Abstract
We discuss our multilayer YBCO process which uses step-edge junctions. Key issues are dielectric defect density, wiring layer critical curre nt over edges of underlying features and junction critical current uni formity. We have demonstrated an average defect density of about 450/c m(2) over many wafers. Wiring critical current exceeds 1 mA/mu m of li ne width. We have demonstrated SQUIDs at 77 K using this process.
