                      Josephson tunnel junctions based on Nb/Al2O3/NiCu/Nb stacks
                      with a thickness step in the metallic NiCu interlayer were
                      fabricated. The step height of a few 0.1 nm was defined by
                      optical lithography and controlled etching of both Nb and
                      NiCu layers. Experimentally determined junction parameters
                      by current-voltage characteristics and Fraunhofer pattern
                      indicate a uniform NiCu thickness and similar interface
                      transparencies for etched and non-etched parts. The critical
                      current diffraction pattern was calculated and measured for
                      stepped junctions having the same ground phase difference
                      but different critical current densities in both halves. The
                      measured data show a good agreement with simulations.},
