    摘要: Example embodiments herein relate to a method of fabricating a semiconductor device. The method may include forming a liner insulating layer on a surface of a gate pattern to have a first thickness. Subsequently, a gap fill layer may be formed on the liner insulating layer by flowable chemical vapor deposition (FCVD) or spin-on-glass (SOG). The liner insulating layer and the gap fill layer may be recessed such that the liner insulating layer has a second thickness, which is smaller than the first thickness, in the region in which a metal silicide will be formed. Metal silicide may be formed on the plurality of gate patterns to have a relatively uniform thickness using the difference in thickness of the liner insulating layer.

    摘要: A fuse base insulating region, for example, an insulating interlayer or a compensation region disposed in an insulating interlayer, is formed on a substrate. An etch stop layer is formed on the fuse base insulating region and forming an insulating interlayer having a lower dielectric constant than the first fuse base insulating region on the etch stop layer. A trench extending through the insulating interlayer and the etch stop layer and at least partially into the fuse base insulating region is formed. A fuse is formed in the trench. The fuse base insulating region may have a greater mechanical strength and/or density than the second insulating interlayer.

    摘要: In a method of manufacturing a metal wiring structure, a first metal wiring and a first barrier layer are formed on a substrate, and the first barrier layer is nitridated. An insulating interlayer is formed on the substrate so as to extend over the first metal wiring and the first barrier layer. Part of the insulating interlayer is removed to form a hole exposing at least part of the first metal wiring and part of the first barrier layer. A nitridation plasma treatment is performed on the exposed portion of the first barrier layer. A second barrier layer is formed along the bottom and sides of the hole. A plug is formed on the second barrier layer to fill the hole.
