Abstract: 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.

Abstract: Embodiments of the present disclosure flip-chip packaging techniques and configurations. An apparatus may include a package substrate having a plurality of pads formed on the package substrate, the plurality of pads being configured to receive a corresponding plurality of interconnect structures formed on a die and a fluxing underfill material disposed on the package substrate, the fluxing underfill material comprising a fluxing agent configured to facilitate formation of solder bonds between individual interconnect structures of the plurality of interconnect structures and individual pads of the plurality of pads and an epoxy material configured to harden during formation of the solder bonds to mechanically strengthen the solder bonds. Other embodiments may also be described and/or claimed.

Abstract: A wafer level package includes an epoxy layer formed on an adhesive covered substrate during manufacturing for securing electrical components in place prior to being embedded in a molded material. An electrically conductive block is fixed in the epoxy layer. Vias are formed for accessing face up component contacts using a metalized layer on the surface of the molded material. After stripping the adhesive and substrate, the epoxy layer is penetrated to expose electrical contacts for face down components. An electrical connection is made between the face up and face down components using the block. Optionally, a dielectric layer covers the molded material and a second metalized layer placed on the dielectric layer to carry another electrical component embedded in a second dielectric layer covering the first dielectric layer. Thus a stacked component arrangement including multiple die and passive components is effectively fabricated into the wafer level package.
