US Patent 7648858 Methods and apparatus for EMI shielding in multi-chip modules

Methods and structures provide a shielded multi-layer package for use with multi-chip modules and the like. A substrate (102) (e.g., chip carrier) has an adhesive layer (104), where electronic components (106, 108) are attached. An insulating layer (110) is formed over the plurality of electronic components, and a conductive encapsulant structure (115) is formed over the insulating layer. The adhesive layer is detached from the electronic components, and multi-layer circuitry (140) is formed over, and in electrical communication with, the plurality of electronic components. A shielding via (150) is formed through the multilayer circuitry such that it contacts the conductive encapsulant.
