Disclosed are any electronic system or module which includes embedded actives and discrete passives, and methods for use in fabricating packages containing embedded active devices and/or discrete passive devices. Exemplary apparatus comprises a plurality of build-up layers defining circuit interconnections and that comprise one or more thin film type of embedded passive devices, at least a cavity formed in the build-up layers, and at least an active device and/or at least a discrete passive device disposed in the cavity and electrically connected to the circuit interconnections of the build-up layers. A stiffener may be coupled to an exposed (back) surface of the active device and to an adjacent surface of the build-up layers. The build-up layers may be mounted to a core, and the core may be attached to a printed circuit board. Alternatively, a bottom surface of the build-up layers may be mounted to a printed circuit board without core. The packages have a chip reworkability, an easier thermal management, a very thin profile and enhanced electrical performance comparable to packages produced using chip-first or chip-middle approaches.
