Abstract:
1. A semiconductor device comprising: a semiconductor element substrate having first and second sets of contact electrodes; a passive semiconductor substrate mounted to oppose the semiconductor element substrate, the passive semiconductor substrate having opposing upper and lower surfaces, the lower surface of the passive semiconductor substrate facing the semiconductor element substrate; a passive element mounted on the lower surface of the passive semiconductor substrate, between the semiconductor element substrate and the passive semiconductor substrate; passive electrodes electrically connecting the passive element to the first set of contact electrodes of the semiconductor element substrate, the passive electrodes extending through the passive semiconductor substrate to be exposed on the upper surface of the passive semiconductor substrate; and through-electrodes electrically connected to the second set of contact electrodes of the semiconductor element substrate, the through-electrodes extending through the passive element without making electrical contact with the passive element, the through-electrodes extending through the passive semiconductor substrate to be exposed on the upper surface of the passive semiconductor substrate.
