Microelectronic assemblies, related devices and methods, are disclosed herein. In some embodiments, a microelectronic
assembly may include a die surrounded by an insulating material, the die having a first conductive contact at a first surface and a second conductive contact at a second surface opposite the first surface, a first
redistribution layer (RDL), on the first surface of the die, including a first conductive pathway through a first
dielectric material electrically coupled to the first conductive contact of the die by a first solderless
metal-
metal interconnect; and a second RDL, on second surface of the die, including a second conductive pathway through a second
dielectric material electrically coupled to the second conductive contact of the die by a second solderless
metal-
metal interconnect, wherein a thickness of the die is between 20 microns and 45 microns. In some embodiments, a thickness of the die is between 60 microns and 75 microns.
