摘要：

A new four-layer resist system was developed to fabricate small capacitance niobium tunnel junctions. Nb/AlO(x)/Al junctions were used to make a superconducting single electron transistor composed of two dc SQUIDs in series. The current-voltage characteristics were measured and two types of resonant tunneling of Cooper pairs were observed at different magnetic fields.
