Abstract: A semiconductor package includes a semiconductor chip including an electrode pad formed on the top surface thereof, a passive device embedded in the semiconductor package, the passive device having no functional electrode on the top surface thereof, a cover layer covering the semiconductor chip and the passive device, and at least one electrode pattern formed on the cover layer to transmit electrical signals. The cover layer includes at least one first opening formed to expose a region in which the functional electrode is to be formed. The electrode pattern includes a functional electrode portion formed in a region in which the functional electrode of the passive device is to be formed through the first opening. In the process of forming the electrode pattern, a functional electrode of the passive device is formed together therewith, thereby eliminating a separate step of manufacturing a functional electrode and thus reducing manufacturing costs.

Abstract: An energy harvesting apparatus, system, and method are provided to perform energy harvesting and estimation of ambient energy intensity. The energy harvesting apparatus includes an energy converter, an energy storage, an output voltage/current detector, and a switch. The energy converter receives ambient energy, converts the ambient energy into DC power having a DC voltage and a DC current, and outputs the DC power. The energy storage receives and stores the DC power. The output voltage/current detector has a constant load value and detects at least one of the DC voltage and the DC current, outputted from the energy converter, to be used for estimating intensity of the ambient energy. The switch selectively connects the energy converter to the energy storage or the output voltage/current detector.
