Patent ID: 7989895

Claim:
A stacked package device, comprising: a first package having a plurality of first organic dielectric layers, the first package comprising at least one first conductive layer positioned between two of the plurality of first organic dielectric layers, the at least one first conductive layer patterned to form at least one first passive device; a second package having a plurality of second organic dielectric layers, the second package comprising at least one second conductive layer positioned between two of the plurality of second organic dielectric layers, the at least one second conductive patterned to form at least one second passive device; and an electrical connector positioned between a bottom surface of the first package and a top surface of the second package; wherein the first package is electrically connected to the second package via the electrical connector; the plurality of first organic dielectric layers comprises at least one large loss tangent organic layer; the plurality of second organic dielectric layers comprises at least one low loss tangent organic layer; and the large loss tangent organic layer has a loss tangent greater than the low loss tangent organic layer.
