A capacitor dielectric can be between the storage node and the electrode layer. A supporting pattern can be connected to the storage node, where the supporting pattern can include at least one first pattern and at least one second pattern layered on one another, where the first pattern can include a material having an etch selectivity with respect to the second pattern.

A method of fabricating a semiconductor device includes providing a substrate including a first region and a second region, forming a first trench having a first width in the first region and a second trench having a second width in the second region, and the second width is greater than the first width. The method also includes forming a first insulation layer in the first and second trenches, removing the first insulation layer in the second trench to form a first insulation pattern that includes the first insulation layer remaining in the first trench, forming on the substrate a second insulation layer that fills the second trench, and the second insulation layer includes a different material from the first insulation layer.

摘要:
A tunnel insulating layer and a charge storage layer are sequentially stacked on a substrate. A recess region penetrates the charge storage layer, the tunnel insulating layer and a portion of the substrate. The recess region is defined by a bottom surface and a side surface extending from the bottom surface. A first dielectric pattern includes a bottom portion covering the bottom surface and inner walls extending from the bottom portion and covering a portion of the side surface of the recess region. A second dielectric pattern is in the recess region between the inner walls of the first dielectric pattern, and the second dielectric pattern enclosing an air gap. The air gap that is enclosed by the second dielectric pattern may extend through a major portion of the second dielectric pattern in a direction away from the bottom surface of the recess region.

An integrated circuit device includes a plurality of stacked circuit layers, at least one of the plurality of circuit layers including a composite interlayer insulation layer including laterally adjacent first and second insulating material regions having different mechanical strengths and dielectric properties and a plurality of circuit components disposed in the composite interlayer insulation layer. The first insulating material region may have a lower dielectric constant and a lower mechanical strength than the second insulating material region such that, for example, the first insulating material region may be positioned near signal lines or other circuit features to reduce capacitance while using the second insulating material region near a location that is susceptible to localized mechanical stress, such as a fuse location, an external connection bonding location or a scribe line location.

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.
