Abstract
Microelectronic assemblies, and related devices and methods, are disclosed herein. For example, in some embodiments, a microelectronic assembly may include a package substrate having a first surface and an opposing second surface, and a die secured to the package substrate, wherein the die has a first surface and an opposing second surface, the die has first conductive contacts at the first surface and second conductive contacts at the second surface, and the first conductive contacts are coupled to conductive pathways in the package substrate by first non-solder interconnects.
