Exemplary embodiments of the present invention provides a three dimensional integrated circuit and a method for repairing the three dimensional integrated circuit which dispose a signal through silicon via (STSV) or a redundant through silicon via (RTSV) for each basic unit in which a through silicon via (TSV) and a switch are combined and connect repair paths among the basic units to efficiently repair a defective through silicon via which exists in a dense area by using a small number of redundant resources.
