In the absence of useful Josephson tunnel junctions made from cuprate superconductors, microbridges of various types are the only useful active devices for HTS electronics applications. A variety of techniques now exist to reproducibly engineer microbridges in high-quality epitaxial YBCO films. This paper reports on two such techniques from our own group that has resulted in high-yield processes for fabricating both dc and rf SQUIDs operating at temperatures as high as 82 K. The authors compare the results on these devices--step-edge microbridges and focused-ion beam microbridges--- with those on several other structures under investigation by other researchers.
