Abstract
An integrated circuit device includes a middle insulating structure on a substrate, a first contact structure passing through the middle insulating structure and extending by a first vertical length from a top surface of the middle insulating structure toward the substrate, and a second contact structure passing through the middle insulating structure. The middle insulating structure may have a top surface extending in a lateral direction at a first vertical level. The second contact structure may extend by a second vertical length greater than the first vertical length from the top surface of the middle insulating structure toward the substrate. The first contact structure may have a first top surface extending planar along an extension line of the top surface of the middle insulating structure. The second contact structure may have a second top surface, which may be convex in a direction away from the substrate.
