Patent ID: 8466567

Claim:
An integrated circuit packaging system comprising: base device pads having device pad surfaces coplanar to each other characteristic of being formed on a carrier top side of a connection carrier; base interconnected pads having interconnect pad surfaces coplanar to each other characteristic of being formed on the carrier top side; a base integrated circuit connected to the base device pads; base vertical interconnects directly on the base interconnect pads; a base package substrate attached to the base integrated circuit and directly on the base vertical interconnects; a base encapsulation on the base package substrate, the base device pads, and the base interconnect pads, the base encapsulation partially exposing the base device pads and the base interconnect pads opposite the base package substrate; and base external interconnects attached to a base substrate bottom side of the base package substrate, wherein the base encapsulation includes a step portion over the base integrated circuit, the base encapsulation partially exposing the base device pads at the step portion.
