Abstract: In an integrated circuit device and method of manufacturing the same, a conductive structure and a wiring structure are sequentially arranged on a substrate having a through hole. The conductive structure includes semiconductor chips and a contact structure. The wiring structure includes a metal line through which signals are transferred to the conductive structure. A penetration electrode is positioned in the through hole. The penetration electrode includes a conductive plug electrically connected to one of the conductive structure and the wiring structure, and a pair of a base layer and a gap interposed between the conductive plug and a sidewall of the through-hole, thereby enclosing the conductive plug. The base layer also includes a product of a solid reaction of reactants of which diffusion speeds are different. Accordingly, the dielectric characteristics of the penetration electrode are improved by using the gap as a dielectric gap.

Abstract: A memory device may include a cathode, an anode, a link connected to the anode, and a first connection element that connects the link to the cathode. The link and the anode may be located in a position lower than that of the cathode or the link and the anode may be located in a position higher than that of the cathode. Also, the cathode, the anode, the link, and the first connection element may be formed on the same plane.

Abstract: Provided are an electrical fuse device and a method of operating the same. The electrical fuse device may include a fuse link having a multi layer structure with at least two metal layers. The number of metal layers that are blown, from among the at least two metal layers, may vary according to either the duration of application of voltage or the strength of voltage applied.
