Abstract
A package substrate is disclosed. The package substrate includes a substrate core, a cavity below the substrate core that extends from a surface of a first resist layer to a bottom surface of the package substrate, and a first terminal and a second terminal in the first resist layer. The package substrate also includes one or more passive components that are coupled inside the cavity to the first terminal and the second terminal.
