Patent ID: 7981730

Claim:
A method for making a package assembly with integrated conformal EMI shielding, comprising: attaching a plurality of microelectronic devices to a releasable attachment device; forming an insulating layer over the a plurality of microelectronic devices; applying an embedded grounding frame on the insulating layer comprising one or more grounding elements that are positioned to surround each of the plurality of microelectronic devices; forming a conductive layer over the insulating layer, thereby forming a shielding structure over each of the plurality of microelectronic devices that is insulated from the plurality of microelectronic devices by the insulating layer and that is electrically connected to the embedded grounding frame; forming an encapsulation package over the conductive layer to encapsulate the plurality of microelectronic devices, the encapsulation package comprising a first surface that contacts the releasable attachment device; removing the removable attachment device from the first surface of the encapsulation package to thereby expose the plurality of microelectronic devices at the first surface of the encapsulation package; and forming a multi-layer circuit substrate on the first surface of the encapsulation package comprising a plurality of circuit substrate shielding via structures, each of which is in electrical contact with the embedded grounding frame and a corresponding shielding structure over a microelectronic device.
