In a method of manufacturing a semiconductor device, a front end of line (FEOL) process may be performed on a semiconductor substrate to form a semiconductor structure. A back end of line (BEOL) process may be performed on the semiconductor substrate to form a wiring structure electrically connected to the semiconductor structure, thereby formed a semiconductor chip. A hole may be formed through a part of the semiconductor chip. A preliminary plug may have a dimple in the hole. The preliminary plug may be expanded into the dimple by a thermal treatment process to form a plug. Thus, the plug may not have a protrusion protruding from the upper surface of the semiconductor chip, so that the plug may be formed by the single CMP process.

For forming a semiconductor device, a via structure is formed through at least one dielectric layer and at least a portion of a substrate. In addition, a protective buffer layer is formed onto the via structure. Furthermore, a conductive structure for an integrated circuit is formed over the substrate after forming the via structure and the protective buffer layer, with the conductive structure not being formed over the via structure. Thus, deterioration of the conductive and via structures is minimized.

A semiconductor device includes a via structure and a conductive structure. The via structure has a surface with a planar portion and a protrusion portion. The conductive structure is formed over at least part of the planar portion and not over at least part of the protrusion portion of the via structure. For example, the conductive structure is formed only onto the planar portion and not onto any of the protrusion portion for forming high quality connection between the conductive structure and the via structure.

In methods of manufacturing a semiconductor device, a substrate having a first surface and a second surface opposite to the first surface is prepared. A sacrificial layer pattern is formed in a region of the substrate that a through electrode will be formed. The sacrificial layer pattern extends from the first surface of the substrate in a thickness direction of the substrate. An upper wiring layer is formed on the first surface of the substrate. The upper wiring layer includes a wiring on the sacrificial layer pattern. The second surface of the substrate is partially removed to expose the sacrificial layer pattern. The sacrificial layer pattern is removed from the second surface of the substrate to form an opening that exposes the wiring. A through electrode is formed in the opening to be electrically connected to the wiring.

A via structure may include a first conductive pattern, a buffer pattern, and a second conductive pattern. The first conductive pattern may be on an inner wall of a first substrate and the inner wall may define a via hole passing at least partially through the first substrate. The buffer pattern may be on the first conductive pattern and the buffer pattern may partially fill the via hole. The second conductive pattern may be on a top surface of the buffer pattern in the via hole.

A semiconductor device can include an insulation layer on that is on a substrate on which a plurality of lower conductive structures are formed, where the insulation layer has an opening. A barrier layer is on a sidewall and a bottom of the opening of the insulation layer, where the barrier layer includes a first barrier layer in which a constituent of a first deoxidizing material is richer than a metal material in the first barrier layer and a second barrier layer in which a metal material in the second barrier layer is richer than a constituent of a second deoxidizing material.
