A semiconductor device has a substrate, an insulating interlayer, an interconnect as one example of an electro-conductive pattern, a through-electrode, and a bump as one example of a connection terminal, wherein the insulating interlayer is positioned up above the surface of the substrate, the interconnect is positioned on the surface of the insulating interlayer, the through-electrode extends through the substrate and the insulating interlayer, from the back surface of the former to the surface of the latter, one end of which is connected to the interconnect, and the bump is provided on the back surface side of the substrate, and connected to the other end of the through-electrode.
