摘　　要：Josephson junction array chips for microvolt applications have been designed and fabricated. A voltage step as small as 1 μV has been observed for a single junction in the array when it is driven by 483.59 MHz microwave. By selecting different parts of the array, it can output a voltage from 1 μV to 256 μV. The flat region of the voltage steps is over 200 μA.This kind of array is useful for potential microvolt applications.Josephson junction array chips for microvolt applications have been designed and fabricated.
