Zusammenfassung:A semiconductor device is provided with: a reference unit in which at least two circuit modules are stacked with circuit layers adjoining each other; an additional unit in which at least two other circuit modules are stacked with circuit layers adjoining each other, the additional unit being stacked on the reference unit; and a via disposed through the reference unit and the additional unit and extending in a stacking direction. The via includes a reference via disposed in the reference unit, and an additional via disposed in the additional unit. The additional via at the position of contact with the reference via has a diameter smaller than a diameter of the reference via.
