    摘要: A conductive pattern structure includes a first insulating interlayer on a substrate, metal wiring on the first insulating interlayer, a second insulating interlayer on the metal wiring, and first and second metal contacts extending through the second insulating interlayer. The first metal contacts contact the metal wiring in a cell region and the second metal contact contacts the metal wiring in a peripheral region. A third insulating interlayer is disposed on the second insulating interlayer. Conductive segments extend through the third insulating interlayer in the cell region and contact the first metal contacts. Another conductive segment extends through the third insulating interlayer in the peripheral region and contacts the second metal contact. The structure facilitates the forming of uniformly thick wiring in the cell region using an electroplating process.

    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.
