A semiconductor device includes a plurality of insulating layers laminated on a substrate to cover passive elements such as a capacitor, an inductor, and the like, and to fix an IC chip in a face up state in one of the insulating layers. The insulating layers have similar structures in each of which the passive element or the semiconductor chip is disposed in at the bottom, a plug is formed in the insulating layer to pass therethrough in the thickness direction for extending an electrode of one of these elements to the top surface, and a conductive layer is provided as wiring on the top surface of the insulating layer to be connected to the plugs for electrically connecting respective elements or rearranging the electrode position. Also, an insulating layer is provided on the top for protecting the semiconductor device and for providing an external connecting electrode.
