A semiconductor package includes a support substrate having connection wirings disposed therein. At least one capacitor is disposed on the support substrate. The capacitor has first and second electrodes that are exposed from an upper surface of the support substrate. A redistribution wiring layer covers the upper surface of the support substrate. The redistribution wiring layer has redistribution wirings electrically connected to the connection wirings and the first and second electrodes respectively. A semiconductor chip is disposed on the redistribution wiring layer. The semiconductor chip has chip pads that are electrically connected to the redistribution wirings and outer connectors disposed on a lower surface of the support substrate and electrically connected to the connection wirings.
