摘要： Methods of forming conductive pattern structures form an insulating interlayer on a substrate that is partially etched to form a first trench extending to both end portions of a cell block. The insulating interlayer is also partially etched to form a second trench adjacent to the first trench, and a third trench extending to the both end portions of the cell block. The second trench has a disconnected shape at a middle portion of the cell block. A seed copper layer is formed on the insulating interlayer. Inner portions of the first, second and third trenches are electroplated with a copper layer. The copper layer is polished to expose the insulating interlayer to form first and second conductive patterns in the first and second trenches, respectively, and a first dummy conductive pattern in the third trench. Related conductive pattern structures are also described.

摘要： A method of fabricating a semiconductor device includes forming switching devices on a substrate. A lower structure is formed in the substrate having the switching devices. A lower conductive layer is formed on the lower structure. Sacrificial mask patterns are formed on the lower conductive layer. Lower conductive patterns are formed by etching the lower conductive layer using the sacrificial mask patterns as an etch mask. An interlayer insulating layer is formed on the substrate having the lower conductive patterns. Interlayer insulating patterns are formed by planarizing the interlayer insulating layer until the sacrificial mask patterns are exposed. Openings exposing the lower conductive patterns are formed by removing the exposed sacrificial mask patterns. Upper conductive patterns self-aligned with the lower conductive patterns are formed in the openings.

摘要： A structure and formation method for electrically connecting aluminum and copper interconnections stabilize a semiconductor metallization process using an inner shape electrically connecting the aluminum and copper interconnections. To this end, a copper interconnection is disposed on a semiconductor substrate. An interconnection induction layer and an interconnection insertion layer are sequentially formed on the copper interconnection to have a contact hole exposing the copper interconnection. An upper diameter of the contact hole may be formed to be larger than a lower diameter thereof. A barrier layer and an aluminum interconnection are filled in the contact hole. The aluminum interconnection is formed not to directly contact the copper interconnection through the contact hole.

摘要： A gate structure is formed on a substrate. An insulating interlayer is formed covering the gate structure. The substrate is heat treated while exposing a surface of the insulating interlayer to a hydrogen gas atmosphere. A silicon nitride layer is formed directly on the interlayer insulating layer after the heat treatment and a metal wiring is formed on the insulating interlayer. The metal wiring may include copper. Heat treating the substrate while exposing a surface of the interlayer insulating layer to a hydrogen gas atmosphere may be preceded by forming a plug through the first insulating interlayer that contacts the substrate, and the metal wiring may be electrically connected to the plug. The plug may include tungsten.
