Patent ID: 7648858

Claim:
A method of manufacturing a multi-layer package structure, comprising: providing a substrate having an adhesive layer thereon; attaching first surfaces of a plurality of electronic components to the adhesive layer, wherein the plurality of electronic components have the first surfaces and second surfaces that are opposite the first surfaces; forming an insulating layer with first portions disposed in contact with the second surfaces of the plurality of electronic components and with second portions disposed in contact with the adhesive layer; forming an electrically conductive encapsulant structure over the insulating layer, resulting in a structure in which the first portions of the insulating layer are positioned between the conductive encapsulant structure and the second surfaces of the plurality of electronic components, and in which the second portions of the insulating layer are positioned between the adhesive layer and the conductive encapsulant structure; detaching the adhesive layer from the first surfaces of the plurality of electronic components and the second portions of the insulating layer; forming multi-layer circuitry over, and in electrical communication with, the first surfaces of the plurality of electronic components; and forming a shielding via through the multilayer circuitry and the second portions of the insulating layer such that the shielding via directly contacts the conductive encapsulant structure.
