Patent ID: 8120148

Claim:
A package structure with an embedded die, the package structure comprising: a core layer, having a first surface and a second surface opposite to each other, the core layer comprising: a first dielectric layer; a leadframe; a die, disposed on and electrically connected to the leadframe, wherein the die and the leadframe are embedded in the first dielectric layer; a first signal layer, disposed on an upper surface of the first dielectric layer and electrically connected to the leadframe; and a second signal layer, disposed on a bottom surface of the first dielectric layer and electrically connected to the leadframe; a first build-up wiring structure, disposed on the first surface, wherein the first build-up wiring structure has a second dielectric layer and a first surface circuit layer, and the first surface circuit layer is electrically connected to the first signal layer; and a second build-up wiring structure, disposed on the second surface, wherein the second build-up wiring structure has a third dielectric layer and a second surface circuit layer, and the second surface circuit layer is electrically connected to the second signal layer.
