ABSTRACT:
An integrated circuit device comprises a plurality of integrated circuit layers formed on a semiconductor substrate, a wiring layer having a ladder-like lattice and formed of a material exhibiting superconductivity in a longitudinal direction, the wiring layer connecting arbitrary integrated circuit layers of the plurality of integrated circuit layers, and an isolation layer having a ladder-like lattice and formed of the same material as the wiring layer such that a resistance in a widthwise direction is higher than that in a longitudinal direction, the isolation layer isolating an arbitrary integrated circuit layer of the plurality of integrated circuit layers.
