Claims

[Scope of utility model registration request]

A superconducting integrated circuit and a chip having a plurality of pads as terminals for taking out electrical signals from this circuit formed on the same main surface are mounted, the superconducting integrated circuit is cooled to a temperature at which it operates, and an electrical signal is applied to the chip. A measuring jig for a chip equipped with a superconducting integrated circuit that transmits and receives signals to determine the quality of the chip, has a concave portion whose bottom surface is approximately equal to the striped shape of the main surface of the chip, and which is slightly larger than the chip. Spring contacts are implanted in the bottom surface of the recess at intervals equal to the array spacing of the pads on the chip, and the chip to be measured is placed in the recess with the main surface having the pads facing the spring contacts. A pressurizing block, which is attached in the direction of contact and whose lower surface shape is approximately equal to the back surface shape of the chip to be measured and has a notch around the lower surface, is placed in the recess to bring the bat and the spring contact into close contact with each other. A measuring device for a chip equipped with a superconducting integrated circuit, characterized in that the chip and the pressure block are fixed by means of fixing means for the pressure block provided on the side surface of the recess when the chip and the pressure block are inserted so as to overlap with each other.
