Among various methods, devices, and apparatuses, a number of methods are provided for forming a gap between circuitry. One such method includes depositing a first oxide precursor material on at least two conductive lines having at least one gap between the at least two conductive lines, and forming a breadloaf configuration with the first oxide precursor material on a top of each of the at least two conductive lines that leaves a space between a closest approach of at least two adjacent breadloaf configurations. The method also includes depositing a second oxide precursor material over the first oxide precursor material, where depositing the second oxide precursor material results in closing the space between the closest approach of the at least two adjacent breadloaf configurations.

摘要:
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.

摘要:
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.
