Abstract: The present invention relates to a through silicon via (TSV). The TSV is disposed in a substrate including a via opening penetrating through a first surface and a second surface of the substrate. The TSV includes an insulation layer, a barrier layer, a buffer layer and a conductive electrode. The insulation layer is disposed on a surface of the via opening. The barrier layer is disposed on a surface of the insulation layer. The buffer layer is disposed on a surface of the barrier layer. The conductive electrode is disposed on a surface of the buffer layer and a remainder of the via opening is completely filled with the conductive electrode. A portion of the buffer layer further covers a surface of the conductive electrode at a side of the second surface and said portion is level with the second surface.

Abstract: A method of forming a semiconductor device is disclosed. Provided is a substrate having at least one MOS device, at least one metal interconnection and at least one MOS device formed on a first surface thereof. A first anisotropic etching process is performed to remove a portion of the substrate from a second surface of the substrate and thereby form a plurality of vias in the substrate, wherein the second surface is opposite to the first surface. A second anisotropic etching process is performed to remove another portion of the substrate from the second surface of the substrate and thereby form a cavity in the substrate, wherein the remaining vias are located below the cavity. An isotropic etching process is performed to the cavity and the remaining vias.
