Abstract
A pair of superconducting electrodes are so formed as to interpose a smeiconductor therebetween, and a control electrode is formed on the seimiconductor through an insulator film so as to control the superconductive weak coupling state in the semiconductor between the superconducting electrodes. The distance between the superconducting electrodes is determined by the thickness of the superconductor interposed between the two electrodes, whereby the interelectrode distance is settled with a high precision to improve the uniformity of the device characteristic. And in an arrangement where two superconducting electrodes are formed on a semiconductor layer and the superconductive weak coupling state between such two electrodes is controlled by a third electrode, the gain is increadable by furnishing a varied impurity distribution in the semiconductor layer.
