Abstract
An improved procedure for fabricating step-edge Josephson junctions by YBCO on NdGaO3 substrates is described. It is based on a reactive pat terning of the superconducting film geometry by using a SiO(x) inhibit process. SQUID's have been fabricated following this technique. Preli minary measurements on the transport properties in single junctions an d on the magnetic response in DC SQUID's are reported. Promising resul ts have been obtained at T = 4.2 K.
