    Abstract: Semiconductor devices may include a substrate, an active region that is on the substrate and extends in a first direction, a gate structure that traverses the active region and extends in a second direction that may be different from the first direction, a source/drain region on the active region adjacent a side of the gate structure, an insulating layer on the substrate, the gate structure and the source/drain region, and a contact structure that is in the insulating layer and is connected to the source/drain region. In the source/drain region, a contact region that is in contact with the contact structure includes first and second side regions spaced apart from each other in the second direction and a central region between the first and second side regions, and at least one of the first and second side regions may include a recess.

    Abstract: A semiconductor device including a metal pattern on a semiconductor substrate; an etch stop layer covering the metal pattern, the etch stop layer including a sequentially stacked first insulation layer, second insulation layer, and third insulation layer; an interlayer dielectric layer on the etch stop layer; and a contact plug penetrating the interlayer dielectric layer and the etch stop layer, the contact plug being connected to the metal pattern, wherein the first insulation layer includes a first insulating material that contains a metallic element and nitrogen, wherein the second insulation layer includes a second insulating material that contains carbon, and wherein the third insulation layer includes a third insulating material that does not contain a metallic element and carbon.
