    摘要: A semiconductor device includes a substrate, a conductive pattern, a side spacer, and an air gap. The substrate includes an interlayer insulating layer and a trench penetrating the interlayer insulating layer. The conductive pattern is disposed within the trench of the substrate. The side spacer is disposed within the trench. The side spacer covers an upper side surface of the conductive pattern. The air gap is disposed within the trench. The air gap is bounded by a sidewall of the trench, the side spacer, and a lower side surface of the conductive pattern. A level of a bottom surface of the conductive pattern is lower than a level of bottom surfaces of the side spacer.

    摘要: A semiconductor may include a first inter metal dielectric (IMD) layer, a first blocking layer on the first IMD layer, a metal wiring and a second blocking layer. The first inter metal dielectric (IMD) layer may be formed on a substrate, the first IMD layer may include a low-k material having a dielectric constant lower than a dielectric constant of silicon oxide. The first blocking layer may be formed on the first IMD layer. The first blocking layer may include an oxide having a dielectric constant higher than the dielectric constant of the first IMD layer. The metal wiring may be through the first IMD layer and the first blocking layer. The second blocking layer may be formed on the metal wiring and the first blocking layer. The second blocking layer may include a nitride. The first and second blocking layers may reduce or prevent from the out gassing, so that a semiconductor device may have good characteristics.

    摘要: Semiconductor devices may include a diffusion prevention insulation pattern, a plurality of conductive patterns, a barrier layer, and an insulating interlayer. The diffusion prevention insulation pattern may be formed on a substrate, and may include a plurality of protrusions protruding upwardly therefrom. Each of the conductive patterns may be formed on each of the protrusions of the diffusion prevention insulation pattern, and may have a sidewall inclined by an angle in a range of about 80 degrees to about 135 degrees to a top surface of the substrate. The barrier layer may cover a top surface and the sidewall of each if the conductive patterns. The insulating interlayer may be formed on the diffusion prevention insulation pattern and the barrier layer, and may have an air gap between neighboring ones of the conductive patterns.

    摘要: Methods of forming a wiring structure are provided including forming an insulating interlayer on a substrate and forming a sacrificial layer on the insulating interlayer. The sacrificial layer is partially removed to define a plurality of openings. Wiring patterns are formed in the openings. The sacrificial layer is transformed into a modified sacrificial layer by a plasma treatment. The modified sacrificial layer is removed by a wet etching process. An insulation layer covering the wiring patterns is formed on the insulating interlayer. The insulation layer defines an air gap therein between neighboring wiring patterns.
