The disclosure relates to a shielded electronic module which includes a module shielding structure and an electronic module with an interposer, a shielded electronic submodule over the interposer, and a module mold compound over the interposer and encapsulating sides of the shielded electronic submodule. Herein, the shielded electronic submodule includes an electronic submodule and a submodule side shielding structure, which covers sides of the electronic submodule to provide the sides of the shielded electronic submodule. A top surface of the electronic module is a combination of a top surface of the module mold compound and a top surface of the shielded electronic submodule, which is not covered by the module mold compound. The module shielding structure directly and continuously covers the top surface and sides of the electronic module, such that the submodule side shielding structure is electrically connected to the module shielding structure to individually shield the electronic submodule.

Compartmentalized shielding of a module utilizing self-shielded sub-modules

The disclosure is directed to an electronic device with a solder interconnect and multiple material encapsulant. The electronic device includes a die last assembly with the die assembled to an electronic packaging substrate by a solder interconnect. At least a portion of a first dielectric material and the die are milled or ground, with a second dielectric material applied over an exposed portion of the die. A shield is then positioned over and electrically insulated from the die. Accordingly, such a configuration reduces a thickness or height of an electronic device with shielding and a die last assembly.

Electronic device with solder interconnect and multiple material encapsulant

The present disclosure relates to a packaging process using a low pressure encapsulant. According to an exemplary process, an assembly including a substrate, a surface mounted device (SMD) mounted on the substrate, and a space between the SMD and the substrate is provided. The SMD has a sealed cavity biased towards the substrate. A sheet mold compound is laid over the SMD and the assembly is heated such that the sheet mold compound transitions to a liquid phase to form a molten mold compound. Next, the assembly is subjected to a vacuum that creates a negative atmosphere allowing the molten mold compound to flow towards the top surface of the substrate and about the SMD. The molten mold compound is then pressed towards the substrate at a low pressure (&#x3c;=2 Mpa) such that the space between the SMD and the substrate is substantially filled and the SMD is substantially encapsulated.

Low pressure encapsulant for size-reduced semiconductor package

Embodiments include but are not limited to apparatuses and systems including microelectronic devices including a package substrate, a plurality of electronic components disposed on and electrically coupled with the package substrate at one or more sides of the package substrate, one or more hollow cavity sheet molds surrounding the plurality of electronic components and coupled with one or more sides of the package substrate, and a plurality of through-mold vias to couple the package substrate with an external surface of at least one of the one or more hollow cavity sheet molds. The microelectronic device may be a chip-scale package or module. Methods and systems for making the same also are described.
