Abstract
We have developed a unique substrate terracing process to achieve two- dimensional arrays of high-T-c step-edge superconductor-normal metal-s uperconductor Josephson junctions. This process has been used to reali ze 3x3 and 3x6 antenna coupled arrays for direct detection of emission . An enhancement to this process incorporating a YBa2Cu3O7-delta base layer and a Nb/PdAu ground plane is described. This modification enabl ed the fabrication of arrays capacitively coupled to detector junction s for detection of emission at frequencies beyond 300 GHz. This report details the motivation, design, fabrication process, and preliminary results of several array experiments.
