An improved procedure for fabricating step-edge Josephson junctions by YBCO on NdGaO3 substrates is described. It is based on a reactive patterning of the superconducting film geometry by using a SiOx inhibit process. SQUID's have been fabricated following this technique. Preliminary measurements on

High-T= step-edge junctions have successfully been fabricated on chemically etched MgO substrate steps. Epitaxial thin films of YBa2Cu,0,\_6 have been prepared utilizing an off-axis RF magnetron sputtering method. AFM observations were made to investigate surface morphology of the etched substrate a
