摘要：
A fabrication process where controlled anodization is used to reduce the area of Nb/Al-AlOx/Nb Josephson tunnel junctions is presented. This process could be used to fabricate reproducible high-quality submicrometer junctions using photoresist masking pads of several square micrometer. For junctions with an area of 10x10 mu m(2), an edge reduction between 0.5 mu m and 1.75 mu m has been obtained, with a fine dependence on the anodization parameters.
