second substrate having a second upper surface and a second lower surface and defining at lease one via therethrough, the second upper surface having a second die provided thereon, wherein the electromagnetic shield is grounded through the at least one via; and a plurality of conductive metal elements provided on the first lower surface of the first substrate and the second lower surface of the second substrate, the conductive metal elements on the first lower surface of the first substrate electrically interconnecting the first substrate with the second substrate, the conductive metal elements on the second lower surface of the second substrate constituting an electrical input/output interface for the second substrate; wherein the first substrate is stacked over the second substrate, the electromagnetic shield is disposed above the second die to separate the second die from the first die, and the second die is received in the first cavity of the electromagnetic shield.
