Abstract
Microelectronic assemblies, related devices and methods, are disclosed herein. In some embodiments, a microelectronic assembly may include a first die in a first dielectric layer; a magnetic core inductor, having a first surface and an opposing second surface, in the first dielectric layer, including a first conductive pillar, having a first end at the first surface of the magnetic core inductor and an opposing second end at the second surface, at least partially surrounded by a magnetic material that extends at least partially along a thickness of the first conductive pillar from the second end and tapers towards the first end; and a second conductive pillar coupled to the first conductive pillar; and a second die in a second dielectric layer on the first dielectric layer coupled to the second surface of the magnetic core inductor.
