Experimentally realizable 3D arrays of Josephson junctions have been a
goal of researchers since 2D Josephson junctions (JJ) arrays were fir
st introduced. In the past, it has proven to be technically impossible
to manufacture 3D proximity-coupled arrays. Recent advancements in et
ching technology have now made fabrication more feasible. Ln this pape
r, we present details of our fabrication process. (C) 1995 Academic Pr
