Multi-surface edge pads for vertical mount packages and methods of making package stacks are provided. Example substrates for vertical surface mount to a motherboard have multi-surface edge pads. The vertical mount substrates may be those of a laminate-based FlipNAND. The multi-surface edge pads have cutouts or recesses that expose more surfaces and more surface area of the substrate for bonding with the motherboard. The cutouts in the edge pads allow more solder to be used between the attachment surface of the substrate and the motherboard. The placement and geometry of the resulting solder joint is stronger and has less internal stress than conventional solder joints for vertical mounting. In an example process, blind holes can be drilled into a thickness of a substrate, and the blind holes plated with metal. The substrate can be cut in half though the plated holes to provide two substrates with plated multi-surface edge pads including the cutouts for mounting to the motherboard.

An electronic device may include a semiconductor die. The electronic device may include a first routing layer. The first routing layer may be coupled to the semiconductor die.

The first routing footprint may have a width greater than a width of the semiconductor die.

A second routing layer may be coupled to the first routing layer. A second plurality of routing traces may be in electrical communication with the first plurality of routing traces. The second plurality of routing traces may be positioned within a second routing footprint. The second routing footprint may have a width greater than the width of the first routing footprint.

A wafer level fan out semiconductor device and a manufacturing method thereof are provided. A first sealing part is formed on lateral surfaces of a semiconductor die.

The solder balls are exposed to the outside through the second sealing part. Since the first sealing part and the second sealing part are formed of materials having thermal expansion coefficients which are the same as or similar to each other, warpage occurring to the wafer level fan out semiconductor device can be suppressed.

Embodiments of the present disclosure describe integrated circuit (IC) package assemblies and methods of fabricating IC package assemblies. These embodiments include dies embedded in embedding substrates to provide larger pitch interconnects to facilitate coupling to substrates or circuit boards through flip chip techniques. The embedding substrates may contain conductive pathways for coupling die contacts to larger pitch contacts located on the embedding substrate. By embedding the dies in the embedding substrates, dies having smaller pitch contacts can be used in package assemblies with larger pitch components without the need for silicon interposers and without having to utilize more stringent pick and place operations. Other embodiments may be described and/or claimed.
