Claim 13:
14. A device comprising:
a package substrate having a die attach pad (DAP) and package pads;
a die disposed on the DAP, the die is electrically coupled to the package pads;
an encapsulation layer, the encapsulation layer covers the package substrate and the die, the encapsulation layer having a top encapsulation surface disposed above a top die surface;
a primary electromagnetic interference (EMI) shield structure, the primary EMI shield structure comprises a primary EMI planar member, the primary EMI planar member is disposed on the top encapsulation surface; and
a secondary EMI shield structure, the secondary EMI shield structure comprises
a secondary EMI planar member the secondary EMI planar member disposed on a top primary planar surface of the primary EMI planar member,
secondary EMI side members, the secondary EMI side members extend downwards from second planar member side surfaces of the secondary EMI planar member towards the package substrate,
the secondary EMI shield structure encases the primary EMI shield structure, the die and encapsulation layer, the secondary EMI shield structure serves as an external EMI shield structure of the device, and
wherein the secondary EMI shield structure is coupled to ground.
