Claim Text:
1. A semiconductor structure including a through electrode, comprising: a lamination body including at least three layers, the layers including respective electrode parts that are aligned vertically, the electrode part of an uppermost layer of the lamination body being on the surface of the uppermost layer and including a first aperture, the electrode part of the intermediate layer having a second aperture that has a diameter that is smaller than a diameter of the first aperture of the uppermost layer; a through-hole extending from the first aperture of the electrode part on the uppermost layer to an upper surface of the electrode part on a lowermost layer of the lamination body, wherein the electrode part on a lowermost layer does not include an aperture, the through-hole having a depressed part on a side wall thereof at a part between the electrode parts therein; an insulating layer disposed on the entire side wall in the through-hole at a part other than on surfaces of the electrode parts; and a conductive material, with which the through-hole is filled from the upper surface of the electrode part on the lowermost layer to the surface of the electrode part on the uppermost layer.
