Abstract

Disclosed embodiments include an embedded thin-film capacitor and a magnetic inductor that are assembled in two adjacent build-up layers of a semiconductor package substrate. The thin-film capacitor is seated on a surface of a first of the build-up layers and the magnetic inductor is partially disposed in a recess in the adjacent build up layer. The embedded thin-film capacitor and the integral magnetic inductor are configured within a die shadow that is on a die side of the semiconductor package substrate.
