ABSTRACT A semiconductor device in which at least a part of each of the current flow paths extending from the electrode pads of the semiconductor chip to the outer terminals of the semiconductor package is made of superconducting material. During operation, when an overcurrent applied to a lead pin exceeds the critical current of the superconducting material, the resistance is increased from zero, and the semiconductor chip is thereby protected from damage. The superconducting material may also be configured between the outer terminals of the semiconductor package so that a potential difference can be measured. Also, a magnetic field may be applied to the superconducting material so that the critical current value can be set.
