    Abstract: An integrated circuit device includes a gate stack structure on a base layer, the gate stack structure having a gate insulating layer with a first dielectric layer on the base layer and having first relative permittivity, and a gate structure on the gate insulating layer, and a gate spacer structure on opposite side walls of the gate stack structure and on the base layer, the gate spacer structure including a buried dielectric layer buried in a recess hole of the gate insulating layer at a lower portion of the gate spacer structure on the base layer, and the buried dielectric layer including a same material as the first dielectric layer.

    Abstract: A semiconductor device includes first wiring line patterns on a support layer, second wiring line patterns on the first wiring line patterns, and a multiple insulation pattern. The first wiring line patterns extend in a first direction and are spaced apart from each other in a second direction. The support layer includes first contact hole patterns between the first wiring line patterns that are spaced apart from each other in the first and second directions. The second wiring line patterns extend in the second direction perpendicular and are spaced apart from each other in the first direction. The multiple insulation pattern is on an upper surface of the support layer where the first contact hole patterns are not formed, arranged in a third direction perpendicular to the first direction and the second direction, and between the first wiring line patterns and the second wiring line patterns.
