Abstract

An apparatus and method enabling a reduction in a resistance of a conductive path electrically connecting an upper substrate and a lower substrate. The apparatus includes a first semiconductor layer with element formation regions disposed adjacent to one another via element isolation regions, each of the element formation regions having a first active element, contact regions on an element isolation region side of a front layer portion of the element formation regions, conductive pads connected to the contact regions and extending across the element isolation region, a first insulating layer, a second semiconductor layer on the first insulating layer and having a second active element, a second insulating layer covering the second semiconductor layer, and conductive plugs extending from the second insulating layer to the conductive pad, the conductive plugs including a material identical to a material of the conductive pad and formed integrally with the conductive pad.
