; ;
In this paper, Josephson junctions with double layer base electrodes are proposed, and their thermal cycling stability is reported. The double layer base electrode has been made of a thick Nb lower film and a thin Pb-In-Au upper film prepared at 77K. The thermal cycling experiment has been carried out for 11780 junctions, and their excellent cycling stability has been observed.
